20-pin Proprietary Power
Connectors
There are two 20-pin main power supply
connectors (JWR1, JWR2) 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 nitions.
Also refer to the layout below for the
PWR connector locations.

Note 1:
You cannot use both 20-pin power connectors located at JWR1
(the right connector) and JWR2 (the left connector) as input power supply
connectors 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 pro-
prietary PWR Connectors, please customize your PWR cables based on
the SMC 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.)
