Warning! To avoid damaging the
power supply or the motherboard,
please use a power supply that con-
tains a 24-pin and two 8-pin power
connectors. Be sure to connect these
connectors to the 24-pin (JPW1) and
the two 8-pin (JPW2, JPW3) power
connectors on the motherboard. Fail-
ure to do so will void the manufac-
turer warranty on your power supply
and motherboard.
3-6 Connecting Cables
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.
