When using an AT compatible power supply, plug both of the power
supply connectors into J3. Make sure the power supply connectors are
connected in the right orientation. The power supply connectors are
connected in the right orientation if the black wires of each power cable
are ADJACENT to each other. That is, black wires of each connector
should be aligned in the center of the J3 power supply connector.
