XFX suggests 630W for non-SLI use and for SLI they recommend 680W or greater.

Good luck with your SLI project.

This is my PSU:


Could that thing handle two 8800GT's? That looks like 18 amps per 12 volt rail is that correct?

(Assume CPU is an intel E8400)

This has probably already been stated, but it isnt always the watt output as it is amps.

Oop-to the above. Im not great with power supplys, but if you have them on different rails it seems you should be just dandy.

I would not risk it. This isn't a very well designed PSU (it's actually a 500W design).

That isn't exactly a high quality PSU

Not only watts also pay attention to amps on your 12v rails.
post #40 of 43
Could someone school me as to what is a well designed or high quality PSU?

The amperage on mine looks sufficient, thatb 18 amps per 12v rail is it not?

That's more than enough for SLI right?
