Your CPU isn't dying, it's fully loaded in game. You're hitting 100% PPT power limit (which is set at 76W to make the 5700X a 65W TDP chip) and running 4GHz+ across all eight cores.
What is your game resolution and quality set at? Are you running these low on purpose to try and maximize FPS?
Are you running any other processes while gaming? Have you tried closing other unneeded apps while gaming?
Increasing the PPT limit could raise the clock speed a bit (at the cost of increased temps) but looking at that motherboard it isn't built to handle it. (only 4+2 phase power, no heatsinks and a single 4-pin CPU connector) So your best bet is to reduce the load on your CPU.
