A 24-pin main power supply connector(JPW1)
and three 8-pin CPU PWR connectors
(JPW2/JPW3) on the motherboard. These
power connectors meet the SSI EPS 12V
specification. In addition to the 24-pin ATX
power connector, the 12V 8-pin CPU PWR
connectors at JPW2/JPW3 must also be
connected to your power supply. See the

Warning: To prevent damage to the power
supply or motherboard, please use a power

the three 8-pin (JPW2 and JPW3) power
connectors on the motherboard. Failure in
doing so will void the manufacturer warranty
