For my system I use the semi Modular Antec true power 650w, so I would say that or it's 750w brother.
And they are good value for money.

I'm betting a quality 550-600w unit would suffice just fine. Another vote for the TPN 650 though .

I'm going to load mine down with 470 SLI and a 1055T here soon .

No it couldn't. If I remember the review correctly, that Mushkin is more like a 450-500w at best unit, and I want to say it was pretty mediocre.

Spec wise it sez it has a 4 12v rails with 20A each with 485W, I rly cant see how it would be able to run only 1 6870 with the numbers your suggesting.

P.s(Though I did buy it in 2008, so I will change it anyway hehe)

6870 is a 150w GPU. That 580 unit can pull 38a/456w on 12v. Based on what you have, CF rig needs sowewhere around 530w. You need a solid 650w unit for some headroom. For a typical modular 650w unit, something likes Antec tp-650 is fine.

You just answered your own question .

485 divided by 12 = 40 amps.

Keep in mind, that is PEAK power, not continous. Like I said, its more like a mediocre 450w unit.

The Antec TPN 650 has 650w CONTINUOUS on the 12v rail.
