I bought it a few months ago, but the thread I linked in one of my earlier posts may give some insight into the problem. From the other thread I linked (This thread)
, the fact that PCIE 2.0 slots deliver 150W could be the difference between why your setup has no problems, and mine does. My new X48 board will be here today and I'll know for sure after I have it installed and running. My plan is to remove the "temporary) 2 x 6 pin to 8 pin adapter when I install the new motherboard.
