I recently upgraded my system and am waiting for the parts to arrive in the mail this week. My rig will be as follows:
Case: Antec 902
Mobo: Asus M4N98TD AM3 980a SLI
RAM: G.Skill ripjaws 4GB DDR3 1333 Cas 7
CPU: AMD Phenom II x4 955 Black
HDD: Western digital 750GB Caviar Black 32mb
OD: Samsung DVD burner
PSU: Corsair 620hx 620w
GPU: EVGA GTX 460 1gb.
I know my PSU will run this system just fine.
My question is down the road a year or so I plan to add a 2nd 460. Does my PSU have the power to run a second 460 with those other components? The only other thing I might add is a BD-ROM drive. But I can forgo that to add the second card.
Drop your Rigs specs in here and see what it recommends man, http://www.thermaltake.outervision.com/
Try it with one and two gfx cards to see the difference
could also check out the Bluray while your there
