My PC keeps turning off when playing high graphical games, how do I fix this?

Last year, I bought a new RTX 3060 as a graduation gift to myself. However, my PC would shut off whenever I played high-graphical games such as Cyberpunk. I suspected that my power supply unit (PSU) couldn't handle the power draw required by the GPU. To verify that it wasn't an issue with the new GPU, I ran FurMark ROG to test for artifacts, which confirmed that my GPU was fine. I had experienced similar issues in the past, which were resolved by upgrading my PSU. So, I upgraded my PSU again and bought a Corsair RM850e. This fixed the issue with lower-intensive games like Valorant and Dota, but the problem still persisted when playing Cyberpunk. I tried using Corsairs PC-builder tool and it recommends a lower-watt PSU ( 650 Watt). So now I am back to thinking it's my PCU again. Is there a way to test out my PSU?

EDIT: I ran Furmark again but this time ran the CPU burner and It turned off, so either the CPU is drawing too much power ( which I don't really see happening ) or it's getting too hot and it trips the PSU.

My Specs:

CPU: AMD Ryzen 7 2700

GPU: ASUS Duel GeForce RTX 3060 OC Edition 8GB

MB: MSI B450 gaming Plus Max

PSU Corsair RM850e

It does sound like a CPU thermal shutdown. What are you CPU temps running at in game? What cooler do you have?

Right now when playing cyberpunk its sitting between 85-90c, and its just the generic fan cooler that came with the cpu

That's pretty warm, max temp is 95c. You said it shuts down. Does it turn itself back on or stay off?

Stays off

Thermal shutdown is very likely then. I think I'd take care of the CPU temps first. Zen+ wasn't meant to run on the edge like Zen3 and later. I think I'd get a good cooler to control the thermals. You can get the DeepCool AG400 for $25.99 as an example. 120mm tower cooler, it'll definitely handle the thermals on that CPU.

Only other possibility is a power shutdown, but something would have to trip the board or PSU. If that was happening and it was tripping the PSU you might here a 'click' when it happened. MSI usually overbuilds their VRM, I wouldn't think that would be an issue.
