Power Supply for 3x 8800gts SLI

post #1 of 17
Thread Starter 
Just wondering what kind of power supply i should get with my new build.
EVGA 780i MOBO
3x EVGA 8800gts (G92)
Antec 900 case (so all those fans, not sure if they matter)

Should i get a 850w power supply? and what brand is good?

Thats not possible. Right now, only the 8800GTX and Ultra can do Tri-SLi. And the upcoming 9800GTX can also do tri-sli.

If you could somehow build that setup, you'd probably want to go with an above 1000w single rail PSU. I personally recommend Silverstone, but any good quality PSU maker should do fine.

get the GTX for tri-sli and a DA850 should be fine. try and get a single rail quality PSU from Antec, Corsair, Silverstone, or PC P&C
post #8 of 17
I doubt the DA850 could do TRI SLI GTX's

I'm gettting 2x 9800GX2's and it should be fine, but TRI SLI is a power hungry monster as the GPU's use G80 cores. Hotter as well.
