EVGA Supernova 750 P2, 80+ Platinum 750W

Best Rated PSU For GTX 1080

SPECIFICATIONS

Brand:EVGA | Wattage:750W | Design:Full Modular

EVGA is one of the world’s leading manufacturers of high-quality power supplies. But guys, this supreme performance comes at a high cost, but in the end, I don’t think we must ever bargain on a power supply.

So, for me, EVGA has been the all-time best high-end and premium power supply for GTX 1080. Now I am not stating that it is one of the best power supplies out there, but guys, it delivers some of the best performance that is indeed worth every penny.

Previously I used a power supply for n=my 1080, and it kept crashing repeatedly. Disappointed by the performance of my power supply, I went on to purchase EVGA Supernova, and by then, my gaming experience had been changed for good.

I was able to play Fortnite for 2 hours without crashing immediately after the replacement, which I could not do previously. It would usually crash after about 15-20 minutes. The next day, I played a few hours of Subnautica, followed by Elite Dangerous. There were no mishaps.

Let’s start with the overall appearance. The PSU has a black matt appearance that I initially found appealing. Furthermore, I believe the build is sturdy and will last a long time for me.

The second feature I appreciated was the length of the cords. Because this power supply is totally modular, the provided wires are ridiculously long. And, as far as I can tell, they can last as long as your PC case. However, some users may not have enough space to accommodate such long wires, which may be a disadvantage.

Even though the cables are long, the primary power supply cable isn’t as long as I would have expected. For example, connecting the entire setup to the power source proved complicated and time-consuming.

Furthermore, I don’t think any of you would need to go out and buy cables individually because they come with many. In addition, I liked how the cables were encased in a net.

Also, everyone had access to cable labels, so I doubt anyone would have difficulty sorting them. I completed the full setup in approximately two hours, and the fit and finish were flawless.

I then tried it on a few different tests. I initially tried gaming over this one to check if it reported any faults or not. Surprisingly, there was nothing to be upset about.

Furthermore, the PSU made no unusual noises during the procedure. Power supplies generally produce a lot of noise, but this one was silent even while running at full capacity.

There were only two minor flaws I could detect with this power supply. One thing is that the manufacturers could have made the power source wire and cord a little longer and of higher quality.

So, don’t hold back on your PSU, fellows. It’s an investment in your stability and pocketbook because you’ll have to replace it eventually.

Staff Pick

CORSAIR RM850x, 850W

Powerful PSU For GTX 1080

SPECIFICATIONS

Brand:Corsair | Wattage:850W | Design:Full Modular

If you guys know me well, you all might know how much of a huge fan I am of Corsair. And, of course, I had to share my powerful and most favorite Corsair power supply with you. So, the RM850x is one of the best power supplies for GTX 1080, according to the editor’s choice.

From the appearance, it looks like its other siblings, the rm650x and the 750x. But guys, in the performance, it is way superior to any other variants available in the same Corsair series. It has this black color finish, and there is not much to tell about the visual appearance of this power supply.

So, last year I purchased this power supply for my wife’s 3090, and this year it works as new as I have bought it today. So when I was building myself a system, I thought, why not get the RM850x.

Overall I loved this PSU because of many reasons. But the main reason behind vouching for this PSU was that it is completely modular, whisper quiet, and of course, comes with every connector you could think of.

First of all, I loved how it had these two types of CPU connectors. I had rarely seen such connectors arrive with any of the high-end PSUs out there. This allowed me to attach the PSU to a motherboard through an 8pin and 4pin CPU connector.

And guys, if you are an overclocking enthusiast just like me, then this PSU will take your gaming experience to the next level. Nothing disappointed me here except for the plastic wraps attached to the end of the cables.

While the installation itself was pretty simple, bending these cables with that wrap was a hassle. And not only this, but the wraps actually restricted me to not twist or curling the cables inside the case too. But that’s a minor drawback, and I didn’t mind that.

Now, built-in cables were also impressive with this PSU. The SATA cables had many ports on one cable. This also allowed me to chain the cables. But one thing I would like to highlight here for the manufacturers is that they must label each port so installation would be much simpler.

I individually tried and tested all of the cables that came up with this PSU for quality assurance. As you all know, there is something about modular PSUs that I couldn’t resist, and I fall for them every time.

Okay, for the performance part, I would say, guys, it’s Corsair; what else could you expect from it? The performance was just mind-blowing! There were no crashes, glitches or even blackouts.

The noise levels, even under heavy load, were somewhat bearable. There were some electrical hums, but then the noise was minimal overall and didn’t even bother me.

If I have to give my honest opinion about this PSU, I would say just grab it! The PSU has awesome performance and is silent most of the time. I do know I just came with a power connector for DVD, but then guys, I expect it to cover every

REASONS TO BUY

Completely modular

Extremely quiet

Highly efficient

Remains cools

REASONS TO AVOID

Cables are a bit flimsy to arrange

WHY YOU SHOULD CHOOSE THIS PSU?

The Corsair RMX is one of the most powerful PSUs with silent operations and is highly efficient. The cables are a bit flimsy and are a hassle to arrange inside the case, but guys, the performance is top-notch; what else do you want?!

Seasonic SSR-600TL

Best PSU For GTX 1080

Best PSU For GTX 1080 Editor’s Pick

SPECIFICATIONS

Brand:Seasonic | Wattage:600W | Design:Full Modular

Ever thought you could just get a dead silent PSU that never has a single sound to it. Yes, guys, such PSU exists, and these are known as Fanless PSUs. Seasonic is one of the best manufacturers of PSU worldwide; it has also launched its fanless PSU.

Many gamers and content creators have found the Seasonic SSR-600TL one of the silent PSUs for the GTX 1080, aka the power-hungry card. It does have some advantages as well as some drawbacks that we are going to discuss in the later part of this review.

The appearance of this PSU is just like those usual power supplies we see. Like it is all black, it does have not some but a lot of poked holes, which will aid in the airflow.

Installation was a breeze; it didn’t have anything technical to it. I liked how the unit was so light in weight compared to the previous one I had in my system. I am not fond of packing many cables into the pc case, and here I was glad that I had to use fewer power cables and not many of them.

Plus, the cables were long enough to accommodate them comfortably all around the pc case. Additionally, they were not flimsy and were flexible, so I could bend or twist them wherever I wanted. This is all because of the modular design of this power supply, and everything made sense.

I tried running his PSU under load while playing Roblox for at least 4 hours, and no weird noise was reported. However, I would not recommend this PSU for overclocking because it runs hot under extreme load.

REASONS TO BUY

Dead silent

Fully modular

Whooping 600wattage

No coil whining

REASONS TO AVOID

Expensive

Not for overclocked systems

WHY YOU SHOULD CHOOSE THIS PSU?

The Seasonic Prime 600 is awesome. It is expensive, but its powerful performance is worth every penny. But then, guys, if you are thinking of overclocking it, consider using an aftermarket cooler with this one.

Best Pick

Corsair SF600 Platinum

Best Fully Modular PSU For GTX 1080

SPECIFICATIONS

Brand:Corsair | Wattage:600W | Design:Full Modular

As you already know, I am a huge Corsair fan, so I had to include another Corsair pick in my today’s list. But this one is for those of my fellows who want the same performance as Corsair high-end variants but don’t want to spend much money on it.

The Corsair SF600 is one of the best PSUs for GTX 1090, and there are various reasons behind this claim. Many PC users have claimed that this PSU had its pros and cons, but the pros were always going to win each time.

First, I will be talking about the visual appearance of this PSU. It is not special; it is all black with that Corsair SF600 logo printed in silverfish-white color and nothing more peculiar.

Now, let’s talk about the installation part. Guys, the installation part for me at least was a hassle because I was installing this one in a huge pc case. Now you guys might be wondering how this could be a problem. So basically, the power cable that came with this one is like a foot in half, and the rest you can understand.

I always advise measuring your PC components, but I wasn’t aware that the power cable would run this short for me. Even in my mid-sized tower, the power cable was insufficient. I am disappointed that a modular design would have this much petty flaw. But then, thankfully, my compact PC case came to the rescue.

Besides the length, the quality of the power cables and every cable that came along with this PSU was superb. Every cable was sleeved with high-quality material, which I guess is the specialty of Corsair.

I tried running it under load, and the performance was decent. Also, I liked how there was no noise even when the PSU was under extreme load. But guys, it ran a tad hot when it was under heavy load. Which I didn’t like, actually.

I would recommend the SF600 to anyone looking to use 1080 for their usual content creation or sometimes for a gaming session. I would not recommend this PSU for serious PC users, especially overclockers, as it can sometimes fry up.

REASONS TO BUY

Completely silent

Fully modular design

Compact design

Superb power efficiency

REASONS TO AVOID

Short power cables

Runs hot under extreme load

WHY YOU SHOULD CHOOSE THIS PSU?

The Corsair SF Series SF600 is one of the best fully modular PSUs for GTX 1080. The cable that comes with this PSU might be a bit short if you have a wide pc case just like mine. Besides that, it is not recommended for extreme gaming because it can then fry up.

Budget Pick

Corsair CX450M

Best PSU For GTX 1080 Budget Pick

SPECIFICATIONS

Brand:Corsair | Wattage:450W | Design:Semi Modular

You might be wondering where the budget pick for today’s best PSU for GTX 1080 is as we are approaching the end of our list. Don’t worry, guys, because I had thoroughly tested and tried every budget PSU possible to give you one of the best and most reliable picks.

I made sure that our budget pick belonged to Corsair because it is one of the most trusted brands for supplies. The Corsair CX450M is one of the best budget power supplies for the GTX 1080 for many reasons. It also has some cons, and keep on reading this article to know all about this PSU.

The fact that it is semi-modular is what I liked the most about it. This greatly improved cable management. I no longer had the “rat’s nest” of cables in the bottom of the casing because I no longer required the PCI-e or 4-pin connectors. Moreover, another amazing thing is that the cables are also of the ideal length.

This power supply wasn’t silent. Even though the system was turned off, I could hear it 25 feet down my hallway. It’s not a bad power supply; it does the job, but unless you enjoy the constant noise of a noisy power supply, don’t install it near any living space.

I don’t know if I’d use something with this low wattage for a gaming PC because I like to go all out, but it’s absolutely perfect for a PC that will never see any gaming or heavy lifting.

REASONS TO BUY

Semi modular at this price

Fits into every PC case

Durable design

High quality performance

REASONS TO AVOID

Not completely modular

Not for gaming

WHY YOU SHOULD CHOOSE THIS PSU?

Corsair CX Series 450 is a budget pick PSU among our 8 best PSUs. It delivers high-quality performance and is affordable at the same time. Even though it is not semi-modular, one can expect that at this price. Also, if you are a heavy gamer, the voltage would be totally insufficient.

Thermaltake Toughpower PF1 650W

Best Quiet PSU For GTX 1080

SPECIFICATIONS

Brand:Thermaltake | Wattage:650W | Design:Non Modular

Got just $90 in your pocket? Then get a Thermaltake Toughpower PF1 because it is one of the best PSUs for GTX 1080 under $90. You can pay up for this amazing PSU and then have some money aside for another PC component; all that is $90.

I tested several power supplies ranging in price from $80-$200, and guess what? This is the Toughpower PF1 that I looked after. The determining issue for me was AC ripple and noise, and it delivered the greatest results out of the 10 units tested, indicating that their marketing isn’t like to Be Quiet!

It was simple to install in an ATX mid case, and the wires were long enough to reach everything I required, even with my unconventional cable management. It also had a power switch on the back, which was convenient.

Molex connectors are included just for more mess to contend with. Also, I dislike the daisy chain since it makes a mess every time I see it. Finally, it is not modular. Although the advertisement claims otherwise, dealing with this one made me like semi-modular designs even more after dealing with Molex connectors. The power supply was very quiet and still worked perfectly after a year of use. If you take anything away from my evaluation, it is that it is a good PSU that has established itself.

REASONS TO BUY

Decent wattage

Very quiet

Variety of cables

Great build quality

REASONS TO AVOID

Non Modular

WHY YOU SHOULD CHOOSE THIS PSU?

The Thermaltake Toughpower PF1 has a decent wattage and comes with various cables. The design is non-modular, but if you are not a beginner, you will have no issue setting it up.

EVGA Supernova P2 650

Efficient Powerful Supply For GTX 1080 

SPECIFICATIONS

Brand:EVGA | Wattage:750W | Design:Full Modular

The EVGA SuperNOVA P2 650 is a good value PSU for 1080. It is a superb, well-designed choice that can handle even the most demanding gaming machines. I don’t believe in overspending on computer components, but when it comes to power supply, I believe you get what you pay for.

And because the EVGA Supernova is the finest premium PSU for the 3080 for this reason, I would recommend purchasing it if you have any spare cash. Let’s start with the overall appearance. The PSU has a black matt appearance that I initially found appealing.

Furthermore, I believe the build is sturdy and will last a long time for me. The second feature I appreciated was the length of the cords. Because this power supply is totally modular, the provided wires are ridiculously long.

And, as far as I can tell, they can last as long as your PC case. However, some users may not have enough space to accommodate such long wires, which may be a disadvantage.

One thing is that the manufacturers could have made the power source wire and cord a little longer and of higher quality.

Why should I pay an extra $100 on this when I can get the same performance from the Corsair RM750x? As if I needed an excuse to spend an extra $100 on this power supply.

REASONS TO BUY

Beautiful aesthetics

Quality built fan

Factors To Consider Before Purchasing The Best PSU For GTX 1080

Here are some of the things to consider while purchasing the best PSU for GTX 1080.

Wattage

For this have a check of your components first. For the stance you don’t want to go for a PSU that has a limit of 400W whereas your system needs a 600W. This will damage the components of your system and will not give you that efficient performance.

In most cases the GTX 1080 will need wattage of 600 minimum. If you ever go above this rate you might have to pay extra bucks in the electricity bills. But usually a range of 600-800 Watts is more than enough to power a GTX 1080.

Design

You can have a modular, Semi-modular, or non-modular designs in a PSU. It is always better to have a modular or Semi-modular PSU. The reason behind this is you get to connect the ports you want while arranging a neat and clean organized setup. However you can also go for a non-modular one if you know how to connect ports.

Cooling System

A PSU is nothing without a good cooling system. While purchasing a PSU remember to look for an efficient cooling system. Because GTX 1080 consumes a lot of energy therefore it also generates a good amount of heat. For this purpose it is important to go for an efficient cooling setup.

Efficiency And Energy Saving

With a GTX 1080 try to aim for a PSU that has a rating of at least 80+. Remember the higher your PSU’s efficiency is the better it will perform. Also make sure the PSU you are going to purchase has enough power to turn on your system. You need to lookout for PSUs with energy saving operations. Of course everyone loves to save some money somehow.
