Power Connectors

A 24-pin main power supply connector (JPW1)
and two 8-pin CPU PWR connectors (JPW2/
JPW3) are located on the motherboard. These
power connectors meet the SSI EPS 12V
specifi cation. In addition to the 24-pin ATX
power connector, the 12V 8-pin CPU PWR
connectors at JPW2/JPW3 must also be con-
nected to your power supply. See the table on
the right for pin defi nitions.
Warning! To avoid damaging the
power supply or motherboard, please
use a power supply that contains a
24-pin and two 8-pin power connec-
tors. Be sure to connect these con-
nectors to the 24-pin (JPW1) and the
two 8-pin (JPW2, JPW3) power con-
nectors on the motherboard. Failure
to do so will void the manufacturer
warranty on your power supply and
motherboard.
