Power Supply Connectors and Voltages Refer to the following figures when checking for voltages on power supply cable connectors. When checking voltages, the power supply fan must be running. To power-on the power supply without using the on/off switch, use a screwdriver or other tool to short the connector JP3 (with the switch cable disconnected from the connector on the syste board), or use a connection (jumper) to short the black and green wires of the 20-pin connector on power supply. 20-pin Power Connector Pin-hole side view Cable side view Power Supply Output Pin Assignment Pin 1 2 3 4 5 6 7 8 9 10 11 12 13 Voltage +3.3Vdc +3.3Vdc Ground Power-on Ground +5Vdc Ground Power Good +5Vdc +12Vdc +3.3Vdc -12Vdc Ground Cable Color Orange Orange Black Red Black Red Black Gray Purple Yellow Orange Blue Black Parts/Test Point Locations 111
