You should have one powering the system and the other powering the cards, I don't see why it wouldn't be enough

Just check the +12V rail(s) for good amperage.

Could have been the +12V rails. If one's got like 3x18A rails, and only 1 of those rails is dedicated to the video cards, then it won't work.
