2-5 Connecting Cables
ATX Power Connector
There are a 24-pin main power sup-
ply connector(JPW1) and an 8-pin
CPU PWR connector (JPW3) on the
motherboard. These power connec-
tors meet the SSI EPS 12V specifi ca-
tion. The 4-pin 12V PWR supply is
required to provide adequate power
to the system. See the table on the
right for pin defi nitions. For the 8-pin
PWR (JPW3), please refer to the item
listed below.
Processor Power Connector
In addition to the Primary ATX power
connector (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.
