The Over Current Protection was very popular implemented on ATX 3.3V/5V/12V switching
power supply. However, the new generation CPU uses different voltage that has regulator to
transfer 5V to CPU voltage (for example, 2.0V), and makes 5V over current protection useless.
This motherboard is with switching regulator onboard supports CPU over-current protection; in
conjunction with 3.3V/5V/12V power supply provide the full line over-current protection.
