I Just have a question, will a Seasonic SS-400ET with two 12v rails @ 17A handle my 4890 + Athlon II X3 and 1 HDD? www.seasonicusa.com I'm planning to overclock the 4890 and my CPU a bit. I'm expecting someone to recommend a 500W OC/Corsair PSU, but is there any hope?
Also, are two 12v rails @ 17A better than one 12v rail @ 30A?
Spending a little extra on a PSU purchase towards a better quality product is always a wise decision.. Having said that, i would recommend an Antec EA-650.. Its efficient, priced right and also modular which helps with cable management..
