ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a desktop computer, more particularly to a desktop computer with an external power supply module.
2. Description of the Related Art
A conventional desktop computer includes an internal power supply module disposed inside a housing of a main computer module for supplying power to a plurality of electronic devices that are mounted in the housing. The greater the number of electronic devices that are in use, the greater will be required power load. Due to the use of capacitors and inductor coils in the power supply module, the size of the power supply module can not be reduced. Accordingly, the size of the main computer module of the conventional desktop computer also cannot be reduced. In addition, when the conventional desktop computer is upgraded, a new power supply module may not fit inside the housing of the main computer module, thereby resulting in inconvenience during assembly.
Furthermore, it is noted that the power supply module in the main computer module generates heat and electromagnetic radiation, thereby resulting in the need to resolve complex heat-dissipating and electromagnetic interference shielding issues.
SUMMARY OF THE INVENTION
Therefore, the object of the present invention is to provide a desktop computer with an external power supply module so as to overcome the drawbacks associated with the aforesaid prior art.
According to the present invention, a desktop computer includes a main computer module, a power supply module and a connecting unit.
The main computer module includes a housing and a plurality of electronic devices mounted in the housing. Each of the electronic devices has a power supply input. The housing is formed with a cable opening.
The power supply module is disposed outside the housing of the main computer module, and has a plurality of power supplying outputs. The power supply module is operable so as to provide a plurality of dc operating voltages at the power supply outputs.
The connecting unit includes a first cable portion, a second cable portion and a male-and-female electrical connector set. The first cable portion is disposed in the housing, and has a plurality of wires connected respectively to the power supply inputs of the electronic devices. The first cable portion extends outside the housing via the cable opening. The second cable portion has a plurality of wires connected respectively to the power supply outputs of the power supply module. The electrical connector set is provided on the wires of the first and second cable portions so as to interconnect electrically the first and second cable portions, thereby respectively providing the dc operating voltages from the power supply module to the electronic devices in the housing of the main computer module via the second cable portion, the electrical connector set and the first cable portion of the connecting unit.
