Gold p023-850c3 power supply: It adopts active PFC + LLC half bridge resonance + synchronous rectification + DC-DC architecture, with rated power of 500w-850w. It has passed 80plus gold medal certification, full module wire design and 14cm cooling fan. The circuit structure is mature, the topology is simple, the heating is small, and the DC switch control rejects the pulse current impact. It has the advantages of high efficiency, high PF value and high stability. The design of DC / DC secondary voltage regulator makes the output voltage high precision and small deviation
