## Abstract

A power supply includes a main body, a fan, and a mounting bracket. The main body defines an opening therein. The mounting bracket for mounting the fan is detachably mounted to the main body to cover the opening. The fan is mounted on the mounting bracket and received in the main body through the opening.

## Claims

### Claim 1

A power supply comprising:
a main body defining an opening therein;
a mounting bracket detachably mounted to the main body to cover the opening; and
a fan mounted on the mounting bracket and received in the main body through the opening;
wherein the fan comprises a shell and a plurality of blades mounted in the shell, four corners of a side of the shell each define a first mounting hole, the mounting bracket is substantially rectangular, and defines a plurality of groups of first through holes arranged in a cross from a center of the mounting bracket to four corners of the mounting bracket, four first fasteners extend through one group of the first through holes of the mounting bracket and the first mounting holes of the fan to mount the fan to the mounting bracket;
wherein four corners of the mounting bracket are recessed to form four recessed portions, each recessed portion defines a second through hole, the main body comprises a bottom plate, and a lateral plate substantially perpendicularly extending from a side of the bottom plate, the opening is defined in the lateral plate, four mounting pieces are formed on four corners of the opening, each mounting piece is recessed from the lateral plate, and defines a second mounting hole, four second fasteners extend though the second through holes of the mounting bracket and the second mounting holes of the mounting pieces of the main body, to mount the mounting bracket to the main body.

### Claim 2 (depends on 1)

The power supply of claim 1, wherein each first fastener is made of elastic material, and comprises a shaft, a fastening portion extending from one end of the shaft, and a tapered flange extending from a circumference of the shaft, the shafts with the flanges of the first fasteners extend through the first through holes of the mounting bracket and the first mounting holes of the fan, the fastening portions resist against the mounting bracket, and the flanges resist against the side of the shell.

### Claim 3 (depends on 1)

The power supply of claim 1, wherein a circuit board is received in the main body, and supported on the bottom plate, a connector is installed on the circuit board to be electrically connected to the fan.

### Claim 4 (depends on 1)

The power supply of claim 1, wherein the mounting bracket defines a plurality of vents.
