GPU: PowerColor 8 GB Radeon RX Vega 64 Devil
PSU: be quiet! Straight Power 11 750W

I've changed CPU from 1100t to FX-9590.
I see three possible issues:
1. CPU - I bought it used, so maybe it's not in perfect condition?
2. CPU cooling - NH-D15 supports this CPU and CPU temperatures are good, also case is not the worst I think.
3. PSU is not enough for my system? I recently upgraded from Thermaltake 650W to this Be Quiet! 750W, because it was not enough for Vega 64. But if there is issue with PSU then PC crashes to shut down, but my PC freeze if I run stability test or play more demanding game.
4. Motherboard? It officially supports this CPU.
It would be great if I could be certain about what's the issue.
