Best Power Supply for GTX 1080 – Avoid One Big Mistake!

The GTX series is the long-standing powerhouse of graphics cards and the envy of every gamer. Touted as the fastest, most reliable, and visually impressive cards on the market, you can expect great things from any card in the GTX line. But the fan favorite in 2019 is still the GTX 1080. With as much punch as the 1080 packs, you may expect a need for a beefy, expensive power supply to run it at maximum. But do you actually need to spend that much?

Below, I’ll answer that question as we explore the best of the best in power supplies for the GTX 1080. This will guide you, should you complete or upgrade your ultimate gaming rig. You might be surprised how much power you can get for a relatively small price tag.

 

Why the GTX 1080 Is Amazing

Before we dive into the specs on some killer power for the GTX 1080, you need to know why this card is still a favorite among serious gamers. The GTX line of graphics cards is the epitome of gaming prowess, and it has been for many years. You can find it distributed through many different brands, but they’re all basically the same.

Powered by the Nvidia Pascal architecture, there isn’t a single game that can slow the 1080 down. Crank your games up to high and ultra-high graphics settings and hold onto your pants. They boast three times the performance of any previous generation of graphics cards. They can even handle the toughest and most graphics-intense VR games.

With so much happening inside these sleek and sexy cards, heat should be a real concern. But not for the GTX 1080. Innovative designs, top-quality materials, and decades of experience have all come together to provide superior heat dissipation with vapor chamber cooling on some of the top-tier brands.

Suffice it to say, no matter the brand, the GTX cards were designed to blow your mind. Thankfully, they’re not designed to blow your bank account, too. Affordable, killer graphics are a treat for your eyeballs when you drop the cash for a GTX 1080. But all that awesome will be worthless if you don’t give it the juice it needs. Screaming graphics come with a fairly high power need. 

Choosing a Power Supply for the GTX 1080

I could go on for days about my one true love, the GTX 1080, but I’m sure you’d like to hear about the power. After all, without a good power supply, you’ve just got an expensive paperweight. Be aware that there are several types of GTX 1080s on the market right now. Each has its own set of requirements, so be sure to check if yours is compatible with the following power supplies before purchasing.

Most GTX 1080 cards state that a 500W power supply should be good enough, but I’m of a different mind. My experience has proven that when it comes to power, you don’t want to go with the recommended. Always go higher.

Why?

Because that power supply isn’t only powering your graphics card. It needs to power a large number of components, usually all at once. You can go bare minimum and get away with it for a while, but I prefer to future-proof my rigs.

Eventually, you’ll be upgrading other parts of your computer, even if the graphics card is still good. If you happen to upgrade a component to something with a much higher power consumption than the original, suddenly that smaller power supply isn’t going to cut it. Since power supplies can be a big investment, it’s much better to get the biggest one that’s appropriate for your rig—and the future of your rig!

If this is your first time shopping for a new power supply, it can be a bit daunting. There’s a lot of information to absorb, and you don’t want to fry your PC in the process. Don’t worry though. I’ve done some of the hard work for you, testing the GTX 1080 with the following power supplies and scouring the internet for other opinions, too.

Choose something from this list for your GTX 1080 graphics card and you can’t go wrong. Just be sure your specific card and the power supply are compatible first. 

 

What Power Supply Do I Need for a GTX 1080?

Check the website for the brand of your choice for the details, but on average, the GTX 1080 graphics card needs at least a 500W power supply. This is the minimum suggested. Some brands have tweaked their version of the GTX 1080 to require less power, but I’d still go for the bigger ones.

Best Power Supplies for the GTX 1080
(+Comparison Table)

What you buy is ultimately your decision, but the following power supplies worked like a charm for my Nvidia GTX 1080 graphics card. My testing included running games such as The Witcher 3, Far Cry New Dawn, and The Elder Scrolls Online, each for about 4 – 8 hours. I also ran them through a cycle of photo editing with Photoshop and some painting with Corel Painter 2019 at the same time. These are all intense programs that push graphics cards and power supplies to the max and tend to make a PC pump out some serious heat.

I did not personally test every card listed here—only some of them—but I researched the heck out of them on your behalf. I looked for reviews from experts in the field, pro gamers, and regular users running similar rigs and software.

And now, in no particular order, my top pick power supplies for the GTX 1080.

EVGA Supernova 750 P2, 80+ Platinum 750W

This fully modular power supply has enough gusto behind it to power the GTX 1080 and everything else you can imagine. With sturdy construction and a ten-year warranty, you can trust the EVGA name to back up this impressive PSU.

This power supply comes in 650W through 1200W, but the 750W is a powerful PSU with a modest price tag. You can go higher if you want, but I truly feel that the 750 will be able to handle anything you throw at it.

A nice bonus to this PSU is how quiet it runs. It’s not silent when you’re running the most power-hungry games, but it’s definitely quieter than most power supplies this size. On low to medium draw, it’s almost perfectly silent; I was able to pull off a decent bit of gaming in the wee hours without making a lot of noise.

CORSAIR AX760, 760W 80+ Platinum Certified Fully Modular Power Supply

You can’t go wrong with Corsair AX760. When I’m looking to upgrade, I always look to Corsair first. Top-notch design, silent running, and 92% power efficiency gets me excited every time I power this baby up. The design is sexy in my blue-lit case, and I like the 7-year warranty.

The 760W is a heavy-duty power supply that can run the GTX 1080 without a hitch. I had it running triple monitors with Photoshop on one, Far Cry New Dawn on another, and watching YouTube on the third. Not even a hiccup! The case stayed cool to the touch, and I barely heard the fan on a heavy load.

This bad boy comes with trusty over-voltage and over-current protection, just in case. I love the fully modular design. Being able to detach all the cords for installation is a great bonus. Nobody wants to wrestle an octopus inside a PC case!

Rosewill Gaming 80 Plus Bronze 650W Power Supply

On the lower budget side, we have the Rosewill Gaming 80 Plus Bronze at 650W. It’s getting a bit closer to the recommended 500W for the GTX 1080, but it’s still above and beyond what you’ll need for most games.

I didn’t test this one myself, but I asked around and did see one in action at a friend’s house. While you might not be able to use this with multiple monitors and multiple power-hungry programs running, it should still treat you right if you stick with one big program at a time and one monitor.

The Rosewill Gaming 80 Plus Bronze power supply has a quiet fan on low to moderate power draws. It does make quite a bit of noise on higher draws. If noise isn’t an issue for you, this is a good trade-off, in my opinion. The operating temperature stayed fairly low and the case was cool to the touch.

It comes with a 3-year warranty, which is pretty decent for a bronze level PSU. This power supply also comes in higher watts, but if you’re going to spend that much money you might as well go with an EVGA or a Corsair instead. That is my opinion and not fact, but we’re all friends here, so I’m just going to give it to you straight.

CORSAIR RM850x, 850W, 80+ Gold Certified

Another entry for Corsair on my must-have list for GTX 1080 power supplies. This fella is meaty and powerful. With 850W and a gold rating, you’re going to get maximum power and stability. But, of course, you’ll be paying for the best, so don’t expect any big savings here.

If you need to play your games at the absolute highest settings (don’t we all?) and enjoy watching movies in high definition, this power supply will fit the bill.

A bonus for this particular card is that it was built with sound in mind. It’s big and powerful, but it’s not going to wake the dead when you power up. In fact, at low to medium loads, the fan switches off entirely. But don’t worry; it’ll stay cool even without the fans blowing.

Bottom Line on Power Supplies for GTX 1080 Cards

I can’t stress this enough: with so many manufacturers offering their own take on the GTX 1080, you need to be sure yours is compatible with the power supply before you drop the money. All the specs for you specific card should have come in the box. If they didn’t check online to make sure. There is nothing more infuriating than finding out too late that you have the wrong connectors. Power supplies are generally good to go for just about anything, but it’s best to check.

Though the average suggested power supply for the GTX 1080 is about 500W, I’d suggest going higher. Unless you’re running an incredible gaming rig with ridiculous power needs, you can stick around the 750W range and be safe. You can go as low as 650W before I’d start to worry.

But just because I think you should go higher, it doesn’t mean you have to. I know plenty of people with mid-range PC setups that stick with a 500W PSU and do just fine.

And a final word: The PC parts industry moves fast. While this list of the best power supplies for the GTX 1080 is current right now, something even better may come down the line in another few months. We’ll do our best to keep you all updated. In the mean time, we’d love to hear from you! Know an awesome power supply that keeps your GTX 1080 purring? Tell us about it!

Swooping in for our best semi-modular spot is actually a PSU that flies pretty low under the radar, the Raidmax Scorpio 535W.

I’ve actually had the chance to get hands-on experience with the Scorpio being that it was my main power supply for almost 2 years, and I still use it to this day for component testing.

Let me tell you, this thing can take a beating.

Not only does this bad boy sport a whole 535W (enough for most systems), the sheer amount of times this thing has been dropped or had things dropped on it is staggering, and it’s still chugging on.

That doesn’t mean go throw it down the stairs though.

Going for a budget build and don’t need the extra baggage? The Seasonic S12II 450 80+ Bronze comes to the rescue!

Coming in at only $45USD (that’s 10 watts per dollar!) the Seasonic S12II offers almost unrivaled reliability at a compelling price point, and 430 watts is enough for any budget or even mid-range build.

The 80+ Bronze efficiency rating may not be the greatest of all but you’ve got to cut some corners somewhere, and they sure don’t cut the corner of quality.

Seasonic is so confident in the quality of this power supply that it includes a whole 5 year warranty! Geez.

But here’s the thing:

If you’re buying a power supply for a GTX 1080 Ti, don’t buy a non-modular model.

A 1080 Ti is a top tier graphics card, one that’s meant to be paired with a top-tier power supply like one of the two mentioned above.

That being said, you don’t need a modular power supply, so it’s really up to you.

But if I was building a gaming PC with a 1080 Ti, I’d be going fully modular and 80+ Gold certified all the way!

Powering a GTX 1080 Ti Crypto Mining Rig

gtx 1080 ti mining rig

In some cases, you may be looking to use your 1080 Ti for cryptocurrency mining instead and don’t worry we’ve got you covered with the EVGA Supernova 1600 T2.

The quality of your power supply when crypto mining is absolutely detrimental to success.

Just think about how fast you’ll lose money if your PSU dies, for example. So you need something you can rely on and the Supernova T2 series doesn’t disappoint.

At 1600 watts with a mouthwatering 80+ Titanium rating, the 1600 T2 provides plenty of power for your rig and considering the 1080 Ti can hit a power draw upwards of 200 watts you’re gonna need it if you’re running a sizeable rig.

If you are running a smaller rig we suggest opting for the 1000 T2 or the 850 T2 since they provide the same great reliability as the 1600 without the extra wattage or cost.

Power Supplies: How to Make The Right Choice

Choosing the right power supply can be tricky – luckily, this video is here to help:

Types of Power Supplies

There are three different types of power supplies:

  • Non-modular
  • Semi-modular
  • Fully modular

Each type has a varying degree of customization in the sense that they have interchangeable cables, and the names pretty much speak for themselves.

Non-Modular

non modular power supply example

A non-modular power supply is generally the cheapest out of the three types because of its lack of customizability.

Non-modular power supplies come with all of their cables attached to the power supply box unable to be removed, unlike the other two types.

This, of course, means that whatever cables are there is all you have to work with.

One of the other downsides to non-modular power supplies is that since it comes with the cables pre-attached, any extra unused cables are kinda just stuck there and you’ve got to find a way to get them out of the way for cable management.

Also, many non-modular power supplies don’t come equipped with enough PCIe power cables to power higher-end graphics cards.

A good situation to pick a non-modular power supply would be for a lower budget build, or if you know for sure you have the right cables.

Luckily, most good and cheap non-modular power supplies fall under the 80+ Bronze efficiency rating which we’ll talk about later.

Semi-Modular

semi modular power supply example

Semi-modular power supplies are like the best of both worlds when it comes to power supplies, they include the main cables that every motherboard and (almost) every graphics card needs.

This includes the 24-pin ATX power connector for the motherboard, the 4+4-pin CPU power connector, and a 6+2-pin PCIe power connector.

The modular portion comes in with the optional included cables.

Semi-modular power supplies tend to have 3 optional peripheral slots and a second PCIe power connector slot in case your graphics card needs more than 8-pin power.

These optional slots can be fitted out with SATA power connectors for HDD and SSD power, or Molex connectors for various power use cases.

Semi-modular power supplies are what we recommend for any build since they’re often cheaper than their fully modular counterparts as you go up the efficiency ladder, while still offering just as much ease of use and reduced cable hassle.

Fully-Modular

fully modular power supply example

Finally, we reach the fully-modular power supply options.

Fully-modular power supplies are for the user that absolutely needs maximum possible customization because with a fully-modular power supply, you can remove every cable from the power supply as you wish.

Unfortunately, this does mean that the extra engineering that goes into these power supplies can be explicitly seen in the cost as fully-modular power supplies cost a helluva lot more than the other two types.

This does come with one added benefit, however, in that the cost also reflects their reliability.

We wrote an awesome guide abou whether or not you need a modular power supply, which you can read by clicking here.

Power Supply Wattage

A power supply’s wattage is fairly self-explanatory.

Whatever wattage your PSU is rated for, is the maximum power output it can sustain, so don’t go pairing a 250W PSU with a system drawing 300W.

Don’t go thinking you can pair a 400W power supply with a system drawing 400W though, because any fluctuation that might put that power draw above your PSU’s limit can fatally damage your components.

Efficiency Rating

The efficiency rating of a power supply is just what the name implies; a rating on how power efficient a power supply is.

In short, the higher the efficiency rating on your PSU, the more electricity makes it from the wall to your computer as opposed to being lost to heat or other outlets.

For a more in-depth look, check out this article we wrote that’s all about power supply efficiency ratings.

How Much Power Does the GTX 1080 Need?

It is a very common rookie mistake to ignore the importance of the power supply unit (PSU) when building or buying a computer. They are almost always preoccupied with the CPU or GPU, completely ignoring the PSU.

These consumers sometimes end up having a complete system with insufficient power, and as a result, they encounter system failures, or worse, burning their shiny new components because of a cheap power supply.

a GTX 1080 brand new in box

As all experienced PC gamers would advise, “Never cheap out on the PSU”.

For a power-hungry GPUs such as the GTX 1080, choosing the right power supply is just as important as choosing the CPU or motherboard.

It may not be as shiny as your RGB components and peripherals, but your power supply plays an important role in the overall performance of your computer, as it is the one bringing the juice to all the components in order for them to work.

In this article, we will discuss the power consumption of this popular GPU and its ideal power supply requirements in different cases.

Contents

So How Much Power Does a GTX 1080 Use?

As per Nvidia’s official website, a GTX 1080 has a power consumption of 180W and has a recommended system power of 500W. It also uses one or two 8-pins or 6+2 pins PCIe connectors depending on the GPU brand.

Although this may still vary as there are different variants of GTX 1080 available in the market today. Some variants of GTX 1080 may require more PCIe connectors or power because of some additional features such as being factory overclocked.

Is 450 Watts Enough for the GTX 1080?

Yes and No. While a gaming PC with a GTX 1080 might work with only 450W, it is not ideal to run your PC with very low system power and we definitely won’t recommend this for a GTX 1080 setup.

Although 450W should be enough to power the 1080, remember that this GPU alone consumes up to 180W, not to mention the power consumption of your other hardware such as the CPU, drives, memory, and so on.

In addition to that, always keep in mind that the recommended system power of running a GTX 1080 is at least 500W, so it is best to keep your system power within that range, or better yet, more than what is required for headroom for future upgrades.

Anyway, for the sake of this discussion, we’ve tried analyzing the power consumption of a desktop PC using the Seasonic wattage calculator.

This setup is composed of very basic components and peripherals along with GTX 1080 to determine whether a 450W PSU is enough for GTX 1080.

Main Specs Used:

CPUMemoryGPUStorageFansPeripherals
Intel Core i5 104002 x 8GB DDR4GTX 10801 x SSD + 1 x 7200RPM HDD6 x 120mm fans (2 front, 2 top, 1 rear, plus 1 for the CPU heatsink)Gaming Keyboard and Gaming Mouse

Power Consumption Results:

Load WattageRecommended PSU Wattage
404W454W

After running the wattage calculator, we’ve found out that the total power consumption of this particular setup at full load is only 404W, enough for a 450W PSU… or is it?

Since power supplies are not at all times efficient, we cannot be sure that a 450W power supply can always deliver at 100%, that is why it is highly recommended to go beyond the recommended system power.

a 1080 after being unboxed before installation

Is 500W Enough Power for this GPU?

Based on the official Nvidia’s website, 500W is the recommended system power for a GTX 1080 which means it should be enough to power up your system.

But we have not taken into the account the other components and peripherals that you may have such as a CPU, multiple drives, RGB strips and fans, multiple RAM sticks, and so on.

So using the same wattage calculator, let us tweak the components from the previous one and determine if 500W is ideal for the GTX 1080.

Main Specs Used:

CPUMemoryGPUStorageFansPeripherals
Intel Core i5 104002 x 8 GB DDR4GTX 10801 x SSD + 2 x 7200RPM HDD6 x 120mm fans (2 front, 2 top, 1 rear, plus 1 for the CPU heatsink)Gaming Keyboard and Gaming Mouse

Power Consumption Results:

Load WattageRecommended PSU Wattage
415W465W

Based on the output above, a 500W PSU should be enough for the GTX along with basic components.

If you are planning to use a 500W PSU for the GTX 1080, just always keep in mind your future upgrades, as this may affect the total load wattage of your entire system and the 500W is no longer enough.

Can a 550W PSU Run a GTX 1080?

Definitely. A 550W PSU is more than enough to run a GTX 1080. Not only is this PSU enough, but you also have headroom for future upgrades.

With a 550W power supply, you can also use a better CPU along with the GPU, as well as additional accessories and peripherals.

Below is an example of a more power-hungry system alongside the GTX 1080, let’s see how a 550W power supply would perform under this type of setup.

Main Specs Used:

As you can see from our example above, a 550W PSU should be enough to run a GTX 1080.

Also, we’ve added an additional M.2 SSD, an AIO cooler, LED strips, and a fan controller device. The load wattage for this kind of setup is only at 486W with a recommended PSU wattage of 536W.

What About Using a 600W PSU?

Since a 550W PSU is enough for the GTX 1080, there’s really no reason why a 600W PSU will not work.

600W should be more than enough to power up an entire system that contains a GTX 1080. So this time, let’s take a different approach to how we calculate the capabilities of a 600W PSU in terms of delivering power to a GTX 1080 gaming setup.

Main Specs Used:

CPUMemoryGPUStorageLiquid CoolerFansPeripheralsOther Accessories

Power Consumption Results:

Load WattageRecommended PSU Wattage
491W541W

Note that we changed the CPU to an overclocked Ryzen 7 3700X and NZXT Kraken X72 360mm AIO.

As you can see, there’s still lots of headroom for 600W as the total wattage is only at 491W and recommended PSU wattage at 541W, even for an overclocked Ryzen 7 3700x.

So if you have a 600W PSU right now and are planning to buy a GTX 1080, you have nothing to worry about.

Is 650W a Good Idea to Run a GTX 1080 or is it Overkill?

Since it is obvious enough that a 650W PSU can run a GTX 1080 with ease, let’s take another approach on testing it.

This time, let’s see if a 650W PSU is capable of running a 2 x GTX 1080 at SLI configuration.

Main Specs Used:

CPUMemoryGPUStorageFansPeripherals
Intel Core i7 107004 x 8GB DDR42 x GTX 1080 SLI
1 x M.2 SSD + 1 x 7200RPM HDD8 x 120mm fans (3 front; 3 top; 1 rear; 1 for CPU heatsink)Gaming Keyboard and Gaming Mouse

Power Consumption Results:

Load WattageRecommended PSU Wattage
594W644W

In this kind of setup, we changed the CPU to Intel Core i7 at stock speed and removed the water cooling and other devices.

The results show us a 594W load wattage with a recommended PSU wattage of 644W.

In theory, a 650W should be enough to run this setup considering the load wattage is only at 594W. But there are other things to consider such as the efficiency of the power supply and the total number of PCIe connectors.

The Bottom Line: What Wattage PSU Would you Recommend?

Based on the sections above, the safest and the most recommended PSU wattage for GTX 1080 is 600W.

Even for the most experienced users, 600W is the sweet spot for a GTX 1080 since there may be some upgrades in the future, that may need some additional system power.

This way, you don’t have to worry now or in the future, whether or not your PSU can handle the overall power requirements of your gaming PC.

Frequently Asked Questions (FAQs)

What Should I be Looking for When Choosing a PSU for this GPU?

While choosing a specific brand for PSU is broad, there are some guides that you may want to consider in choosing the best PSU for your needs and budget.

The first one is the 80+ certification. Ideally, you would want to get a PSU with at least a 80+ Bronze certification.

a Seasonic SSR-600TL PSU

We have written reviews on the best PSUs for the GTX 1080 currently which may be of some help to you.

What is the Difference Between GTX 1080 and GTX 1080 Ti?

Many people are confused about NVidia’s line of graphics cards, specifically to their Ti and non-Ti cards, particularly, the GTX 1080 and GTX 1080 Ti. So what exactly are the differences between both cards?

Both cards are under the same GPU Pascal architecture and have the same standard memory configuration of GDDR5X, there are a lot of differences between the two cards in terms of performance.

Below are the specs of both cards.

GTX 1080GTX 1080 Ti
GPU ArchitecturePascalPascal
Frame Buffer8 GB GDDR5X11 GB GDDR5X
Memory Speed10 Gbps11 Gbps
Boost Clock1733 MHz1582 MHz
Cuda Cores25603584
Memory Interface Width256-bit352-bit
Memory Bandwidth320 GB/sec484 GB/sec

As you can see from the quick specs table above, the GTX 1080 Ti has a clear advantage except for boost clock.

But it shouldn’t affect the overall performance that much since there are still other factors that affect the GPU’s raw power, such as the Cuda cores, memory bandwidth, and VRAM.

With that being said, Nvidia’s Ti cards are faster than the non-Ti version, and are usually more expensive.

This is to cater to the consumers that want more options when choosing the right type of GPU.

Is the GTX 1080 Still Good Today?

The answer to this is yes the GTX 1080 is still good today. It is still after all of these years able to handle 1080p at an impressive 80 FPS even for the most demanding triple-A games at high settings. Here

Nvidia GeForce GTX 1080 review - Hardware Setup | Power Consumption

Hardware Installation

Installation of any of the Nvidia GeForce cards is really easy. Once the card is seated into the PC make sure you hook up the monitor and of course any external power connectors like 6 and/or 8-pin PEG power connectors. Preferably get yourself a power supply that has these PCIe PEG connectors natively as converting them from a Molex Peripheral connector anno 2016 is sooo 2008. Purchase a proper power supply, ok?
 

 

Once done, we boot into Windows, install the latest drivers and after a reboot all should be working. No further configuration is required or needed unless you like to tweak the settings, for which you can open the NVIDIA control panel.
  

 
Power Consumption

Let's have a look at how much power draw we measure with this graphics card installed. The methodology: We have a device constantly monitoring the power draw from the PC. We stress the GPU to the max, and the processor as little as possible. The before and after wattage will tell us roughly how much power a graphics card is consuming under load. Our test system is based on an eight-core Intel Core i7-5960X Extreme Edition setup on the X99 chipset platform. This setup is overclocked to 4.40 GHz on all cores. Next to that we have energy saving functions disabled for this motherboard and processor (to ensure consistent benchmark results). We'll be calculating the GPU power consumption here, not the total PC power consumption.

Measured Power Consumption

Mind you, the system wattage is measured at the wall socket side and there are other variables like PSU power efficiency. So this is an estimated value, albeit a very good one. Below, a chart of relative power consumption. Again, the Wattage shown is the card with the GPU(s) stressed 100%, showing only the peak GPU power draw, not the power consumption of the entire PC and not the average gaming power consumption.

 
 
Power consumption TDP in KWhKWh price2 hrs day4 hrs day
Graphics card measured TDP0,1840,230,080,17
Cost 5 days per week / 4 hrs day€ 0,85
Cost per Month€ 3,67
Cost per Year 5 days week / 4 hrs day / €€ 44,01
Cost per Year 5 days week / 4 hrs day / $$ 58,10

Here is Guru3D's power supply recommendation:

  • GeForce GTX 1070 / 1080 - On your average system the card requires you to have a 600 Watts power supply unit.
  • GeForce GTX 1070 / 1080 SLI - On your average system the cards require you to have a 850~900 Watts power supply unit.

If you are going to overclock your GPU or processor, then we do recommend you purchase something with some more stamina.

There are many good PSUs out there, please do have a look at our many PSU reviews as we have loads of recommended PSUs for you to check out in there. What could happen if your PSU can't cope with the load is:

  • Bad 3D performance
  • Crashing games
  • Spontaneous reset or imminent shutdown of the PC
  • Freezing during gameplay
  • PSU overload can cause it to break down

Let's move to the next page where we'll look into GPU heat levels and noise levels coming from this graphics card.

Buyers Guide

In order to get the best PSU for your GPU, you’d need to look for a couple of things in it and take multiple things into considerations that are mentioned below.

Ignoring these things will lead to a PSU that wouldn’t work up to what you’ll expect. Also, it will create problems in the future for you and can, severely, damage your GPU as well.

Quality

Quality is something that should never be overlooked as ignoring it can lead you to counter a ton of problems in your life. 

If you opt to save money and go for a cheap PSU then it might save you some bucks in short term, but it can cost you a lot in the long run by damaging your PC’s component and making you invest a lot more than what you were supposed to if you had picked a top-quality PSU. 

A quality PSU can give a long-lasting life to your computer, so we recommend you to do your homework before going to buy one. 

Wattage

Another important thing that should be taken into consideration is the wattage of the PSU that your system requires. It is really necessary to look at the wattage of the power supply as not every wattage of PSU can fit your PC’s requirement. 

This is kind of a situation where more is always not the best. However, a PSU is able to provide enough power under heavy load to all of the components.

Furthermore, the majority of the PSUs hit their peak efficiency from 40% to 80% of the power supply’s max capacity. And we recommend building to about 60% of a PSU’s capacity to be in the sweet spot for efficiency and leaving enough room for future upgrades.

Efficiency

The efficiency of a power supply is very important because a higher-efficiency one tends to give better performance, generating less heat, and wasting less power; making the PSU make less fan noise. 

A PSU that has an efficiency rating of 80% gives 80 percent of its rated watt in the form of power to the system and loses the other 20 percent as heat. Furthermore, there are several tiers of 80+ ratings that include bronze, silver, gold, and platinum; and the PSUs have been divided into these tiers due to their performance and other aspects. 

Cable Management

If you’re a fan of aesthetics then you won’t be pleased to see your PSU carry the huge stack of unused cables and struggling to hide them inside the case, which later on can be interfering with the airflow in smaller cases. 

We would recommend the modular PSU for GTX 1080 because they are the popular ones in the market; allowing you to effortlessly organize your power connections, and have many pros as compared to the standard ones. 

Trusted Brands

A PSU from a trusted and widely known brand can give you a lot more great performance than the local and cheap quality ones. It is not always good to save money when you’re prone to get something fishy that drives you to damage yourself in the future. 

We suggest going for a branded power supply as they are more trusted and offer the performance that you expect. 

Also, trusted brands give a warranty so if you run into any issue, they will help you out with that. 

FAQs

Conclusion

After going through this guide, you’ll be able to make proper decisions before buying a power supply for your GTX 1080 to enhance the performance and experience. 

It’s really important to look for a powerful PSU that really delivers what it promises because it plays a huge role in your PC. Not every power supply matches your system; neither a random picked one can fit and deliver as you expect. 

If you’ve found what you were looking for, do let us know about your input in the comment section as well.
