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.

Claims

1. An improved power supply device for a computer system, said power supply device being arranged to be disposed in a computer system to provide a back-up power supply, comprising:

a case including a partition plate which defines at least one set of compartments;

a power-control panel disposed at one end of the case, and terminal edges at another end of the case;

wherein each terminal edge at another end of said case is bent inwardly to form an attachment portion, and a plurality of predetermined fastener-receiving portions is formed in said attachment portion; and

at least one set of power supply units disposed in said compartments and connected with said power-control panel; and

wherein said inwardly bent attachment portion is arranged to receive fasteners for fixing said power supply device in said computer system by assembling fasteners to said fastener-receiving portions for building a space saving power supply device.

2. The improved power supply device for a computer system as claimed in claim 1, wherein a mounting portion is arranged on one end of each of said power supply units at a position corresponding to said fastener-receiving portions and arranged to be secured to said fastener-receiving portions by said fasteners for fixing said power supply unit in said case.

3. The improved power supply device for a computer system as claimed in claim 1, wherein a positioning pin and a positioning hole are respectively disposed at corresponding positions on said power supply unit and said power-control panel for fixing said power supply to said control panel.

4. The improved power supply device for a computer system as claimed in claim 1, further comprising an air frame including a plurality of vent openings and secured at said one end of said case;

and a shield board with a plurality of heat dissipation holes located between said power-control panel and said compartments.

5. The improved power supply device for a computer system as claimed in claim 1, wherein one set of guideways and one set of slide tracks are respectively disposed at corresponding positions on an inner wall of said case and on an outer wall of said power supply units respectively at corresponding positions.

6. The improved power supply device for a computer system as claimed in claim 1, wherein one set of heat dissipation fans is arranged at one end of said power supply unit, and a plurality of heat dissipation holes at the other.

7. The improved power supply device for a computer system as claimed in claim 1, wherein a power input port, and ON/OFF switch, and a set of pilot lights are disposed on each said power supply unit.
