Connecting Cables

20-pin Proprietary Power
Connectors
There are two 20-pin main power
supply connectors (J17, JP10) and a
4-pin auxiliary power connector on the
motherboard. These power connectors
meet the SSI EPS 12V specifi cation.
*For power supply to work properly,
please refer to the notes 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 J17 (the right
side connector) and JP10 (the left side connector) as input power supply connec-
tors 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 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 location of Pin
1. (See the pictures below for the power cable connections.)
