The SLi certified power supplies can guranatee to work with your specs. 550 watts deliver a lot of power and should be adequate. I would get an Antec 550watt SLi power supply.

Absolutely. No less than 550watts if you want to use two video cards in SLi configuration.

sli demands a lot of power. 2 high end video cards like the 7900gt's will definitely need a lot of power. the minimum is 550... any less than that probly won't power them, or you won't be able to get the most out of those cards
