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.

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. AOpen cannot guarantee the protection circuit will always work perfectly.
