Abstract

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.
