Recently had a burning smell coming from my PC despite still working all fine. Also clean PC, minimal dust although i have cleaned again after this. problem is everything now smells of burning but seems strongest from the PSU (Corsair CX750). Opened the PSU up and cant see anything wrong, all capacitors seem fine although one coil on the side the wires output from seems to have some odd yellow staining. should add it turns out the PSU has been upside down for the last 3 years and the fan has been facing the bottom of the case where theres no vent (woops) although this smell has literally only occurred today (to note it wasn't intentionally upside down, just only realised now after inspecting it). Buying a new PSU to be safe but my question is, A) is it normal for the smell to make every other bloody component smell the same? and B) does anyone have an idea what the problem is, ie. if it is the PSU, and if it is, why now?
Another thought, the PC has been considerably louder since upgrading my CPU, Mobo and Ram a fair few months back although its usage is still under that of the PSU.

PS.would a Corsair RM550x be a good replacement?
