An apparatus and a method for supporting multi-processors and a motherboard using the same are provided. The apparatus receives the pins Z36 and AK36 of the Socket-370 central processing unit to determine which type the Socket-370 central processing unit is. According to the suspend status input signal transmitted from the south bridge of the motherboard, the determined result is latched, and some appropriate circuits are coupled to the Socket-370 central processing unit via a switch circuit. Meanwhile, the suspend status input signal is delayed and used to cut off the connection between the Socket-370 central processing unit and the apparatus. The delayed suspend status input signal is further delayed and then sent to an ATX power supply to activate the whole system.
