ATX Power Input Connector (CN9)

Steady and sufficient power can be supplied to all components on the board by
connecting power connector. Please make sure all components and devices are
properly installed before connecting the power connector.
External power supply plug fits into the connector in only one orientation. Properly press
down power supply plug until it completely and firmly fits into this connector. Loose
connection may cause system instability.
By default, the motherboard comes with a 4-pin ATX 90 angle connector (CN9) for DC
+12V, +19~24V power input. Co-layout with a 180 angle connector, CN38 (optional).
