Power Connectors
A 24-pin main power supply connector(JPW1)
and one 8-pin CPU PWR connector (JPW2)
on the motherboard. These power connec-
tors meet the SSI EPS 12V specification.
In addition to the 24-pin ATX power con-
nector, the 12V 8-pin CPU PWR connector
at JPW2 must also be connected to your
power supply. See the table on the right for
pin definitions.
Warning
: To prevent damage to the power
supply or motherboard, please use a power
supply that contains a 24-pin and one 8-pin
power connectors. Be sure to connect these
connectors to the 24-pin (JPW1) and the
8-pin (JPW2) power connectors on the
motherboard. Failure in doing so will void the
manufacturer warranty on your power supply
and motherboard.
