Abstract: A power management system and a power management method are provided. The power management system includes a host manager and at least one server. The server communicates with the host manager. The server includes at least one processor, at least one voltage regulator, and a voltage regulator controller. The voltage regulator provides an actual power to the corresponding processor. The voltage regulator controller adjusts the actual power provided by the voltage regulator. The host manager controls the voltage regulator controller in the server and uses the voltage regulator controller to adjust the actual power provided by the voltage regulator for managing a power of the processor.

Abstract: A server system, a server device, and a power supply recovery method therefor are provided. The server system includes a plurality of servers and a power controller. Each of the servers includes an AC power supply and a DC power supply. The DC power supplies of the servers are mutually connected through a cable. The power controller communicates with the servers. When a specific server detects that the AC power supply belonging thereto does not operate normally, the power controller informs other servers of a power required by the specific server, and the specific server controls the DC power supply belonging thereto to obtain powers provided from other servers through the cable, so as to maintain the operation of the specific server.
