Hi guys
I have one of these ATX PSU Analyzers/Analysers Tester
https://www.aliexpress.com/item/3280...73275478%22%7D
The analyzer is very good for testing ATX power supplies - if they work! But it's pretty useless for testing them if they faulty. Which kinda defeats the object.
The problem is caused by the fact the Analyser is powered from the 12V on the 20/24pin ATX connector. So for example if you have 5V Standby and nothing else, the analyser is dead, it does not power on. Even worse you can have all voltages present apart from 12V and the analyser still will not power on - leading you to believe you have a dead PSU.
I recently wasted over two hours trying to fix a 'dead' PSU where I just could not find anything wrong, only to realise in the end it was working, apart from an open circuit track on the 12V output
So I decided to modify the Analyser so that it will power up and work if any voltage is coming out of the ATX PSU, whether it is 5VSB, 3.3V, 5V OR 12V
In fact it will now work with just 2.5V on any one voltage rail
The modification cost just €0.70 in parts and fits inside the existing housing.
If you have one of these analysers and would like to make it actually useful, then here is how I did it
