I agree with centaur78, and recommend that you don't start your computer anymore until the PSU is replaced or ruled out.
The kind of failures you're describing and from the video, not to mention it already possibly damaged a SSD, can cause more damage like: motherboard, CPU, RAM, SSD, HDD, etc.
ThermalTake PSUs don't have good reputation, the one you have is not there best model.
Either borrow a PSU to test with, or take it to a repair shop and tell them you want to test the system with a different PSU.
