2-5 Connecting Cables
ATX Power Connector
A 20-pin main power supply connector
and an 8-pin CPU PWR connector (JPW3)
are located on the motherboard. These
power connectors meet the SSI EPS 12V
specifi cation. The 4-pin 12V PWR supply
is required to provide adequate power to
the system. The UIO PWR, located at J17,
is also required for the UIO slot. For the
8-pin PWR (JPW3), please refer to the item
listed below. See the table on the right for
pin defi nitions.
Processor Power Connector
In addition to the Primary ATX power con-
nector (above), the 12V 8-pin CPU PWR
connector at JPW3 must also be connected
to your power supply. See the table on the
right for pin defi nitions.
