2-5 Connecting Cables
ATX Power Connector
The main power supply connector
(JPW1) on the X6DH3-G2/X6DHi-G2
meets the SSI (Superset ATX) specifi -
cation. You can only use a 24-pin pow-
er supply cable on the motherboard.
Make sure that the orientation of the
connector is correct. See the table on
the right for pin defi nitions.
4-pin and 8-pin Power
Connectors
In addition to the Primary ATX power
connector (above), the 12V 8-pin
connector at J1D1 and the 12V 4-pin
connector at J38 must also be used to
provide adequate power supply to the
system. See the tables on the right for
pin defi nitions.
