ATX Power Input Connectors (CN30 and CN70)
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.
For better compatibility, we recommend to use a standard ATX 24-pin and 4-pin power
supply for these connectors. 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.
