Power Connectors

A24-pin main power supply connector(JPW1) and two 8-pin CPU PWR connectors (JPW2/ JPW3) on the motherboard. These power connectors meet the SSI EPS 12V specifi- cation. In addition to the 24-pin ATX power connector, the 12V 8-pin CPU PWR connec- tors at JPW2/JPW3 must also be connected to your power supply. See the table on the right for pin definitions.

Warning: To prevent damage to the power supply or motherboard, please use a power supply that contains a 24-pin and two 8-pin power connectors. Be sure to connect these connectors to the 24-pin (JPW1) and the two 8-pin (JPW2,JPW3) power connectors on the motherboard. Failure in do- ing so will void the manufacturer warranty on your power supply and motherboard.
