To make this function works, you have to enable it in the system BIOS, connect this header to a sensor somewhere on the chassis. So, whenever the sensor is triggered by lights or the opening of the chassis, the system will send out beep sound to inform you. Please be informed that this useful function only applies to advanced chassis, you may purchase an extra sensor, attach it on your chassis, and make a good use of this function.

The RTC (real time clock) can also keep running as long as the power cord is plugged. If you lose your CMOS data by accident, you can just reload the CMOS configurations from Flash ROM and the system will recover as usual. ATX Stand-by Power Battery Auto Switch Auto switching to ATX standby power as RTC (Real Time Clock) 00:00:00 long as AC power line is plugged. This smart design can increases battery life if you still had battery plugged on motherboard. Flash ROM CMOS Backup by EEPROM 50 MK77M / MK77M II CP U O v e r - c ur r e nt P r ot e c t i on Online Manual Over Current Protection has been popularly implemented on ATX 3. 3V/5V/12V switching power supply for a while. However, new generation CPU is able to use regulator of different voltages to transfer 5V to CPU voltage (for example, to 2. 0V). This motherboard is with switching regulator onboard that supports CPU over-current protection, and it applies to 3. 3V/5V/12V power supply for providing full line over-current protection. 5V (Protected by power supply) ATX Switching Power Supply 3. 3V (Protected by power supply) 12V (Protected by power supply) Onboard Power Regulator Over-Current Protection Circuit CPU Core Voltage Note: Although we have implemented protection circuit try to prevent any human operating mistake, there is still certain risk that CPU, memory, HDD, add-on cards installed on this motherboard may be damaged because of component failure, human operating error or unknown nature reason.
