2-5 Connecting Cables

ATX Power Connector

There are a 20-pin main power supply

connector(JPW1) and an 8-pin CPU

PWR connector (JPW3) on the moth-

erboard. These power connectors

meet the SSI EPS 12V specifi cation.

The 4-pin 12V PWR supply is required

to provide adequate power to the sys-

tem. The UIO PWR, located at J11, is

also required for the UIO slots. For the

8-pin PWR (JPW3), please refer to the

item listed below. See the table on the

right for pin defi nitions.

Processor Power Connector

In addition to the Primary ATX power

connector (above), the 12V 8-pin CPU

PWR connector at JPW3 must also

be connected to your power supply.

See the table on the right for pin

defi nitions.
