FFXIV randomly causes my PC to completely shut down/restart

Thanks for the input. Can it also be relevant even if I didn't have problems before? I've used this setup quite a while.

I also tried underclocking GPU today, I used the max possible "-" setting and I was able to play for a while, hopefully it is a temporary fix.

Issues can suddenly manifest and many of them do so across a Power cycle with silicon electronics, the underclock of the gpu does point towards a degradation there but in doing so you're also limiting how much the cpu is doing by proxy, you might try downgrading to 472.12 or upgrading to 511.23.

If you're one of the many that employ undervolting to reduce gpu temperatures, this can manifest issues suddenly with device age and driver updates too.

I'm still a bit confused, how only FFXIV can affect this, like I can play any other game with ultra-hyper graphics and nothing ever crashes. It makes me feel like this is more like a software issue. Also, today the game crashed quite fast even with the underclocking, I wish I could somehow determine that it is 100% the PSUs issue and nothing else, so I could try replacing it. I could totally understand if other games also crashed, then I wouldn't have any questions on this regard.

games load the hardware in different games, FFXIV tends to be more cpu bound in group content which will result in more variation to the GPU load(65-100% for a GTX 1080@1440p60 on a first gen i7), this means the asic voltage is constantly variating in a way it wouldn't if the chip was only moving between 90 and 100% load.

Shadow of the Tomb Raider for example on a (pair of?) 3090's was shutting down a 1000w PSU due to this variation in device draw despite it not occuring with both cards loaded with furmark

the new world crashes on 3090's was due to this same variation in power draw, except the variance was exceeding the capabilities of the chosen buck converter leading to overshoot and thermal runaway(melting).

Hey again. I have now changed the PSU and the crashes are still happening. Also I have discovered that it's not related to FFXIV, FurMark crashes almost instantly as well. Also older drivers make no difference at all. So it must be the GPU which is dying?

must be, thats horrible in this GPU market

Yea, I'm considering RTX 3070 Ti, which is whopping 1,2k€
