PSU Help

[SheepPunk]

Can anyone tell me how many watts this build need? And yes I've tried wattage calculators, they all give me totally different answers. Also, I don't know which PSU to get. So far I've heard great stuff about Seasonic. Can someone confirm that they're good?

500W if you don't plan on SLI

650W if you plan on dual SLI

850W if you plan on quad/tri SLI

Seasonic is a great brand/OEM maker of power supplies, they make many of Corsair, Antec, and the entire line of XFX Power supplies.

The Seasonic M12II-520 is sufficient for your build and slight-moderate OCs. Great deal on it right now at Newegg: http://www.newegg.com/Product/Product.aspx?Item=N82E16817151093&Tpk=m12ii-520
