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