A power distribution system is adapted to a management module connected to a plurality of servers, each of which is varied in power consumption in response to a power mode and performance thereof, via a power allocation request line and a power allocation response line. The management module records the upper-limit power setting, the power allocations, and the power pool with regard to the servers. The server records the power mode, the power allocation, the upper mode request threshold, and the redundant power which is calculated based on the difference between the power allocation and the actual power consumption. The management module recovers the redundant power from the server so as to update the power pool. Upon receiving a power allocation request, the management module distributes at least a part of the power pool to the server, thus allowing the server to shift the power mode to the upper mode.
