ATX Power Connector

There are a 24-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 at JPW2 is
required to provide adequate power to
the PEI-Express slots. See the tables
on the right for pin defi nitions. For the
8-pin PWR (JPW3), please refer to the
item listed below.

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 motherboard.
