hey guys... i've heard that the 24-pin PSU's are required for the SLI boards...
and i know that antec, ultra X-connect are good..
where can i find one at about 500W...maybe more????

newegg, try the enermax, here is a link to newegg

What is your price range?

Silverstone is a good choice.

price range? well whatever i can find i like i guess...lol
dont really have one

The silverstone one looks good.

antec neopower was my choice, it comes with a 24-pin mobo connector, i didn't actually want a 24-pin... rather than use the ugly adapter i'm gonna rewire it to 20-pin...

dual 12v rails, 3% tolerances (most psu's have 5% tolerance or higher), modular connectors and clip-on extra connectors...
