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 specifi cation and must
be connected to your power supply to
provide adequate power to the system.
See the tables below for pin defi nitions.
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.
