It does. 44 Total Amps, Spread Across two Rails at 22 Amps Each.
If its 22 Amps PER CARD By themselves then youll want to look into one I linked or Look for one with four Rails @ 18 Amps Each.
Heres a good Review for the OCZ 700 Watt.
Btw the total Amperage is only 56.66 Amps and not 72 Amps.
Because 680 Watt Divide by 12 Volts == 56.66 Amps. Therefore each rail is capable of putting out 18 Amps but not all at the same time. Continious is only 14.165 Amps.
