700watt ULTRA XVS can run 2x8800gt?

[jinho11104]

right now my budget is 100$ so i can get myself a used 8800gt here..

the problem is. will my psu run them good?

i dont see ANY reviews on this psu and last time i tried... i got stutters in games(CSS)

it will be swell if someone with the same PSU tell me


i dont want to buy the second card and find out it was the PSU that was the problem all along..

because i am thinking maybe it was my m2n sli 570 mobo.

For a single card you should be fine but the PSU is still questionable. Not sure of the quality or if it matches up with the output of similar 700W units.

Ultra isn't known for the best of PSUs although I don't know the OEM who makes their 750 model. The corsair 750tx can be had for 100 and is certainly better quality (and customer service)

Ultra XVS I believe is a Wintech OEM build...meaning they are not very good. I also think it is an older ATX design. Only 40A on the 12V rail, which should be enough for 8800GT, but is pretty pathetic for a 700W design.

If that is what you already have, may as well try it.

so it wouldnt run good with 2 8800gt?

what about the zalman 600watt? or the corsair 550watt

I'd go with the OCZ GameXstreme 600w PS. It has 72 amps over 4 18 amp rails. I'm running 2 8800GTs in SLI no problemo.

For dual 8800GT the Corsair VX550 is good enough, but the TX650 would be better, or heck the TX750 can be had for $100 after rebate. I personally wouldn't feel comfortable running SLi on an OCZ Game, Stealth or ModXstream considering the ripple issues. PC P&C 610 Watt would be good. Coolermaster Real Power Pro 750W.

No it doesn't. 72A on 12V would 864W of 12V alone. You cannot simply add the rails together to determine the combined output. Unfortunately OCZ/FSP do not add them up for you and give you a value, but considering the 12V, 3.3V and 5V rails combined are limited to 580W, the PSU is capable of no more than 48A on the 12V rail, and more likely something along the lines of 40A-42A
