1,5 month ago lightning struck near my house and it caused my PSU to burn out. I took my PC to a friend and he changed the PSU but with one that is of lower wattage than mine. I don't know for sure, but i think my old supply was 600W. He replaced it with a 450W PSU and said that it should run fine, but that i need to change it as soon as possible. 2 weeks ago i still hadn't changed the PSU, when my PC started to smell of burnt plastic. I turned it off immediately. 1 week after that i had a need of my computer for a task that i couldn't skip, so i had to turn it on for an hour. During that hour i noticed that my PC doesn't smell anymore. So the next day i let my brother play games on the PC, when i again noticed the smells. 2 days ago, my mum brought another PSU, but with the same wattage: 450W. We changed it and again the PC didn't smell. Just yesterday it started to smell again. Today, i opened it and inspected the capacitors of the motherboard and the video card and i noticed no faulty ones. So before i get it serviced, i am asking if the lower than recommended wattage could be the reason for the smell( according to my nose the smell is coming from the PSU), and should i try with a higher wattage supply and skip the payment for the service. Maybe somehow the supply overheats since the components drawing power are too much for it to handle.
