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 12V 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.

Note: Although we have implemented protection circuit and tried to prevent any human
operating mistake, certain risks might still happen when CPU, memory, HDD or add-on cards
installed on this motherboard is damaged due to component failure, human operating error or
other unknown natural reasons. AOpen cannot guarantee that the protection circuit will
always work perfectly.
