ATX Power Connector
The main power supply connector
(J1B1) on the X6DH8-G/X6DHE-G
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 cor-
rect. You must also use the 4-
pin (J32) power connector for ad-
equate power supply to the sys-
tem. See the table on the right for
pin definitions.

Connector
In addition to the Primary ATX
power connector (above), the 12v
8-pin Processor connector at J1D1
must also be connected to your
power supply for CPU power con-
sumption to avoid causing instabil-
ity to the system.
