My motherboard failed a couple days ago and I decided it's time for a new computer.

I've been reading about all the new PSU's out there and want to make sure my new system will have enough juice. My old PSU is the Seasonic SS 400 w. A very great PSU, but it lacks some connections I need.

I've already bought most of the new stuff I need, but I couldn't find any accurate wattage ratings for my gear. I'd like to stay with Seasonic, so I'm considering the S-12 430, 500 & 600.

I'll be running the AMD X2 3800+ (how much wattage do dual core CPU's use, twice as a regular CPU?), a Jetway GT4 SLI mobo. 2 sticks of OCZ 1g. Two evga 7800 GT's in SLI mode. A couple of optical drives & an older IDE Western Digital 120g HD. Plus a few 12 cm case fans @ 7 volts.

I know those 7800 GT's are going to be wattage hogs and the 500 & 600 come with some SLI features. Will 500 be enough?

Thanks guys.

S12-430 would suit your computer very well have have juice to spare. Antec Phantoms are also very good.

You're sure a 430 watter will provide enough juice for two 7800's? What's the wattage on those things - are they hotter or perhaps about the same as a 6800 Ultra? And what about a dual core CPU? I think I'd like a 430 more because I want to be as close to what I need as possible so I can be as efficient as possible. The nice things about the 500 & 600 is that it comes SLI ready. The 600 is even SLI certified. What to do... what to do...
