ya.. no problem, i found out about it the hard way.. hahaha, but my compy still ain't running sadly, i just rma'd the mobo.. and from xtremeforums i think i saw 4. somethin ghz on water.. so they overclock very nicely
i grabbed a 680 watt just to be safe for crossfire 46 amp too.. you might wanna check that psu out, its only like 115 dollars.. and its got the same percentage of effeciency as the antec as well 70 %
