My build:
CPU: Core i5 6500
Video card: ASUS Geforce gtx 1060 Dual 06 Overclock edition
Power supply: Corsair cx650 (650 watts)
OS: Windows 10 home

Basically, when I play Doom in high detail settings, my computer shuts down. It's as if power is cut off. And then it restarts.

I did some debugging with GPU-Z, enabled logging, and noticed that temps were within reasonable limits. However the crashes always seemed to happen when the core clock hit around 1850 MHz. Consistently, it shuts down when the clock hits this speed.

Drivers and such are up to date. I don't think there's anything wrong with the mobo so I haven't listed it here

I'm a bit puzzled. The decent Corsair 650W PSU should be enough to handle the gtx 1060 running stock.

Certainly the fact that it shuts down when the clock speed hits a certain ceiling tells me the PSU may be defective, despite it being brand new. I don't have a spare PSU.

If I keep the clock speed under 1800 MHz by playing with lower detail settings, my system remains stable.

I strongly suspect the PSU is defective. Any reason to think otherwise? I will probably start with a another fresh PSU.

Try downloading the free version of 3DMark Fire Strike from Steam and run it. If your computer crashes during the physics part of the test that means your cpu is borked in some way.

This just sounds like a cpu problem or a memory problem. When vid cards have issues the system usually blue screens or locks up, but normally doesn't reset/power down.

It could be the PSU like you think, but that card is very power friendly at any stress level. Putting settings to high also increases strain on the cpu too remember. Oddly enough the PSU is the cheapest part to replace depite its size.... But also the biggest pain in the arse.

Debugging a problem like that requires spare parts. If you don't have a second power supply to swap in or a second video card its hard to track it down. One thing you can do is pull all but one stick of memory and then add them back in as you game.
