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, IDE, 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.
