I recently bought a Vega 64 gpu, I have been having a problem for about 2-3 months, its fan throttles up and the screen goes black I have to force restart always, it's almost a totally new gpu so I don't think it's a gpu error. I tried 3DMark, 4k stress test, for about 10 mins it's tottaly okay, nothing happens but after then the issue is there, sometimes the issue happens att 200 watt, at 220 watt etc, the issues happens in games too, e.g. apex legends or blair witch, but e.g. borderlands 3, the new grid, star wars jedi fallen order, nothing these games run perfectly, I bought 2 days ago a new psu (1300 watt, gold) the issue is still there, so it was not the psu, but I had a 1920x1080 144 hz monitor, there was no error, when I bought a 2560x1440 monitor the issues appeared, now I set power saving mode in AMD Wattman, it solves my issue but my gpu can take up only 166 watt at most.
