Connecting Cables

ATX Power Connector

There are a 20-pin main power
supply connector(JPW1) and
two 8-pin CPU PWR con-
nectors (JPW2/JPW3) on the
motherboard. These power
connectors meet the SSI EPS
12V specification.

Processor Power Connector

In addition to the Primary ATX
power connector, the 12V
8-pin CPU PWR connectors
at JPW2/JPW3 must also be
connected to your power sup-
ply. See the table on the right
for pin definitions.
Warning: To prevent damage to your power supply or motherboard, please
use a power supply that contains a 20-pin and two 8-pin power connec-
tors. Be sure to connect these power connectors to the 20-pin and the two
8-pin power connectors on your motherboard for adequate power supply
to your system. Failure to do so will void the manufacturer warranty on
your power supply and motherboard.
