Both Corsair and EVGA are great brands that both make GREAT power supplies. You can’t just compare the two brands and ask “which brand should I choose for my next PSU?”.

The quality of a PSU is determined by a specific model, not the brand.

Even if one brand is better than the other, the differences would be very small and insignificant. It’s actually unnoticeable.

I’m glad to say I’ve used both EVGA and Corsair power supply in the past, and never experienced any failure. They were all great overall!

When choosing a power supply, look for a reliable model and enough wattage to power your system.

Also, look for PSUs that have a long warranty. A power supply with a 10 years guaranty is usually a sing that it has a great build quality.

Efficiency

Both EVGA and Corsair offer PSUs from Bronze to Platinum efficiency. If you’ve got a limited budget, you should consider the power efficiency of the power supply. It can save you a few bucks per month.

Finally, there’s the noise. Some power supplies have a silent operation mode, making it silent for low power operations

Cheap PSUs are usually the noisiest ones.

The build quality is determined by the specific model, NOT the brand.

Having that said, a 150$ power supply will be just as reliable as a 500$ one. The difference in price is only determined by the power efficiency.

For a mid-range build, choose a 150$ power supply from a reliable brand (like Corsair and EVGA) and you won’t have to worry about the build quality.

Please, don’t get those expensive power supplies just because of their flashy RGB lights features. It’s an absolute waste of money.

Most high-end cases have a special basement to hide the PSU anyway.

If you’re willing to spend the money, choose a power supply with a lot of headroom for power (750W+). That would be plenty more than you would need with a single mid-range GPU build.

Your best value PSU would be the Corsair RM 750x. It’s the most powerful you can get for the money. Unless you plan on having dual video card, it provides more than enough power than you will ever need.

Advantage of choosing a EVGA power supply

Personally, I love EVGA products for their extended guaranty. They usually have a 10 years guaranty, which is great. A guaranty that long also proves that they make great quality products.

Does higher price = better?

Actually, yes. Cheap power supplies tend to overheat and fail prematurely. They are also dangerous and can catch fire due to overheating. Stay away from cheap PSUs.

On the other hand, reliable brands like EVGA and Corsair PSU are extremely well built. They’re made from high-quality Japanese components that conduct the electricity extremely well.

Of course, the actual electricity efficiency depends on the model. Those with better efficiency come at higher price. If you care about electricity consumption, go with a 80+ titanium or Gold.

Quick pick: the EVGA SuperNova G3 for its value/money. It is very well built. It provides 550W of power, which entirely acceptable.

Considering new components become more and more power efficient with each generation. Like AMD’s new Zen 3 CPU lineup for example.

How much wattage should my new PSU have?

The wattage of your power supply should be around 650W. That is plenty for most gaming and productivity PC builds.

There are power supplies that go up to 2200W that cost $400+. Unless you plan on having multiple video cards and multiple CPUs, with tons of hard drives, having this much Wattage is totally overkill and is a waste of money.

Good rule of thumb is to choose a power supply that provides between 25% to 40% above your system’s power requirements.

Is the power efficiency of a PSU really important?

Have you ever noticed your smartphone being hot, or very warm? That is energy that is basically “wasted” or “lost”.

It’s the same thing for power supplies. Some PSUs have great efficiency, at around 94% power efficient. Others have lower efficiency, at around 85%.

Power supplies follow a precious metal rating (Bronze, Silver, Gold and Platinum). Bronze being the less efficient, at 85% and Platinum being the most efficient, at 94% efficiency.

  • 80+ White: 80% power efficient
  • 80+ Bronze: 85% power efficient
  • 80+ Silver: 88% power efficient
  • 80% Gold: 90% power efficient
  • 80+ Platinum: 92% power efficient
  • 80% Titanium: 94% power efficient

Now, is this important at all? Should you consider the power efficiency when buying a new power supply?

In my opinion, it really doesn’t matter. The only difference it will make is save you a few dollars per month.

Now yeah, Platinum PSUs can save you around 30$/year in electricity cost. But those cost around $80 more than Gold or Silver rated ones. It’s really not worth it in my opinion.

Get a Gold rated power supply that’s slightly less efficient, and save yourself $80.

I love these two companies for their power supplies, but any PSUs with above Gold efficiency is just a gimmick.

Corsair’s best power supply: Corsair RM750x

SeriesRMx
BrandCorsair
Wattage750 Watts
DesignFull Modular
Dimensions LxWxH6.3 x 5.91 x 3.39 inches
Weight3.65 Pounds

Corsair’s RM750x is definitely on top of my list. It has an 80+ Gold power efficiency rating, and 750W of power. Making it perfect for overclocking your CPU. Unless you plan on having a dual graphic card setup, it’s more than enough power for any high-end gaming PC.

Its 120mm fan keeps the PSU relatively cool, while being very silent. That’s right! You won’t have to worry about the noise of your system sounding like it’s goanna take off right next to you.

And lastly, it’s a modular PSU! That means you can plug only what you’re using and unplug unnecessary wires laying around. It’s great for airflow and make your case more organized.

EVGA’s best power supply: EVGA SuperNova 650 GM

SeriesGM
BrandEVGA
Wattage650 Watts
DesignFully modular
Weight2 pounds
Dimensions LxWxH10.55 x 3.82 x 7.68 inches

I absolutely love the SuperNova 650 GM. It’s compact, making it perfect for smaller computer cases. It’s equipped with a small 93mm fan which is very efficient at cooling.

It’s also modular, so you can unplug unnecessary wires laying around. Helping keep the inside of the case organized.

The only downsides are that it makes slightly more noise than some other PSUs. Also, because of its smaller size, it’s not the most efficient at cooling. Don’t worry though, it shouldn’t cause any huge problems since it’s one of the best rated PSUs on the market.

This was my comparison between Evga and Corsair power supplies. Thank you for reading!
