Power Connectors

A 24-pin main power supply connector(JPW1), two
8-pin CPU power connectors (JPW2/JPW3) and a
4-pin power connector are located on the mother-
board. These power connectors meet the SSI EPS
12V specification. These power connectors must
also be connected to your power supply. See the
table on the right for pin definitions.
Warning: To avoid damaging your motherboard and
components, please use a power supply that supports
a 24-pin, two 8-pin power and one 4-pin connectors.
Be sure to connect the 24-pin and the 8-pin power
connectors to your power supply for adequate power
delivery to your system. The 4-pin power connector
is optional; however, Supermicro recommends that
this connector also be plugged in for optimal power
delivery.
