20-pin Proprietary Power Connectors
There are two 20-pin main power supply con-
nectors (PWR1, PWR2) and a 4-pin auxiliary
power connector (JP10) on the motherboard.
These power connectors meet the SSI EPS
12V specifi cation. For power supply to work
properly, please follow the instructions given
below. See the table on the right for pin defi ni-
tions. Also refer to the layout below for the
PWR connector locations.

Note 1:
You cannot use both 20-pin power connectors: PWR1 (the right
connector) and PWR2 (the left connector) as input power supply at the
same time. Only one connector can be used for input power supply to
the motherboard at a time. For proper use of these proprietary PWR Con-
nectors, please customize your PWR cables based on Supermicro PWR
Connector Pin-Out Defi nitions listed above.
Note 2
: The black square (dot) on a power connector indicates the loca-
tion of Pin 1. (See the pictures below for the power cable connections.)
