PC Restarts while gaming

[sonic_1g]

 

I recently am Facing an issue where if iam playing any heavy games my pc reboots and then has no display.

Specs:

Ryzen 7 7700

Asrock B650

Gpu Rx 6900xt xfx

Corsair vengence rgb 16x2 (rated 6000mhz)

Psu deep cool 850 watt

The ram is set to default 4800mt/s thats another issue it wont go to 6000mhz despite enabling the profiles and setting it manually but it wont work just displays blank boot.

Now the main issue is the pc rebooting whilst gaming , There s no heating issues temps are pretty fine with all components

I tried a few fixes from reditt like:

Updating bios

Having everything on default

Playing with different versions of the adrenaline

Deleting corsair icue ( someone on reditt said it causes issues )

Testing every component individually and combined with OCCT

BUT NO FIX SO FAR

How long have you had this psu for?

I'm thinking PSU at the moment. One thing too for later might be looking at some system logs just in case if its a software glitch instead.
