This mobos take the CPU current from all PSU rails 3,3V, +5V and +12 V.
The power neded to overclock the CPU is more then 135 W. So the rails must give minimum 100 A ( I=P/U= 135/100=1,35V (The CPU voltage ), otherwise we have to increase the voltage to compensate the current neded by CPU . So a better PSU is this:

Interesting...could somebody buy this thing (only 499,99 $ ) and then tell us how it performs? Must be nice to have a 90 ampères 12V-rail, but 32 to 44 dB is a bit loud...
