I am trying to build a gaming rig, and want to be sure that the PSU that I have in mind will be sufficient for the system i'm trying to build.
here are some of the parts i'm planning on buying:
RAM: 6GB DDR3 http://tinyurl.com/3xlzwyy
GPUs:2 x Asus ATI Radeon HD5770 1 GB DDR5 http://tinyurl.com/34nsdcp
CPU: Intel Core i7 Processor i7-920 2.66GHz 8MBhttp://tinyurl.com/3ys3pqm
Mobo: Asus P6TSE http://tinyurl.com/26qqr6f
HD: Samsung Spinpoint 1TB 7200RPM http://tinyurl.com/2f28bgm
And heres the PSU that I am looking at:
650W 20+4-pin Blue LED Fan ATX PSU http://tinyurl.com/2v6b7f4
I am pretty sure the wattage is enough, but shouldn't I need 2 +12V rails if I plan on using 2 cards in crossfire? I know the PSU i'm looking at is a little cheapo-depot, but i'm on a budget, and it would be GREAT if this thing can handle the setup I want!
