I have a problem and I have no idea how to fix it. All games are launched and playing at 1080 60 fps + without any stutters and freezing. I don’t have any problems, but the other day I decided to install the AC Odyssey and after starting the game a black screen appears and the computer restarts. In event viewer shows error kernel power 41. I decided to try the driver version 19.7.5. The game started, in-game benchmark passed on ultra settings at 60+ fps, but when it starts a new game it throws it to the desktop. I tried reinstalling various kinds of windows, installing drivers through the remote control on the video card, trying to identify problems with RAM, scanned the disk, updated the BIOS ... nothing helps.

Your RX5700XT is a reference blower right? What are the temps like? If they are high then likely more current will be used by the GPU.
You should not have to run the GPU off PCIe2.0x4.
You can do a search and you will see:
Kernel Power 41 error in Windows 10 [ULTIMATE GUIDE]
Running at PCIe2.0x4 will reduce GPU performance and therefore reduce FPS which reduces power consumption.
If the game has an FPS Limiter, set that to a reasonable level.
If not then try running FRTC to keep FPS from spiking too high.
As a last resort try running Radeon Chill with Chill_Min set as low as possible = 30, set Chill_Max to 300. Turn off Profile FRTC. Set Global FRTC to ~1 FPS below your monitor refresh rate or the FPS limit you want. Then launch the game from the game profile in Radeon Settings. Do not use the Radeon Overlay to change CHILL_MAX. You will very likely find that it will kill your Keyboard only input FPS, but Chill might be able to keep RX5700XT reference GPU temps down to stop power input problems. Rapid mouse movement should lock to Chill_Min = 30, or Global FRTC limit. The mouse locking behaviour is random in Chill.
