ABSTRACT:

SPECIFICATION
BACKGROUND OF THE INVENTION
1. Field of The Invention
The present invention relates to a computer enclosure, and particularly to an apparatus for allowing a computer enclosure to mount a switching power supply in one of two different sizes.
2. The Related Art
A switching power supply in a computer system converts the locally supplied alternating current (AC) power (usually 100-250 V) to a direct current (DC) power at a low voltage usable by the computer. A switching power supply also distributes electrical power to the subsystems of the computer requiring different voltage levels, such as a CD-ROM drive, a floppy disk drive, a hard disk drive or a fan.
As shown in
FIG. 1
, a conventional computer enclosure
10
includes a rear panel
12
defining an opening
14
in an upper portion thereof for mounting a switching power supply
16
therein. The power supply
16
has a socket
18
and a plurality of ventilation holes
20
exposed to the opening
14
. Several holes
22
are defined proximate the opening
14
and are aligned with corresponding holes
24
of the power supply
16
for fixing the power supply
16
to the computer enclosure
10
. A supporting bracket
26
extending from an edge of the opening
14
supports the power supply
16
. However, the conventional computer enclosure
10
can only accommodate a power supply of one predetermined size. Another power supply having different dimensions can not be mounted to the computer enclosure
10
.
Conventional computer enclosures, such as the one shown in
FIG. 1
, can only mount one size of power supply therein. Situations requiring a different sized power supply require a different computer enclosure, which in turn requires different molds and tooling for each enclosure, increasing the cost per enclosure. Therefore, a computer enclosure, which can mount a range of different power supplies by means of a small modification of the enclosure is desired.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a computer enclosure that can mount a power supply in a range of different sizes.
Another object of the present invention is to provide a cover for use in mounting a power supply to a computer enclosure.
The present invention discloses a computer enclosure which can mount a switching power supply of one of two different sizes. The computer enclosure includes a rear panel having an opening sized to mount a first power supply having a larger size, plus a cover covering a part of the opening for mounting a second power supply having a smaller size.
