I recently finished building my PC: https://nl.pcpartpicker.com/list/y6JmGq .First motherboard came in with an error, had to RMA it, now everything looks to run smooth, no problems when the GPU doesn't perform under stress.
Once the GPU runs full power and goes to 70 celcius (max fans, max power), my screen turns black with the message that my monitor lost its signal (display port channel). I've read topics that the main issue is the PSU (Got some regrets getting the gigabyte Aorus 850w instead of a crossair one), But its also possible that the 2080ti is the problem (it ran fine the first 2 days though).

Is there any way to test the PSU?
Ive tried changing the DP cable, using the second DP slot on the GPU, all with no fix. HWMonitor shows the PSU +12v rail at 12.192 V. Any tips are welcome to see which component is causing the error.

(Using MSI Afterburner to use 50% power limit prevents this error, but it limits the performance)
(Yes, all 3 8-pin cables are PCIe ones, not cpu cables)
(I also replaced the DP cable and tried the second DP slot with not result)
Edit: Also got latest Nvidia drivers

Edit 2:
CPU-Z shows 1 * 6-pin and 2 * 8-pin. Shouldn't this be 3 * 8-pin?

log file of GPU-Z when GPU is going full power (once at 70°C, it shuts down (inside the case, the fans of the GPU keep spinning, lcd screen shows 70°C and still circles to show other statistics of the momeny it shut down).

Seems the error occurs when fans use more than 50% of their full speed. Can't see anything else.

Can you check Windows event logs for logged errors?
What is your current PSU? see >>Posting Guide<<

If you apply on the fly GPU reference clocks, does it still crashes?

Sorry, my bad. I will post components below and edit the main post:

Board: MSI MEG x570 ACE
BIOS: 7C35v1B
VGA: MSI 2080ti Lightning Z
PSU: Gigabyte Aorus P GM 850W
CPU: Ryzen 7 3700x

HDD/SSD: Gigabyte Aorus NVMe Gen 4 1tb

Just done some more tests by increasing fan speed of the GPU to 100%, started the game CoD Warzone on maximum graphics and was playing without any problem. GPU didnt exceed 73 celcius. What is interesting in this log, is the wattage usage of the GPU chip power draw. The entire session, the power does not exceed 200W, it remains stable between 185W and 195W. Even after reverting everything in MSI Afterburner it was doing well, so i rebooted Windows.

I tried again without touching MSI Afterburner this time, power consumption of the GPU chip power draw shows numbers well over 200, ranging from 202W up to 243W (way higher than previous session without errors). This session crashed, after 29 seconds using over 200W (the GPU should be able to handle this much though, unless it exceeded 100% power usage upon crash, unable to monitor this)

No weird event logs in the Even Viewer of Windows, besides one of an unsafe way to reboot the system (as the GPU crashed)

Got it,

have you done this?:
yes, i tried adjusting MSI afterburner midgame to see what could trigger the issue. Thank you for helping me btw :)
(I think you mean this with GPU reference clocks on the fly)

I made 2 logs:
Log 50% power:
Starting with 50% power in afterburner and -502 memory and cpu frequency. I could boost both back to 0 in small steps without the issue. at -502 the game had around 70-80fps. When back at 0 boost it had 100-110fps. When turning up the power back to 65%, fps went up to 114-120. As soon power consumption got turned back to 75%, the GPU crashed within 10 seconds. (It crashes once it hits +/- 70-75°C, where after the fans start spinning at 100% speed, monitoring LCD screen keeps circling with its latest known statistics and all lights on the GPU keep glowing.)

Next log i tested with -502 frequency in Afterburner, while leaving power consumption on 100%.
Log 100%:
Frequency still on -502 on both GPU and Memory, while power consumption remained on 100%. The GPU crashed as soon it hit the 70-75°C mark

Edit: included both log files made with TechPowerUp GPU-Z

Can you test the card in another PC?
Have you tried a different GPU drivers?
Can you try to switch to the 2ndary BIOS chip to try?

This is the only pc i have with a 850W power supply. Also the CPU/motherboard does not have a second onboard GPU, the 2080ti is the only GPU to output display.

I haven't tried other GPU drivers, only the latest (Version 456.71, game ready driver)

try older GPU drivers
also try switching to second vBIOS chip then retest.

A few months ago I had MSI GTX 1080 ARMOR and got troubled with no signal on display/monitor also the fans were at 100% while the card was not in full load, then I tried to re install NVIDIA driver via DDU, after that I did not have any issue for a few weeks, btw I already sold the card. Maybe first you could try to re install driver card via DDU in safe mode.
