1/2) A T X J 2 V I 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 A T X J 2 V 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). If a power supply is used that does not provide the required power, the result can lead tc an
unstable system or a system that is unable to start. If you use a power supply that provides a 24-pin
ATX power connector, please remove the small cover on the power connector on the motherboard
before plugging in the power cord; otherwise, please do not remove it.
