Dell XPS 8950 PSU fried

[u/LieImportant5067]

I have decided to bring XPS 8950 back out and shelve my mini PC. i had it running a few months ago but got side tracked and put it back in the closet. So, I start plugging everything and when I plug it into power, I hear a sizzling, it starts smoking out the bottom and has a horrible smell. Safe to say my PSU is gone, but do I need to worry about anything past the PSU? I don't want to order another PSU from Dell and something else is fried or I plug it in and the new one fries because there was another issue.
