Describe your problem. List any error messages and symptoms. Be descriptive.
Having a nightmare with a current build, has been working great for about 6 months, but now it powers off randomly.
I've been doing a small amount of research and people are mentioning it's likely the PSU, and I should be upgrading from a 750W to a 1000W for the RTX 3080, as power supplies degrade over time and my current one probably doesn't meet the insane power draw the 3000 series requires.
Does anyone have any input on this? Here are some of the posts I've looked at:

List anything you've done in attempt to diagnose or fix the problem.
I've checked Event Viewer for errors, the only one I find is this, which has been consistent with the times of the shutdown:
Event 41, Kernal-Power - The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.
I have checked PC temps both under and off load and they do not exceed 58° C in Furmark.

Provide any additional details you wish below.
The PSU I've seen recommended the most is the Corsair RM1000x, is that any larger than the SF750?
Because of the SFF style case, changing the PSU requires a new set of cables. Do you have any recommendations, if changing the PSU is in fact the problem?

Yo, I had this issue for 1 year (no kidding). I finally fixed it today and I am literally going through Reddit to share the information.
What and why it happens; 3080 Spec says that it consumes 650W.
When its W draw is measured at 1ms, it seems to be right, but when the time scale change to 1/100ms (10microsecond), it occasionally spike up to like 800, 900W. The voltage stays around 600 for the rest 99/100ms, so when the voltage is measured in ms, it is convincing that 3080 consumes \~650W. However, your PSU shuts down as soon as the GPU draws 900W in that 10 microseconds.
Long story short, you need to under-volt your GPU

My current setup; 1850MHZ @ 850mV. (haven't tested 1900mHz@887mV)
I was not able to play 1 round of R6 (usually shut down in 30 seconds after loading), I just played 4 rounds with no problem. Not sure if my PC will shut down after hours of playing R6, but This looks promising.

What was the necessary undervoltage? Even after 80% of my attempts, it still shuts down.
