A power protection system for a power supply includes a power unit, a microcontroller, a connector, a current sensing resistor, a hot-swap controller, and an electronic switch having first to third terminals. The first terminal is connected to the connector through the current sensing resistor. The second terminal is connected to the power unit. The third terminal is connected to a control pin of the hot-swap controller. First and second sensing pins of the hot-swap controller are respectively connected to two ends of the current sensing resistor. A monitoring pin of the hot-swap controller is connected to the second terminal. A clock pin and a data pin of the hot-swap controller are connected to two terminals of the microcontroller.
