It's totally random, if I disconnect the DVD drives all fans seem to power up fine, therefore, I assumed it was not getting enough power. Power and 4 in connectors are attached, I can't see to figure out the problem.
That psu should be powering it no sweat. Seems like you have a deffective psu. RMA it for another one or get a different psu.
The hiper 580w is a good psu in the same price range, but it won't supply as much power as the antec did on the +12v rails (you still would be able to run one 8800gtx if you wanted to with the hiper).
