Warning
: To avoid damaging your motherboard
and components, please use a power supply
that supports a 24-pin, two 8-pin and one 4-pin
power connectors. Be sure to connect the 24-
pin and the two 8-pin power connectors to your
power supply for adequate power delivery to
your system. The 4-pin power connector is op-
tional; however, Supermicro recommends that
this connector also be plugged in for optimal
power delivery.

the motherboard. These power connectors
meet the SSI EPS 12V specifi cation. These
power connectors must also be connected
