My computer overheated and powered off, powered on again, PSU sparked and turned off, what should I do?

So, I was playing The Witcher III with my R9 280 while I was mining with nicehash on my 1070, suddenly the computer turned off, then I just thought It happened because overheating (as I have an amd 8120 and the r9 280 wich are pretty hot components at full load), it wouldn't have been a new thing to me because it had happened to me before (the PC turning off due to overheating), so, I waited like 10 minutes for the computer to cool down, I turned it on again, and the PSU literally sparked... I smelled and checked every component and all seems to be ok EVEN the PSU after all of that didn't smelled like it burned. So, what should I do? I don't really have money right now to get any new components, and I was pretty much depending on mining as my primary economical resource... Should I just wait some more time for the PSU to cool down or should I just throw it away and don't risk my components. Any ideas?

The Supernova NEX has its fair history of issues: https://hardforum.com/threads/evga-supernova-nex-750b-destroyed-my-computer.1798758/

If it were me: I would stay the heck away from that PSU and get something like a 550W/650W SeaSonic/Corsair unit. If mining is your primary source of income, then you should protect your investment. It's not worth the risk/bit of money saved. Power must be pretty cheap for you to be making ROI with those specs.

That PSU is dead.
Hopefully, it didn't kill off anything else as it died.

Do not plug it into anything except the recycle bin.

You need a new PSU...a good one.
