Here is the Corsair:

See how under the three 12V rails (18A each), it stated 480W. That's the total load across the 12V rail. Since 480/12 = 40, that's 40A

Also, you often know immediately that a PSU cannot deliver the full sum of the 12V rails. Again, the Corsair: 3 x 18 = 54A. 54 x 12 = 648W. Howevr, the PSU itself is only 520W
Oh yeah...isn't that a phyics equation? It's totally out of my head (lol)

voltage * current = power

V * A = w

I recently picked up this Enermax 500w for my dad's 8800GTS and FX-62 build. Haven't had much of a chance to play around with it yet, so can't say if it's sufficient or not (8800 hasn't come in the mail yet ).

The corsair will be just fine running a rig with a single 8800GTS and a Quad Core CPU. That thing delivers 40A on the 12V rails. The Thermaltake Toughpower is an ok PSU (TT isn't as bad as they used to be. They put out some decent PSUs lately!). It probably doesn't deliver a whole lot more on the 12V rails than the Corsair does (can't find the specs, but my guess is around 45A).

For $10 more than the Thermaltake you can get this Silverstone:
http://www.newegg.com/Product/Produc...82E16817256021

Fully modular, 650W, single 12V rail of 54A, rated at 50C(!).

I'd either get the Corsair, or go for the Silverstone.

To Yraen: The Enermax will be good enough for your dad's rig. 32A is enough. However, I don't think it'll be able an overclocked Q6600 in the equation though

The Seasonic's are meant to be quite good for power efficiency, notably the M12 model with modular cables.

Yep, near 85% if I remember right. Then again, those are Seasonic's own ratings...

will the silverstone DA650 psu fit in my antec p180 case? or will i have to modify it some. i have read that this psu is significantly larger than the OP650 psu.
