摘要：
A power supply, an over voltage protection (OVP) apparatus, and an OVP method are provided. The present invention employs the OVP apparatus for monitoring a core power. When a voltage level of the core power is higher than a reference voltage, the OVP apparatus disables a power supply unit. As such, the present invention is adapted for avoiding damage to a capacitor of a conversion unit or load caused by abnormal boost of the voltage level of the core power.
