POWER MANAGEMENT SYSTEM AND METHOD FOR MANAGING POWER

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. 本发明公开一种电源管理系统及电源管理方法。电源管理系统包括主机管理器以及至少一服务器。服务器与主机管理器通信。服务器包括至少一处理器、至少一稳压器以及稳压控制器。稳压器提供实际功率至对应的处理器。稳压控制器调整稳压器所提供的实际功率。主机管理器控制服务器中的稳压控制器，并利用稳压控制器调整稳压器所提供的实际功率来管理处理器的电源。
