This application discloses a power supply
system and a
server. The power supply
system employs at least two power supply components, each including a power supply group and a power supply
backplane. The power supply group is located on one side of the power supply
backplane and distributes power to the compute nodes and switching nodes via the power supply
backplane. The switching nodes are arranged among multiple power supply groups and form positive interconnections with the compute nodes. By distributing power supply capabilities and combining them with the backplane power supply structure, the power supply expansion capability of high-density systems can be improved, the adaptability of the power supply structure to node spatial
layout, heat dissipation, and cabling channels can be improved, the
impact of centralized power distribution can be reduced, and the
system reliability and maintenance convenience can be improved, thereby enhancing the performance of the power supply system.
