Two power connections on the X11SSH-TF must be connected to the power supply. The
wiring is included with the power supply.
• 24-pin Primary ATX Power (JPWR1)

Main ATX Power Connector
The primary power connector (JPWR1) meets the ATX SSI EPS 24-pin specication. You
must also connect the 8-pin (JPWR2) processor power connector to your power supply.
