Abstract: An AC/DC power bank distribution management system is provided, which includes a power supply unit, a power distribution board and a power distribution unit. The power source includes the alternating current (AC) or direct current (DC) that is converted into a low-voltage DC by a high efficiency power supply unit. Then, the power distribution board adjusts the transmission mode for providing a direct current with safe, stable and low-voltage. Thus, for the AC/DC power bank distribution management system, the power consumption value refers to a real power consumption usage value in the server system operator which can provide a fair electricity data for the telecommunications system operators and the server system to save the electricity expenses for the server system.

Abstract: An improved fixing structure for power supplies defines an accommodating area on a power supply for installing a fixing structure, and the power supply has a fixing hole on a casing of the power supply defining a limit fixing condition for the fixing structure when the power supply is pushed into the casing, and the power supply has a limit hole for installing a limit fixing member to restrict the displacement of the fixing structure, and constitutes a fixing structure that can be installed directly inside a power supply without occupying additional space, and attains the effects of fixing two fixing structures and limiting the fixing member.

Abstract: An improved power supply device for a computer system conforming to the specifications of PS/2 type includes a back-up power supply. A partition plate defines at least one set of compartments in a case and at least one set of power supply units is disposed in the compartments and connected with a power-control panel installed in the case. Each terminal edge at one open end of the case is bent inwardly to form an attachment portion; and a plurality of predetermined fastener-receiving portions is formed in the attachment portion. By the abovesaid architecture, the power supply device can be installed fixedly in a computer system by mounting fasteners to the fastener-receiving portions to thereby build a space spacing power supply device.

Abstract: An electrical power supply assembly includes a base member, a cover member connected to the base member to confine a space, at least one partitioning plate disposed between the base and cover members to divide the space into a plurality of side-by-side adjacent compartments, a plurality of rails disposed on the base and cover members and the partitioning plate, a plurality of electrical power supply units slidably disposed inside the space and having slide members held slidably by the rails, a rear cover attached to the base and cover members, an electrical circuit board mounted on the rear cover and electrically connected to the power supply units, and an electrical control box disposed outwardly of the space and connected to the base and cover members and the rear cover.

Abstract: A stacked container assembly includes a variable number of stacked modular containers, and an engaging unit and a fastening unit provided on each container to permit the containers to connect with one another. The container assembly holds an electrical power supply assembly which includes a plurality of electrical power supply units respectively received inside the stacked containers, and an electrical control device electrically connected to the electrical power supply units and received inside a control box mounted on the top or bottom of the stacked containers.
