It is very popular that the Over Current Protection was implemented on ATX 3.3V/5V/12V switching power supply. However, the
new generation CPU uses different voltages that has regulator to transfer 5V to CPU voltage (for example, 2.0V), and thus makes
5V over current protection useless. This motherboard is equipped with switching regulator onboard which supports CPU
over-current protection; in conjunction with 3.3V/5V/12V power supply to 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.
