The main power supply connector
(JPW1) on the X7SBU 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 connector
for adequate power supply to the
system (See 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 CPU
PWR connector at JPW2 must also
be connected to your power supply.
See the table on the right for pin
definitions.
