Compucase 1000 Watt This is one of my favorite PSU brands. They are really reliable at least in my experience. I have 585 Watt one powering my mom's computer i built for her.

EDIT: And an ASUS 23.6" HDMI & 1080P

HEC isn't too bad of a company, but if you are going big, then go big or go home. I don't like that they split that PSUs 12V into so many freakin' rails. If you are CFing 2 5970, look for something a little "beefier" as far as rails go.

Also, according to the PSU calculator on NewEgg, it'll take more than a 1000W PSU to power that. Then again, I'm no PSU genius so...

I think it'll be plenty. It's the amps that matter more than the Watts.

http://www.newegg.com/Product/Produc...-032-_-Product

anyone find me the specs on the rails for this PSU?

seems iv found it.

so... how do you know how many amps are on the rails to figure out if it can power a card?
http://www.jonnyguru.com/modules.php...Story&reid=177

says there are 6 12v rails.
each at 38Amps.
so do you add them up and get....228Amps?
or is it still JUST 38 amps?

i think i need like 70ish amps for dual 5970s

Since it's Antec, I guarantee it'll be enough to power your new system. I'm guessing they are around 18 amps per rail. x6 = 108 - 30 amps = 78 amps which is about the max of any power supply with one rail. And those things will run any high end system you need. Even a couple of super high end graphics cards and i7, 6GB of RAM, and 4 hard drives plus some extras. It'll be fine.
