supply connector(JPW3) and two
8-pin CPU PWR connectors (JPW1/
JPW2) on the motherboard. These
power connectors meet the SSI EPS
12V specifi cation. For the 8-pin PWR
(JPW1/JPW2), please refer to the item
listed below.
Processor Power Connector
In addition to the Primary ATX power
connector, the 12V 8-pin CPU PWR
connectors at JPW1/JPW2 must also
be connected to your power supply.
See the table on the right for pin
defi nitions.

Warning: To prevent damage to your power supply or mother-
board, please use a power supply that contains a 24-pin and
two 8-pin power connectors. Be sure to connect these power
connectors to the 24-pin and the two 8-pin power connectors on
your motherboard for adequate power supply to your system.
Failure to do so will void the manufacturer warranty on your
power supply and motherboard.
