This work pursued as a goal to make a principal research about new systems of supply of processors with technology ATX. Currently all PC produced and marketed in the world meet the standard ATX. It was necessary given the lack of documentation and information about these systems technique to perform a job that would determine the methodology for testing and repair.

Through the method of engineering reverse was possible to determine the principles of the basic work sources switched the system ATX and obtained a methodology for testing and repair them. You managed to make a documentation that serves as a guide for troubleshooting or school materials for the knowledge of these.

the issue of atx power is part of the work of research and development to be held in the microcomputer unit department of automation and systems minint.

To power the electronic equipment from the network power sources are required to convert the alternating voltage network in one or more direct voltages stabilized at its output while providing isolation of the output with respect to network food for reasons of security.


The power supplies are an integral part of all electronic equipment they may even be multiple sources of power all different within the same system. For example if you have a printer a monitor and a processor we will have a total of three sources. Furthermore these sources are all switching and can be totally different not only in their designs but also in their capacities and physical sizes.
