Which PSU is better?

XFACTORMAN · Aug 1, 2014

I am building new gaming PC and I need some help with it. Which power supply is better for this build :
1. EVGA SuperNOVA NEX 650 G 80 PLUS GOLD or
2.XFX Pro Series Modular Edition (Bronze) 650W
or do you have any other, better suggestions for this particular build?
Thank you for your help.

XFX for sure!

top PSU manufacturers

Corsair
Antec
XFX
Seasonic

EVGA is not bad but they had some reliability problems.

Yeah but this EVGA PSU is 80+ Gold vs XFX 80+ Bronze and EVGA is fully modular. You think XFX is still better?

XFACTORMAN :

Bronze is fine. The extra money for gold is a waste.

It's not that the extra money is a waste, exactly, because the power supply is more efficient, you will save a bit on power. However, I do question whether the difference in the price of power would actually make up the difference in the price of the power supplies over the normal life span of a computer power supply.

? The gold one is cheaper. By a lot. I'm not up on all of evga's PSUs, but it should be fine.

Armo1000 :

Antec, XFX and Corsair are not manufactures of PSUs. In fact most of there PSUs are just rebranded Seasonic. With that being said, between the four, it really just boils down to the little bells and whistles and price. Quieter fan, nonmudular or modular, amps on 12v rail, etc. etc.

I would go with the xfx over evga because they are more reliable.

Only the EVGA , B2 , G2 , PT , AND T2 , are the good models , they are made by Super Flower.

The one you listed isn't one of the good ones.

The XFX model in this case is the better PSU.

It's not that bad. It's a FSP "Aurum". Which I assumed as much when I saw the price and the gold efficiency. HardOCP gave it a passing grade. Not flashy, but not junk either.

the unit did pass the Torture Test and the voltage regulation changes are calculated in above. When we look to the efficiency, we see that the unit posted efficiency values which ranged from 87.21% to 90.40% at 120v

They also reviewed the XFX unit.

The efficiency ranged from 79.09% to 87.18% at 120v

In addition to being more expensive, the XFX unit tops out at where the EVGA unit starts in efficiency. The XFX unit is a good one, but I'm not sure why I'd buy it over the EVGA/FSP unit. According to newegg it even comes with a 10yr warranty. I know it's not a flashy unit, but the EVGA is still one I would run. (I almost bought the 450W or 500W Aurum, but passed when I saw it didn't have an MOV. I now know it's not the end of the world.)

FSP Group is fine as far as an OEM is concerned. Not as good as SeaSonic, but not junk by any stretch. That particular EVGA has a ten year warranty upon registration and EVGA has very good customer service regarding RMAs. The XFX is better quality, but the EVGA is a lot better deal in my opinion.

XFACTORMAN :

When comparing just effeciency, the difference between ratings of gold, bronze and even platnium are really insignificant when your only running a home computer. As long as it at least 80+ standard certified your good.( you can verify that here: www.plugloadsolutions.com/80pluspowersupplies.aspx)
IMO I would go with this corsair 650 80+ Gold Modular for 119.00
If you can do 620 you can try Seasonic 620 80+ bronze modular for 89.99
