Power Connectors
A 24-pin main power supply
connector(JPWR3) and two 8-pin
CPU PWR connectors (JPWR1/2)
are located on the motherboard.
These power connectors meet the SSI
EPS 12V specifi cation. These power
connectors must also be connected to
your power supply. See the table on

Warning: To provide adequate
power supply to the motherboard,
be sure to connect the 24-pin ATX
PWR (JPWR3) and two 8-pin PWR
connectors (JPWR1, JPWR2) to the
power supply. Failure to do so will void
the manufacturer warranty on your
power supply and motherboard.
