Not just if the PSU supplies the GPU with enough Watts, but also, if there is going to be any problem connecting the 2 of the them.
I 've read something about "amps", "rails" etc., had never heard of them before, so if anyone knows, please take a look and let me know if there is going to be ANY problem at all if I buy this PSU for my system?
Yes it will work. The modular cables are really easy. You will prolly hook a 6 hole connect or maybe two in that card. I wouldnt go lower than a 750 though. Espescially, if you plan on adding anything else. Ive got the Thermaltake 850 modular that Best Buy sells. It has worked out good for me. I use both audio and video cards. Good Luck
