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.
ATX Switching Power Supply
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.
