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 main board. 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 main board 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). If a power supply can not provide the required power, it very possibly leads to an unstable
system or a system that is unable to start. If you use a 24-pin ATX power supply, please remove the
small cover on the power connector on the main board before plugging in the power cord. Otherwise,
please do not remove it.
