I have an old Corsair Hx850 that I bought around 2011-2012, recently moved it from a Sandybridge 1155 setup to an X99 setup with a 3090 GPU, no problems at all, runs perfectly.
To be honest I did not even think about not using it until I read this topic, now I am wobbling !
No worries, I prefer to be aware of the potential issue and have a spare EVGA 1300W PSU that is only a few years old.
If my wobble gets severe I will swap out the Corsair HX850 for the EVGA 1300
