Over Current Protection has been popularly implemented on ATX 3.3V/5V/12V switching power supply for a while. However,
new generation CPU is able to use regulator of different voltages to transfer 12V to CPU voltage (for example, to 2.0V). This
motherboard is with switching regulator onboard that supports CPU over-current protection, and it applies to 3.3V/5V/12V power
supply for providing 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.
