   |  Do you think a 550W PSU can handle SLI 8800's? I have the Mushkin 550...and out of curiosity, does anyone know either A) if it can handle two 8800's or B) how to figure the exact power usage for each graphics card? (And as far as what else it's running / the exact specs, they're all listed here.) Danke.

|  Re: Do you think a 550W PSU can handle SLI 8800's? I'd say no, not enough amps for two The 8800's need 26 amps minimum on each 12 volt rail. The PSU listed only has 20A each 12 volt rail. Then there are the other system drives.

| Re: Do you think a 550W PSU can handle SLI 8800's? I'd say a better choice is the Seasonic 550W. It has, I think 70 amps.

| Re: Do you think a 550W PSU can handle SLI 8800's? That's not how amps really work. Adding up all the amps on the 12v rails really don't give you a good idea of your power. Also, your PSU uses Rail Fusion technology, which means you won't be able to put more than a 28amp load on the rails combined, and up to a 14amp load on each. To be honest, it could possibly work, but I'm sort of doubting it.

 | Re: Do you think a 550W PSU can handle SLI 8800's? There is no doubt. It will work!! Now, if you do uber overclocks on the CPU and Both GPU's, Well you "may" be pushing it... But we shall see. And Dammit I was susposed to get a kilowatt metter with my room cooler today!!!!!!!! BAH BAH, if I did I could easily tell you how many watts my comp eats when on max load....
