1/2) ATX_12V/ATX (Power Connector)

With the use of the power connector, the power supply can supply enough stable power to all the components on the motherboard. Before connecting the power connector, please make sure that all components and devices are properly installed. Align the power connector with its proper location on the motherboard and connect tightly.

The ATX_12V power connector mainly supplies power to the CPU. If the ATX_12V power connector is not connected, the system will not start.

Caution!

Please use a power supply that is able to handle the system voltage requirements. It is recommended that a power supply that can withstand high power consumption be used (300W or greater). Ifa power supply is used that does not provide the required power, the result can lead to an unstable system or a system that is unable to start.

Please remove the sticker on the motherboard before plugging in while the ATX power supplier is 24 pins; Otherwise, please do not remove it.
