[Hippoz]

Hi this is what I plan on buying for my new pc, what would a good psu to get for it, preferrebly something that is pretty efficient and fairly quiet (if possible).

Antec P180 case
Intel Core 2 Duo E6600 processor
EVGA Nforce 680I SLI motherboard
2 gigs of Corsair XMS2 ram
Seagate Barracuda 7200 320gb Hard drive
EVGA E-GEFORCE 8800 Gts (adding a second one sometime in the future)
samsung DVD writer

I also plan on overclocking it a bit, so any help would be appreciated.
Thanks.

Here is the list of SLI approved power supplies from Nvidia. Since you said you want to eventually go SLI, can't go wrong with one of the ones from there.
