Connecting Cables

Power Connectors

Two 20-pin power supply connectors and a 4-pin power connector are located on
the motherboard. The two 20-pin power connectors (J4/J6) are used as main power
supply to the system, while the 4-pin power connector (JP3) provides power to the
HDD panel for Chassis 808/809. These power connectors meet the SSI EPS 12V
specification and must be connected to your power supply to provide adequate
power to the system. See the tables below for pin definitions.
Warning! To avoid damaging the power supply or the motherboard, please connect
the power supply to a 20-pin power connector located at J4 or J6, and connect the
4-pin power connector (JP3) to the backplane or the HDD to provide adequate power
to your system. Failure to do so may void the manufacturer warranty on your power
supply and motherboard.
