This is the PSU I would buy right now if I needed to FSP Group 550W 4x+12v rail PSU
. PSU's with similar voltage and amps should serve you very nicely.
That is really expensive, and are quad 12v rails necessary?
my graphics card is a 6800gt (agp), but im going to buy a X1900XTX, or I will wait until a directx 10 card comes out, the upgrade will be around november or december, but still a single graphics card, i am not going to buy 2...
I also don't know much about SLi and crossfire, but my nvidia drivers tell me that the 6800gt has SLI support, would it be possible for me to hook this up with a pci express 6800 XT? and would it be as good as having a 7900GTX or X1900XTX?
