Persistent burning plastic smell, post- PSU replacement

[ibanezguy998]

So recently I've begun to smell burnt plastic coming from somewhere within my PC. I narrowed it down to be the PSU simply by sniffing around the different components. I recently replaced this power supply with a new one about an hour ago. Unfortunately, this smell is still coming from my computer under normal load (albeit not nearly as strong of a smell as before the new power supply was installed).

Is it normal for this odor to stay in the case for a while? If so, what is the best way to go about getting rid of it?

Well, yes, there are some really smelly components. Just for your peace of mind, check everything for eventual overheating components.
