Power Connectors
A 20-pin main power supply connector(JPW1/
JPW3) and three 8-pin CPU PWR connec-
tors (JPW2/JPW4) on the motherboard. For
power on , either connector JPW1/JPW3, or
JPW2/JPW4, or both must be connected.
This board supports power supply redun-
dancy.
These power connectors meet the SSI EPS
12V specification. In addition to the 20-pin
ATX power connectors, the 12V 8-pin CPU
PWR connectors at JPW2 and JPW4 must
also be connected to your power supply. See
the table on the right for pin definitions.
Caution : To prevent damage to the power
supply or motherboard, please use a power
supply that contains a 20-pin and three 8-pin
power connectors. Be sure to connect these
connectors to the 20-pin (JPW1 and JPW3)
and the three 8-pin (JPW2 and JPW4) power
connectors on the motherboard. Failure in
doing so will void the manufacturer warranty
on your power supply and motherboard.
