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, 1.475V), 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 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 guaranty the protection circuit will always work perfectly.
