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).
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.
3/4) CPU_FAN / SYS_FAN (Cooler Fan Power Connector)
The cooler fan power connector supplies a +12V power voltage via a 3-pin power connector and
possesses a foolproof connection design. Most coolers are designed with color-coded power connector
wires. A red power connector wire indicates a positive connection and requires a +12V power voltage.
The black connector wire is the ground wire (GND).
Caution!
Please remember to connect the power to the CPU fan to prevent CPU overheating and failure.
