Maybe try to remove one NVME drive (if possible, AMD RAID should be a nightmare, as I heard from LTT) and remove m.2 wifi - it will "restore" enough power to be able to plug in a keyboard at least. Look if problem still occurs. If not, possible PSU, which you were speaking of already Second thing - I do not have it in my mind anymore which BIOS version is "the one to go with" - but 3.70 is def. not the one (outdated AGESA-stack). Still, you may try it out. I'm on 3.60R and some members reporting good results use 3.60S - so yea, you could try those at least you can grab BIOS from the git repo:[URL unfurl="true"]https://github.com/traumfaenger/a300-oc/tree/main/bios-images[/URL]
