5970, I7920 OC, PSU requirements

Hey there, I'm building a system with an XFX 5970 and an I7 920 @4ghz, 12gb ddr3. Do you guys think an 850w PSU would suffice? needless to say I would be looking to overclock the card.

A HD 5970 proximately consumes 450 Watts knowing that you o/c your I7 920 + 12 GB DDR3. I advise you SeaSonic X750 Gold.

It's just the card who consumes 450 watts. if you add CPU with the GPU in load you'll proximately reach 550 watts or 600 watts given that you'll o/c the CPU + GPU. SeaSonic X750 Gold 750 watts will suffices in addition she has gold medals label (90% efficiency)

yeah, also how many disk drives are you running off this thing?

if you want lots, or even quad fire, grab a corsair HX 1000 w and that will last ya through multiple builds

if you want to quadfire, 1000w and above is needed, esp with 5970s.

I would suggest that since you are buying high end parts now, go with a HX 1000 or a toughpower 1200w or something like that, as you will want room to grow and I hope you are getting something like a HAF 932 or antec 1200 to house all of this.

in this current setup, the 850w is more than enough, and should even allow for a few more hdds and what nots

yap well if you have one already then use it first, and when you quadfire simply grab a better one then, psu prices don't really fluctuate like gpu or cpu prices on the good brands (save xmas and what nots) and so there isn't a rush for it


the cosmos s sport is seems to be a fine case and should do you well, although i still favorite the HAF 932 my self since it has 3x 230 mm fans for maximum airflow, but the cosmos do look sleeker and with it's 150 cfm side fan it can't be that much worse off for gfx cooling than the 932
