Best Power Supply for GTX 1080 – Avoid One Big Mistake. What power supply do i need for a gtx 1080

The only thing we didn’t like about this power supply was the smaller distance between the peripheral connectors compared to the competitors on the market. In addition, it will be much better if it has a short response on smaller rails.

Best Power Supply for GTX 1080 Reviews

GTX 1080 is the most powerful graphics card released by Nvidia. It can run any game with top quality graphics and high definition sound effects. It is considered by gamers to be the most reliable and visually effective GPU.

You need a reliable power source to use these features. Low power levels can overload and damage devices. On the other hand, too much power means a waste of money.

Finding the perfect power supply that will improve the performance of your gtx 1080 can be quite a challenge. That’s why we reviewed the 7 best power supplies for the GTX 1080.

What is the Best Power Supply for GTX 1080?

  • Perfect high temperatures: Corsair CX CP-9020102 power supply
  • Best silence: the CORSAIR HX750i series power supply
  • Best energy efficiency: EVGA 220-P2-0650-X1 power supply
  • The best compact: the Seasonic FOCUS Plus SSR-750PX power supply
  • Zero noise: Thermaltake Smart BX1 power supply
  • Best compact size: the Corsair RM750x power supply
  • Best budget: FOCUS Plus 550 Gold SSR-550FX seasonal power supply

Finding the right power supply is very important as the wrong power supply can cause irreparable damage to your devices. Therefore, check out these key factors when choosing the best PSU for the gtx 1080.

Power Supply Outlets

It just depends on the type of outlet your power source is using. Few sources have a single input / output. Some others provide multiple I / O.

For large configuration, you will need multiple I / O which can run in an AC unit. If your setup is small, one outlet is enough.

Power Supply Types

Currently, full, half and non-modular power supplies are available. Each type provides different functions. Non-modular power supplies are the cheapest and come with all cables included with the power box.

Semi-modular power supplies are great because they are cheaper than fully modular. But they provide the same ease of use and customization features. If you need maximum cable customization, go for fully modular as every cable of this type is interchangeable.

Power Supply Wattage

Most PCs do not require a large power supply. Therefore, take into account the fact that a larger power supply presents a risk of overkill and may damage your equipment. A 500W-650W power supply will be more than enough for most systems.

Form Factors

The main aspect ratio of each processor is ATX / Eps or SFX / SFF.

SFX or “smaller aspect ratio” is designed to make smaller computers run smoothly and efficiently without crashing. On the other hand, ATX are standard size computers and can be used with almost all CPUs.

Efficiency Rating

The higher efficiency of the power supply means that it effectively minimizes power loss. It also reduces less electricity loss in the form of excess heat. Therefore, check the performance rating of the power supply before purchasing.

Read on to find the most compatible power supply for your GTX 1080.

You need a reliable power source to use these features. Low power levels can overload and damage devices. On the other hand, too much power means a waste of money.

Why the GTX 1080 Is Amazing

Before we dive into some killer power specs for the GTX 1080, you need to know why this card is still a favorite among serious gamers. The GTX line of graphics cards has been the epitome of gaming prowess for many years. It can be found in many different brands, but they are all essentially the same.

Thanks to the Nvidia Pascal architecture, there is not a single game that can slow down 1080. Pump your games to high and very high graphics settings and stick to your pants. They offer three times the performance than all previous generations of graphics cards. They can handle even the most difficult and graphically intense VR games.

With so much going on in these elegant and sexy cards, the heat should be a real problem. But not with the GTX 1080. Innovative designs, premium materials and decades of experience have come together to provide excellent heat dissipation with vapor chamber cooling in some of the top brands.

Suffice it to say, no matter what brand the GTX cards are designed to blow up. Luckily, they aren’t meant for blowing up your bank account. The inexpensive, deadly graphics are a feast for the eyeballs when you spend your money on the GTX 1080. But it will all be worthless if you don’t give it the juice it needs. Screaming graphics have a fairly high energy requirement.

Choosing a Power Supply for the GTX 1080

Power supply. Close-up. Yellow fan blades

I could talk about my one true love, the GTX 1080 for days, but I’m sure you’d like to hear about power. After all, without a good power supply, you just have an expensive paperweight. Please note that there are several types of GTX 1080 available on the market today. Each has its own set of requirements, so check that yours is compatible with the following power supplies before purchasing.

Most GTX 1080 cards say a 500W PSU should do the job, but my opinion is different. My experience has shown that when it comes to power you don’t want to go with the recommended one. Always go higher.

Because this PSU doesn’t just power your graphics card. It has to power a large number of components, usually all at once. You can go to the bare minimum and get away with it for a while, but I’d rather secure my kits for the future.

Eventually, you’ll update other parts of your PC, 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 this smaller power supply won’t reduce it. Since power supplies can be a large investment, it’s much better to buy the largest one that’s right for your kit – and the future of your kit!

If this is your first time purchasing a new PSU, it can be a bit daunting. There is a lot of information to digest, and you don’t want to fry your computer in the process. But don’t worry. I’ve done some of the hard work for you testing the GTX 1080 with the power supplies below and scouring the internet for other reviews.

Pick anything from this list for your GTX 1080 graphics card, and you can’t go wrong. Just make sure your specific card and power supply are compatible.

Buyers are very impressed with the Corsair CX series. From price to material quality, everything is top notch. Users recommend that you use the power supply with the cables attached to it, rather than the one that came with the old power supply. This will ensure compatibility and smooth operation

Raidmax Scorpio 535W

Semi-Modular Power Supply

This power supply is half the price above, but still easy to keep cables tidy, has plenty of power, and is 80+ Bronze certified.







Swooping at our best semi-modular site is actually a power supply that flies quite low under the radar, the Raidmax Scorpio 535W.

Actually, I had the opportunity to get hands-on experience with the Scorpio as it was my main power supply for almost 2 years and I still use it today for component testing.

Let me tell you, this thing can beat.

Not only is this bad boy a whole 535W (enough for most systems), but the sheer number of times this thing has been dropped or has fallen onto it is staggering and it continues to crash.

It doesn’t mean, however, that you have to throw it down the stairs.

Please don’t do this…

Seasonal non-modular power supply

Seasonic S12II

Non-Modular Power Supply

If for some reason you need a regular, non-modular power supply, this is our best choice. This is fine for builders on a budget, although I don’t know what your budget is if you can afford 1080 Ti.







Are you going to a budget construction site and you do not need additional luggage? Seasonic S12II 450 80+ Bronze comes to the rescue!

Priced at just $ 45 (that’s 10 watts per dollar!), The Seasonic S12II offers near unparalleled reliability at a great price, while 430 watts is enough for any budget or even mid-range build.

The 80+ Bronze’s performance rating may not be the best of all, but you need to cut corners somewhere, and they certainly don’t cut corners when it comes to quality.

Seasonic is so confident in the quality of this PSU that it comes with a full 5-year warranty! Jesus.

But here’s the thing:

If you are purchasing a power supply for the GTX 1080 Ti, please do not buy a non-modular model.

1080 Ti is a top tier graphics card to be paired with a top tier power supply like one of the two mentioned above.

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

But if I were to build a gaming PC with 1080 Ti I would be fully modular and certified with 80+ Gold!

The bonus for this particular card is that it was built with sound in mind. It’s big and powerful, but it won’t wake the dead when you turn on the power. In fact, at low to medium loads, the fan turns off completely. But do not worry; it will stay cool even without blowing the fans.

Is 500W Enough Power for this GPU?

According to the official Nvidia website, 500W is the recommended system power for the GTX 1080, which means it should be enough to power your system.

But we didn’t take into account other components and peripherals such as CPU, multiple drives, RGB strips and fans, multiple RAM, and so on.

Using the same power calculator, let’s adjust the components from the previous one and determine if 500W is perfect for the GTX 1080.

Main Specifications Used:

Processor Memory GPU Storage Fans Peripherals
Intel Core i5 10400 2×8 GB DDR4 GTX 1080 1 x SSD + 2 x 7200 rpm HDD 6 120mm fans (2 front, 2 top, 1 rear and 1 for CPU heat sink) Gaming keyboard and gaming mouse

Energy consumption results:

Load power Recommended PSU power
415W 465W

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

If you plan to use a 500W PSU for the GTX 1080, always be aware of future updates as this can affect the total system load power and 500W is no longer enough.

Can a 550W PSU Run a GTX 1080?

Definitely. The 550W power supply is more than enough to run the GTX 1080. Not only is this power supply enough, you also have plenty of space for future upgrades.

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

Below is an example of a more energy-intensive system alongside the GTX 1080. Let’s see how a 550W PSU would handle this type of setup.

Main Specifications Used:

Processor Memory GPU Storage Liquid cooler Fans Peripherals Other accessories
Intel Core i7 10700K 2x8GB DDR4 GTX 1080 1 x M.2 SSD + 1 x SSD + 2 x 7200 rpm HDD Master MasterLiquid Pro 120 cooler 6 120mm fans (3 front, 3 top) Gaming keyboard and gaming mouse LED strips and fan control device

Energy consumption results:

Load power 486W
Recommended PSU power 536W

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

We also added an additional M.2 SSD, AIO cooling, LED strips, and a fan controller. The load power for this type of configuration is only 486 W with the recommended PSU power of 536 W.

1080 before installation

This is a situation where more is not always the best. However, the power supply is able to provide sufficient power under heavy load to all components.


After reading this guide, you will be able to make the right decisions before purchasing a GTX 1080 PSU to increase your performance and experience.

It’s really important to look for an efficient power supply that really does what it promises as it plays a huge role in your computer. Not every power supply is suitable for your system; none randomly selected can fit and deliver as expected.

If you found what you were looking for, also let us know about your entry in the comments section.

This 80+ Gold certified power supply is an absolute monster. With its fully modular design, the RM650x makes cable management child’s play and has more than enough power to run not one but two GTX 1080 Ti simultaneously.

Best Power Supply For GTX 1080 Comparison Table

1. Corsair CX Series 550 Watt Power Supply – Best Overall

Corsair units are inexpensive and make an excellent choice for entry-level computing and desktop systems. They are available in many power configurations and have features that are easily found in premium power supplies.

Corsair CX 550 W series

When you think of a system so cheap, you think it would be cheaply produced as well. However, this is not the case with this Corsair unit. It is characterized by excellent workmanship and a low error assessment.

The cables of this unit are non-removable and fully sheathed (which solves the problem of their falling apart on other models), it has a PCI express connector, and the cables are long enough.

This unit is equipped with a 120mm fan for quiet operation, almost equivalent to fanless systems. It also provides great energy savings during use. It also supports the latest ATX12V and is backwards compatible with ATX12V 2.01 systems. It also offers universal AC input and overcurrent / voltage / short circuit / power protection to ensure the safety of system components.

  • Reliable
  • Inexpensive
  • Short circuit protection
  • Backward compatible
  • Low error rating

2. Seasonic Prime 600 Watt Power Supply – Premium Pick

The Seasonic 600 WT has no fan making it a silent addition to your gaming system. This model is low power consumption, supports two EPS slots, supports multiple GPUs, and has four PCIe slots. All of this together allows you to operate an advanced and ingenious gaming system.

Seasonal Prime 600

It has also been awarded the highest Titanium performance certification, with 94% efficiency at 50% load, all with the complete absence of a fan. This shows that it has the highest level of output power on the fanless market, which makes this model stand out more than ever before.

Another great thing about this model is that it is Multi-GPU, which means you can use up to two graphics cards. However, please note that you cannot use two GTX 1080s with two graphics cards depending on their power output. Graphics cards produce too much power, which means you can’t handle two cards on a 60W PSU at the same time.

The only drawback is its price. However, any power supply in this category with this caliber will have this problem. If you are looking for a power supply for a heavily loaded computer (gaming, photography, business, recording studio etc) then this is the system you want to invest in.

  • No fan
  • Quiet
  • Multi-GPU
  • It has the highest performance title of 80 Plus Titanium
  • Low energy consumption
  • Fully modular
  • 600 W capacity

3. Thermaltake Smart 700W Power Supply – Budget Pick

If you are looking for a device that saves energy, this is for you. It saves up to 86% energy and can operate and adapt to any mainstream. It also has the 80 PLUS Standard certificate. It has a wattage of 700W and should have more than enough wattage to break through most gaming PCs. The low price is also very attractive to many buyers and makes it one of the best power supplies for the GTX 1080.

How To Choose The Right Power Supply

It shows up for every type of gamer, businessman, and even recreational people, there are plenty of options to choose from. When choosing a power supply, however, remember that choosing the wrong one can cause irreparable damage to you, your electronics and your household (even causing a risk of fire or blowing up the fuse box), build a computer or control the configuration. Remember: multiple power supplies can run on multiple machines, so the possibilities are endless depending on your needs and intentions.

Style of Power

Consider what type of power your chosen power source uses and how it best suits your needs. Some power sources have one I / O while others have multiple. If you’re running a larger setup, you’ll most likely be looking for a multi-input / output power supply that plugs into a surge protector or AC outlet.

If you’re running a smaller setup, a single AC outlet (or commonly known as a wall outlet) should be fine. However, if you’re running a much larger setup (for example, in a business or hospital), you’ll need to use a power supply with more than one output.

Don’t Just Go For The Biggest One You Can Find

Even if you think bigger is better, that’s not always the case. Huge power supplies are usually not needed for most PCs. Remember – your system will not be used all the time and will not run at peak performance all the time which means that if you go for the largest PSU it will probably be overkill and it can definitely burn out your hardware. You can choose 500W-600W, which will be idle at 80W and still be as effective in your setup as 1200W. Remember that; the higher the voltage, the more stress it will bring.

If you’re wondering what voltage is right for your computer setup, there are many online tools out there to help. One of them is the EVGA power meter (it will ask how many disks, GPU, CPU and if you are overclocking it). If that doesn’t work, another good alternative is vbutils which are a bit more specific with your computer’s components. They will give you a base value and advise you not to exceed it. Remember – most PCs don’t need anything above 600W, so even increasing the power to 650W is overkill.

GTX 1080 power supply


Now that you know what the wattage is, the next step is to consider the layout and size of your PSU. Of course, there are many different aspect ratios, but each aspect ratio falls into the ATX / Eps and SFX / SFF categories.

SFX was introduced in 1997 and is a “smaller aspect ratio” and is intended for smaller PC configurations. However, this model was introduced for less powerful PCs – for example: general consumers and offices. Recently, however, they have been competing with ATX and have become more popular due to their increased power output. While they can’t compete with a full-sized ATX, they can still accommodate smaller PCs to keep them running smooth and efficient without interruption.

SFX power supplies will most likely be more expensive than ATX power supplies (even at the same level and power). It is recommended that you just use one SFX on your computer if your case even requires it. However, if you are able to include more than one SFX in your setup, it is recommended that you purchase an ATX to SFX adapter (or even an ATX only at this point) to save energy and power. This way, there is no risk of overloading your computer.

This bad boy has reliable overvoltage and overcurrent protection, just in case. I love the fully modular design. The ability to detach all wires for installation is a great bonus. Nobody wants to wrestle with an octopus in a computer case!

How Do I Know if My Power Supply is Going Bad?

When your power supply fails, you may notice that your computer freezes too often, you hear noises from the PCU case, or a random blue screen appears from time to time.

To test the power supply, first make sure the power supply switch is on and the power cord is secure. Try a different power cord to eliminate the possibility of damaging the cord. Check internal connections to the computer. Remove all external connections to the computer, except for the graphics card and boot disk.
