ATX Power Connector
The main power supply connector
(JPW1) on the X6DH8-XB/X6DHE-
XB meets the SSI (Superset ATX)
specification. You can only use a
24-pin power supply cable on the
motherboard. Make sure that the
orientation of the connector is correct.
You must also use the 4-pin (JPW2)
power connector for adequate power
supply to the system. 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 Pro-
cessor connector at JPW3 must also
be connected to your power supply
for CPU power consumption to avoid
causing instability to the system.
