5.4 CN5: AT Power Connector
When using an AT compatible power supply, plug both of the power
supply connectors into CN5. Make sure the power supply connectors are
connected in the right orientation -- the black wires of each power cable are
ADJACENT to each other. That is, the black wires of each connector
should be aligned in the center of the CN5 connector.
