The present invention discloses a centralized power supply shielding structure of a cabinet-level server, where the structure includes multiple plug-in frames, a power supply copper bar which is configured to supply power to the multiple plug-in frames, and an inner container shielding can. Multiple plugs of the power supply copper bar are correspondingly inserted into the multiple plug-in frames to supply power to the multiple plug-in frames in a centralized way. The inner container shielding can wraps on a periphery of the power supply copper bar to shield the multiple plug-in frames from the power supply copper bar. The cabinet-level server and its centralized power supply shielding structure of the present invention implement a shielding structure for centralized power supply by a copper bar of integration of a frame and a cabinet, which can be applied in an application scene of an open rack and has a simple structural design.
