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 (2x4) power connector mainly supplies power to the CPU. If the ATX 12V (2x4) power connector is not connected, the system will not start. If you wish to install a power supply that provides ATX 12V (2x2) power connector, please connect the ATX 12V power connector to the Pin 3, 4, 7,8 of the onboard ATX_12V_2X4 power connector according to the pin definitions. Important Use of a power supply providing an ATX 12V (2x4) power connector is recommended by processor manufacturer when using Intel Pentium D Extreme Edition processor.
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 (400W 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 power supply that provides a
