You also checked the power connector on the motherboard, and found that the 12 volt pin is only showing 6 volts. What is the most likely cause of this issue?

A) The power supply is faulty

B) The motherboard is faulty

C) The computer devices that use 12 volt power are faulty

D) The wall outlet voltage is mismatched to the power supply

E) Did I forget to pay the power bill?
