2-6 Connecting Cables
ATX Power Connector
The main power supply connector
(JPW1) on the PDSMA+/PDSMA-E+
meets the SSI (Superset ATX) speci-
fication. You can only use a 24-pin
power supply cable on the mother-
board. Make sure that the orientation
of the connector is correct. You must
also use the 8-pin (JPW2) processor
power connector for adequate power
supply to the system (*See below.)
See the table on the right for pin
definitions.
Processor Power Connector
In addition to the Primary ATX power
connector (above), the 12V 8-pin
Processor power connector at JPW2
must also be connected to your power
supply to provide adequate power
supply to the system.
