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 mainboard. 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 mainboard 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 recommemded 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 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
motherboard before plugging in the power cord ; Otherwise, please do not remove it.
