From the PSU tier lists found online:
'Older Seasonic Focus revisions (Focus Gold, Focus Plus Gold, Focus Plus Platinum; made before 2018) had transient sensitivity issues. Some new SKUs are not affected because they were released later (Seasonic Focus GM/GX/PX refreshes, Phanteks AMP, NZXT C/E etc.). Although situation with Ampere GPUs is unclear it’s assumed that there are no widespread issues.'
If yours is 4 years old it could well be affected?
Personally I am running a 750W Phanteks AMP which is based on newer revision Seasonic with the 3080FE (max it can pull outside spikes is about 358W) and it seems okay thus far.
