View Full Version : Min PWR Supply Requirements for SLI

Currently i'm running an Enermax Noisetaker 470W 12v Power supply, will this be enough to run 2 7800 GT's in SLI?

depends on the specs?

Have a link, or list for the amps on each rail?

Yep i believe it should be enough ..

for my DFI board heres the recommendations :
3400+ , 6600GTx2 = 12v >17A , 350W
3800+ , 6800GTx2 = 12v >20A , 400W
FX-55 , 6800Ux2 = 12v >25A , 500W

your PC is about equivalent to the 6800GTs system.

Again, PSU problems are all overrated.
If you have a good brand PSU with enough 450+ watt you can do Probably most of SLI setups.

Poeple say you need BLAH BLAH BLAH BLAH.....!!

I think with your PSU " if it supports SLI " you can do 6600GT SLI/6800 series SLI and even 7800GT SLI.
Not sure about the 7800GTX though.

By the way do you overclock?

I prefer not when using SLI cause overclocking eat too much from your PSU.

Yeah it's down to brand but also good rails too. You could have a 680w PSU but 60% effcient or a 480w that is 90%.
