2-6 Connecting Cables

ATX Power Connector

The main power supply connector

(JPW1) on the X7SBA 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

8-pin (JPW2) processor power con-

nector for adequate power supply to

the system. See the table on the right

for pin denitions.

Processor Power

Connector

In addition to the Primary ATX power

connector (above), the 12V 8-pin Pro-

cessor connector at JPW2 must also

be connected to your power supply

to provide adequate power supply to

the system.
