I just recently got myself an EVGA GeForce GTS450, which only requires a 400 Watt power supply, I have a 500W Rosewill, but the card says it requires a minimum of 22amps on the +12V Rail.
I looked on the side of my Power Supply and it can only go to about 20 Amps.
I'm looking for a 600-700W power supply for my computer that'll definitely have 22amps running on it's +12V rails.
Anyone have a suggestion for a good cheap one?
Thanks for any replies!

Yes. Newegg had a corsair builder's series 400w with 28 amps for $18 after rebate a few days ago.

Well, thanks for that and all (Seriously, that sounds nice) but, the card requires a 400, so, I'd like all the rest of my stuff to run WITH the card, lol.

What matters is the Amperage on the 12v rail. The two major things that use power from the 12v line is the GPU and your CPU. Everyting else, case fans, hdds, etc is literally nothing.

As long as its a quality make with good internal parts and a strong 12v rail, it'll support your build.

Its not the watts that matter, its the amps on the 12v and quality that matters.

Thanks, man!
I think I'll go for the CX430w
Oh and, you said the fans, hdds, ect are litterally nothing, like, as an example, how much would you GUESS a high-end HDD would take up?
