Cooler Master has chosen to use four +12V rails instead of delivering a single, large +12V output as many newer power supply manufacturers are electing to do.  This is accomplished by implementing current limiting circuits into the design.  The four +12V outputs are distributed as following.

    +12V1    (25A)    24-pin ATX, 4-pin ATX 12V, SATA, 4-pin Molex and 4-pin FDD
    +12V2    (20A)    4-pin ATX 12V (1/2 EPS12V 8-pin) x2
    +12V3    (22A)    (2) PCI-E 6-pin and (1) 8-pin
    +12V4    (22A)    (2) PCI-E 6-pin and (1) 8-pin
