Question I think my power supply overheated. What to do

[Cabroek]

I was playing marvel rivals when I heard a popping noise and everything shut down and my pc wouldn’t turn back on. I unplugged everything and opened the case and the psu is pretty hot and there was a burning smell. I’m assuming the power supply just overheated. I’ve never had this issue or any issues like it in the past. I did recently install a new ssd(Samsung 870 evo) but other than that everything is the same as it’s been. Could adding a new ssd cause the psu to overheat? What should I do at this point? Should I replace the psu, look into better fans/ventilation, etc. Please let me know your thoughts and recommendations. I’d really appreciate it.

Terrible PSU that you better replace anyway.

Would any psu work or do I need to meet specific requirements? Do you have any recommendations for a new one to buy?

You are likely ok with a 500 watt power supply for the current machine. I would first find a video on how to do a paper clip test on a power supply. Really you also need a volt meter to be sure there is really power output but it should spin the fan when use a paper clip. Real fancy power supplies only spin it for a short time and then stop until the power supply gets warm. You kinda want the power supply to act dead even with a paper clip because if it appears to work then it could be the motherboard that is bad.

The concern is did you damage more than the power supply. If you are going to have to replace other parts like a motherboard you quickly get into the question should you just build new with modern parts since getting old stuff that is no longer manufactured can be kinda expensive at times. You really don't want to buy say a 500 watt power supply and then find out you are going to build a new machine and you need say a 750 watt one.

Would be nice if the specs printed on a power supply could tell you the quality of the parts inside but buying a power supply is almost like buying a black box. Most people error on the side of paying extra to get a well known brand name hoping they use better parts.....even the well know guys make cheap low end stuff you have to be careful of.

A good power supply when it fails should not damage the motherboard. Most better ones have protection circuits that trip off and will reset when you unplug it from the wall.
