The support team has resolved my complaint. New PSU being delivered. Thank you. 
Powers off suddenly. Tried to start up again. Pillar of white smoke smelling like burning plastic comes from the top vent. Powers off again. I unplugged it and ran it outside to a safe location. I opened it up and although the video card was warm to the touch, the smell seems to be originating for the power supply but it's tough to tell. No signs of melting plastic or fire but definitely the worst PC meltdown I've ever seen.  Still under warranty. I extended it only after having a video card issue a month or so  ago where the NVIDIA GeForce RTX 3080 died out and being so hard to replace these days I thought I would bite the bullet and extend it another year. The card was refurbished, so I wasn't too happy about that.  Funny enough my son was playing the game "superhot" when it died. After getting off the phone with support it was determined the video card is dead again. I believe the power supply and/or cables are still suspect. Sending it in for a full diagnostic to the repair center. I have requested factory new parts this time around but no promises could be made.
