Abstract

The present invention relates to computer power supply circuit and is one kind of computer with LCD adaptor power supply output. Inside the chassis of the computer, there are DC power supply interface for LCD and integrated LCD adaptor power supply and computer power supply. Via connection between the LCD DC power source interface in the computer power supply and the DC power source input interface in LCD, DC power source may be supplied from the computer power supply to the LCD without outside LCD power supply adaptor. The present invention is saving in cost and power consumption, has small volume, high overall efficiency, convenient operation, etc.

Description

technical field [0001] The invention relates to a computer power supply, in particular to a computer with LCD adapter power output. Background technique [0002] The liquid crystal displays used in the existing computer market are all powered by low-voltage direct current. There are two forms, 1. An independent AC power adapter power supply, 2. The AC power adapter power supply is built into the liquid crystal display. The above-mentioned two forms of DC power supply for liquid crystal displays convert AC power into low-voltage DC power through secondary exchange. The disadvantages of this structure of power supply are: occupying a large volume, low efficiency, and high cost. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a computer with LCD adapter power output, which saves cost, saves electric energy, reduces heat consumption, does not occupy extra space, and is easy to operate and use. [0004] The solution...
