FFXIV randomly causes my PC to completely shut down/restart

[ZaborgEST]

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€

Its either a power supply issue, (the EVGA Supernova 850 GA and GQ's cannot handle that transient loads that Ampere graphics cards experience.) or you have a semi-faulty 3900X that needs its VTT specified manually because the minimum VID is insufficient for the cpu's asic grade.

AMD's forum also notes this being an issue with Asus motherboards when populating all dim slots

The first half ended up being the problem. I was using an EVGA GQ power supply for my PC that was shutting down my entire system when the GPU would reach the power draw threshold. The strange thing was that it happened more frequently with XIV than it did with anything else.

I ended up completely swapping out my power supply for a Corsair RMx 1000W and it's working flawlessly.
