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
with switching regulator onboard support CPU over-current protection, in conjunction with
3.3V/5V/12V power supply provide the full line over-current protection.
