ATX Power Connector
The main power supply connector
(JPW1) on the X7SBi 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 (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 Pro-
cessor connector at JPW2 must also
be connected to your power supply
to provide adequate power supply to
the system.
