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. See the table on the right for pin
defi nitions for connector (JPW1). 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 power supply.
See the table on the right for pin
defi nitions.
