Hey guys, my recently custom built Q6600 rig is complete but I failed to boot it up today.

Upon connecting it to the power supply i get no light on the mobo when the ATX cord is connected to the mobo.

Power supply is a Cooler Master 460W, and mobo is a P5KC.

Which one is more likely to be at fault? Both are new.

Is there anyway to test with a tester kit etc?
