I wanted to test out my old pc,and i didn't notice the voltage switch was at 115v instead of 230.The psu turned on,made weird noise and it was smoking a bit with a smell of burnt plastic.After i switched it back to 230v,it was working completely fine.can someone explain,how did it survive this? Someone told me that i probably fried the transformer which was getting 115v,but i'm still surprised it even turns on and works
