Identifying Your Motherboard Revision
The revision number on your motherboard looks like this: "REV: X.X." For example, "REV: 1.0" means the
revision of the motherboard is 1.0. Check your motherboard revision before updating motherboard BIOS,
drivers, or when looking for technical information.
Example:

- The 12v power connector mainly supplies power to the cpu if the 12v power connector is not connected the 12v power connector mainly supplies power to the cpu if the 12v power connector is not connected the computer will not start 11
- The motherboard has a 4 pin cpu fan header cpu_fan and a 3 pin system fan header sys_fan most fan headers possess a foolproof insertion design when connecting a fan cable be sure to connect it in the correct orientation the black connector wire is the ground wire the speed control function requires the use of a fan with fan speed control design for optimum heat dissipation it is recommended that a system fan be installed inside the chassis 11
- 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 first make sure the power supply is turned off and all devices are properly installed the power connector possesses a foolproof design connect the power supply cable to the power connector in the correct orientation 11
- Ci chassis intrusion header connects to the chassis intrusion switch sensor on the chassis that can detect if the chassis cover has been removed this function requires a chassis with a chassis intrusion switch sensor 12
