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.
