630W enough for SLI?

GgEnvy · 8 Aug 2010 at 14:05

I was wondering if my 620W Corsair HX620W PSU is enough for SLI/Xfire?

Msi H55-GD65
Core i5 750 (3.8ghz OC)
Asus EAH5770 CuCore
4GB Ddr3 Samsung unbranded ram
Corsair H50 watercooling
x1 Viper high rpm fan
x2 200mm Coolermaster fans (1 LED)
x2 100mm fans (2 LED)
x1 140MM fan (1 LED)
Coolermaster HAF case
1DVD drive
Soundblaster X-fi Xtreme audio.

Would this setup allow me to add another EAH5770 card?

If you had a cheap and nasty psu then i would have doubted it. Seeing as you have a corsair and the 5770 isn't a power hungry card, i think it's safe to say you'd be ok.

You can xfire 5870's on a 650w psu so i think you're safe.

Yep more than good enough

The psu will be fine for your setup

I would run two 5770s on an overclocked rig with a Corsair 500W and would not worry about it!

Thanks for the replies guys, I had no idea how to work out all the power usages

More than enough
