Abstract: A system for protecting a power supply includes a power supply unit (PSU), an integrated baseboard management controller (IBMC), and a platform controller hub (PCH). The IBMC includes a receiving module and a comparison module. When the PSU enters a protection mode and is shut down, but the PCH maintains outputting a power on signal to power on the PSU, the PSU continues outputting a power good signal to the receiving module. The receiving module counts a number of times of receiving the power good signal within a predetermined time period, and outputs the counted number of times. The comparison module compares the counted number of times with a reference value, and outputs a control signal to the PCH when the counted number of times is greater than the reference value. The PCH stops outputting the power on signal to the PSU after receiving the control signal.
