The present application discloses a system for controlling power supply redundancy of GPU server, including power supply redundancy module which includes first and second PSU, BMC, CPLD and GPU module which includes plurality of GPUs. The first PSU is connected to the CPLD by first bus, and the second PSU is connected to the CPLD by second bus. The BMC is connected to the CPLD by first I2C bus and second I2C bus, and sends heartbeat information to the CPLD. The CPLD is connected to the BMC by third bus and fourth bus, and the CPLD is connected to the several GPUs by third I2C bus. When the BMC is abnormal or restarted, the CPLD may control the overall power consumption of the server, it may be ensured that the server will not crash, and the loss of users caused by the BMC being abnormal or restarted will be reduced.
