Power Connectors

A 24-pin main power supply connector(JPW1)
and two 8-pin CPU PWR connectors
(JPW2/3) are located on the motherboard.
These power connectors meet the SSI EPS
12V specification. These power connectors
must also be connected to your power
supply. See the table on the right for pin
definitions.
Warning: To provide adequate power supply to
the motherboard, be sure to connect the 24-pin
ATX PWR (JPW1) and two 8-pin PWR connec-
tors (JPW2, JPW3) to the power supply. Failure
to do so will void the manufacturer warranty on
your power supply and motherboard.
