Power Connectors

A 24-pin main power supply connector(JPW1),
two 8-pin CPU power connectors (JPW2/3)
and two 4-pin power connectors (JPW4/5) are
located on the motherboard. These power con-
nectors meet the SSI EPS 12V specification
and must be connected to your power supply to
provide adequate power to the system. 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 4-pin and two 8-pin power
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 connectors are optional; however,
Supermicro recommends that these connectors
also be plugged in for optimal power delivery.
