Since the GPU has high performance requirements for Electrical Date Peak Processing (EDPP), the 12V preset voltage corresponding to the output of the two output terminals B can be used for the four back-end network cards of the server and the PCIE interface. Graphics processor power supply. Using this method for power supply can provide higher output capacitance protection, and at the same time, the design of two outputs can isolate the power supply of two GPUs in two channels.
