Connecting Cables

ATX Power Connector

There are a 20-pin main power
supply connector(JPW1) and two
8-pin CPU PWR connectors (JPW2/
JPW3) on the motherboard. These
power connectors meet the SSI EPS
12V specifi cation. For the 8-pin PWR
(JPW2/JPW3), 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 JPW2/JPW3 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 motherboard, please
use a power supply that contains a 24-pin and two 8-pin power connec-
tors. 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.
