Most likely the motherboard has a shorted MOSFET on the CPU VRM (probably an upper MOSFET.) Either that or something wrong with one or more of the MOSFET driver(s).

Of course, before doing anything, first remove the CPU and check for bad pins in the CPU socket. If none, keep CPU off the motherboard and perform following test with multimeter (with PSU disconnected and unplugged from motherboard): put positive (+) multimeter probe on 4/8-pin CPU connector (12V rail) and put negative (-) multimeter probe on a ground screw. What resistance do you get?
