PC shutdown in Endsinger fight

[Yvelaint]

Whenever I am in the fight with Endsinger, my PC shut down and restart when the boss cast the second time "planetes" exactly at the frame where the rocks assemble to a planet.

With try and error I can assume it depends on my Resolution and also my fps, because around and over 90 fps my game crash even at the first planet animation.

Over 2 months ago I bought 2 new Monitors who have a native resolution of 2560x1440 and a maximum of 160Hz.
I played ff14 with the native resolution and with 90 fps to keep a good performance.
and for a period of time until my thread here, I never had issues with any content so far.
But when I entered the Endsinger fight over 5 days ago. It shut down every time at the same frame when the planet assembles from the rocks.

At first I tried all tweakable value that came in my mind lower FPS like 60 fps and the resolution still 2560x1440, it still crashed.

I also turned off Gsync and Freesync feature of my monitor and still crashes.

Only when I tried my old Resolution from my previous monitors, 1920x1080, the Fight against the Endsinger won't crash.

GPU Usage are stable around 40 to 55%, if I can trust my task manager.
The temperature of my CPU and Co are around 40 to 52°c.

My Event viewer showed me that the crashs are "Kernel Power Error 41" and I tried all recommended troubleshooting which obviously didn't work.

For me its utterly strange why only this fight cause such crashs? What is so special on this animation to cause such error?
I really hope there is workaround because its really sad to have such nice monitors but cannot enjoy it because that one fight and maybe future similar fights will cause such crashs.

And about my specifications:

2x LG 27GR75Q-B Ultragear Gaming Monitor
Mainboard: Z390 Gaming X by Gigabyte
GPU: Geforce RTX 2080 Ti
CPU: Intel(R) Core(TM) i9-9900K CPU @ 3.60GHz (16 CPUs)

What's the make/model of your power supply? I'm wondering if it's not quite powerful enough so when the graphics card tries to generate the effect in question, combined with the higher resolution of the monitors, it's trying to pull more power than the power supply can burst up to and then you get the crash.

Greetings Yvelaint,

We apologize for any inconvenience experienced when trying to play Final Fantasy XIV. For us to better assist and look into the issue for you, please respond with the following information:

We would also like to request for a system report. This can be generated by opening the launcher and going to the 'Config' option on the Final Fantasy XIV launcher and to the right of 'System Information' click on 'Display and then copy and paste all the details into a response here.

While we await a response to the information above, we'd also like to suggest some things to try. As previously mentioned by your fellow adventurer, this issue could possibly be a hardware or driver issue as you did mention that setting it back to the 1920x1080 resolution resolved the crashing issue. We'd suggest testing out different video settings to see what possible combination of settings works best or to have it work with your intended resolution. As the error "Kernel Power Error 41" is a general system error for a system closed incorrectly, it may be advisable to check on entries before the event/crash to see if any other logged events may help shed more light on what specifically could be causing it.

We do look forward to hearing back from you so we can assist with the issue accordingly.
