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.
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 specifi cation.
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 defi nitions.
