2-5 Connecting Cables
ATX Power Connector
A 24-pin main power supply connec-
tor is located at JPW2, and an 8-pin
CPU PWR connector is locatged at
JPW1 on the motherboard. These
power connectors meet the SSI EPS
12V specication. See the table on
the right for pin denitions. For the
8-pin PWR (JPW1), refer to the item
below.
Processor Power
Connector
In addition to the Primary ATX power
connector, the 12V 8-pin CPU PWR
connector at JPW1 must also be con-
nected to provide adequate power to
your processors. See the table on the
right for pin denitions.
