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.
