Well, I found the problem:

that was the PSU connector that powered the 3080. I used an Y splitter to get 3 ports powered but that was a stupid idea because I wasn't aware of the fact that unlike on linux, in windows clocks and powerlimits might reset which results in the rig pulling max wattage.

In that case, a 3080 with 320W TDP is too much for a single PCIe 8Pin cable that specifications are capped at 288W

Lucky me, it is just the PSU and not the whole rig or even worse, my whole house...

yep I have a lot of simple mining rigs or linux the clocks do not runaway, 1 or 2 times in 5 years with hundreds of cards involved.

I have a hand full of windows rigs (5) and over the years with under 100 cards used maybe 35 runaway clock drops to top power.
