I'm trying to figure out which Power supply would be better for the Asus A8N-SLI premium board I?m going to buy, either the SeaSonicS12-600, or the PC Power & Cooling 510. I'd rather go with the Seasonic (cheaper) if the Amperage on the dual 12v rails are suitable. I plan on getting a geforce 7800gt and my cpu will be an Athlon 3700+ eventually ill max out the ram (4gigs DDR) and have 2 to 3 hard drives in the system. I might replace the processor With an Athlon-FX or X2. Any suggestions?
