Power Connectors
A 2 4 - p i n m a i n p o w e r s u p p l y
connector(JPWR5) and four 8-pin CPU
PWR connectors (JPW1/2/3/4) are
located on the serverboard. These
power connectors are specially designed
to support SMCI-proprietary power
supplies. To avoid damaging the power
supply or serverboard, be sure to use
an appropriate SMCI power supply
that contains a 24-pin and four 8-pin
power connectors. Connect these PS
connectors to the 24-pin power connector
(JPWR5) and the 8-pin power connectors
(JPWR1~4) on the serverboard to
ensure adequate power supply to your
system. Failure to do so will void the
manufacturer warranty on your power
supply and serverboard.
