For better compatibility, we recommend to use a standard ATX 24-pin power supply for this
connector. Make sure to find the correct orientation before plugging the connector.
ATX_12V_2X4: ATX Power Source Connector
The connector provides +12V to the CPU power circuit. If the CPU power plug is 4-pin, please
plug it into Pin 1-2-5-6 of ATX_12V_2X4.
Note
» Before you power on the system, please make sure that both ATX, ATX_12V_2X4 and connectors
have been plugged-in.
» Insufficient power supplied to the system may result in instability or the peripherals not functioning
properly. Use of a PSU with a higher power output is recommended when configuring a system with
more power-consuming devices.
