Windows 7 HP (64bit)
Intel Core i7-2600 Quad 3.4Ghz
8GB DDR3 1333Mhz RAM
Nvidia Geforce GTX 550TI

So my main problem is I want to upgrade my Video Card, Im currently running a GTX 550TI and want to upgrade to the 660.
When I had the computer built, I had the 600w PSU put in on purpose (Even tho HP said 460 was enough) becuase I wanted to be able to upgrade in the future. Judging by what Ive been able to find on the internet. The 660 requires 24 Amps on the +12V rail and a 450W PSU. Im not entirely sure how to find this out other than what is displayed on the side of my PSU


Do I have enough power to "power" my new 660? I dont want to damage anything and have been told that with the 75Ws from the PCI slot and the 1x6 Pin connector that I should be all right but Im just not sure. Amps confuse me to death, or at least, my psu does =p (Also wasnt sure where to post this )

Ive read on tomshardware that the 550ti required 24Amps, but at the same time none of those rails say 24 amps so im soo bumfuzzled lol
