Hi Albert,

great report, very instructive. Only one question. How do you knew that D503 was a zener? . Was it because the negative was connected to the positive of the capacitor or cause it's mission on board it's to maintain the voltage to the 5V put of the ATX?. Please could you recommend any power supply tester and explain basically how it works?

Thank you all for your kind comments! The ATX 410 Watt Power supply in this
article came from my previous workplace were we fixed Laptops (mainly BGA
chip Hotfix problems) and other Consumer Electronics. We probably had
abused this Power Supply Unit to find Bad Capacitors on Computer Mainboards.
The high shorting current most likely had destroyed it in the end. With the
5V or 3.3V outputs we were able to find hotspots on Mainboards on positions
that would be destroyed by 12V or higher Voltages. Capacitors that got hot
were the bad ones with an undesired low resistance.

In reply to Humberto.

Yes indeed Humberto. And it is just amazing how easy most
good designed Power Supply Units can be repaired at no significant
cost at all. And a good day to you too!
