Tommy thought id answer in here as you sent me this way
according to AMD
Quote:
500 Watt or greater power supply with two 75W 6-pin PCI Express® power connectors recommended (600 Watt and four 6-pin connectors for AMD CrossFireX™ technology in dual mode)
soo i was wrong in my earlier comment, but youd need to run the second card on a separate rail so if you only have one rail with the 4/6 pin ends you'd have to spur from another rail with an adapter.

**edit** yeah i was wrongggggg

I figured as much 52 amps is enough correct if i get an adapter ?

yeah should be, as long as you dont have a psu with selective rails. what i mean by that is some PSU's limit the amount of watts a rail can pull, say like 150w, thats fine for a couple of hard drives, but obviously not for a gpu. soo make sure your PSU can draw ***w from a single molex or serial rail. shouldnt be an issue with a modern PSU, then again most PSU's have crossfire in mind.

if that doesnt make sense i apologies its 1am and im sleepy

it's cool i can call the techs at the store to double check which probaly won't help but won't hurt to ask

It would be a cheaper route and i could get it rolling tonight which would be cool

Ok the guy at frys was saying i would need about a 850w because im running a OC 4.0 ghz 5 -120 mm fans two 80 mm fans on the heatsink

Do you think this is true ?

But he said it would run on this PSU fine untill i told him my system specs

Another possible option would be to add a second power supply if possible....
