ATX Power Supply Repaired

By on November 27, 2013








Last week my boss brought to me an ATX power supply for repair.


The complaint was no display when connected to the CPU Motherboard.


I found the power supply was very dirty internally once the cover was opened.


The first thing to do is to scan around for any bad component. I saw two bulged main filter capacitors and I believe this was the cause of the problem.


I cleaned the dust and dirt first before replacing the two bulged electrolytic capacitors.



Both the capacitors value was 680uf/200volt. The display appeared once the power supply was connected to the CPU Motherboard. It was an easy repair and does not take much time to finish the job.
