CM 600w and ATI 3870X2 crossfire

[coco16]

hello you think that a cooler master silent pro 600w can power quad gpu 2x 3870x2 in crossfire the max output of the power supply is 720w 40amps rail.

I just want to know I know it can power one of the card but idk about 2 of them.

They're rated at 223 watts each, so two of 'em will want 37 amps.
Not going to work on a 40a psu, sorry :(

yeah that was i imagine but i always like to ask but the psu will run one of them alone no crossfire
