Connect the P1 and P4 connectors to the motherboard to supply power to the circuits.
The power supply provides electricity to the other components installed to the motherboard, as well as to the motherboard itself. The power supply connects to the motherboard through a P1 connector, a 20-pin cord supplying voltage lines through each individual cable that makes up the connector. Also found on the motherboard is the slot for the P4 12V (voltage) power supply connector. The P4 connector provides an additional 12 volts of power for Intel processors.
Instructions
1. Disconnect any cables attached to the I/O (Input/Output) panel located on the back of the case. Disconnect the power cord. Set the computer on its right side.
2. Loosen the screws securing the left cover to the computer. Pop off and slide away the computer's cover, and touch the chassis to ground yourself.
3. P1 Connector.
Locate the 20-pin P1 connector coming from the power supply. Insert the P1 connector into the 20-pin slot located on the motherboard.
4. Locate the 4-pin P4 connector coming from the power supply. The P4 connector looks similar to the P1 connector, except it has four pins, rather than 20.
5. Insert the P4 connector into the four-pin slot located on the motherboard.
