I yesterday used muy computer like always 4 hours in the morning, but in the afternoon I wanted to play for a while, when suddenly I heard and saw a spark, so I turn off the computer, the next morning I remove the power supply, cleaned it and test it in a other old computer, and it worked fine, I have not tested it in mine regular computer. Could have been an excese of dust what caused the spark and the smell, or I need more tests?

The sparks and smell may come ot of the PSU's PCB, the tracks side and more especially parasitic connection between two or more of them because of dust and humidity in combination, for example. If it is cleaned and works fine, use it.
