PC Crash After 1 Hour of Gaming

[dimitzar]

Hi,

I updated heavily my PC last week (see the new spec below) and everything is going pretty smoothly. I am playing AC Odyssey in 4K at a constant 60fps with high/ultra settings, however after about 1 hour of playing, the PC suddenly crashes (I can't do alt-tab or anything, I must reboot). So I am thinking the issue is maybe my PSU which I did not upgrade with the rest, as it was meeting the minimum requirement stated my Nvidia for the RTX 2080Ti. Is this issue really due to the PSU or it is something else?

Here are my specs:

Operating System
Windows 10 Home 64-bit
CPU
Intel Core i7 7700 @ 3.60GHz
Kaby Lake 14nm Technology
RAM
16,0GB
Motherboard
ASRock Z390 Extreme4 (CPUSocket)
Graphics
ROG PG27AQ (3840x2160@30Hz)
3071MB NVIDIA GeForce RTX 2080 Ti (NVIDIA)
Storage
238GB SanDisk SDSSDHP256G (SSD)
931GB TOSHIBA DT01ACA100 (SATA)
1907GB Micron_1100_MTFDDAK2T0TBN (SSD)
Optical Drives
ATAPI iHAS124 F
Audio
SteelSeries Arctis 5 Game
PSU
EVGA SuperNOVA 650 GS 80+ Gold

Thank you

Any help would be greatly appreciated.

It's probably the card. What are your temps while gaming?

 

[dimitzar]

Well the card is new and doesn't show any signs of failure (I know about the RTX 2080Ti reports that some of them are dying but I don't have a blue screen after the crash or artifacts like those buyers whom the card had a problem). The temps are 80 Celsius max.

I really don't see what could be the problem other than the PSU, but I would still like to know what more qualified people think?

 

[dimitzar]

Please, I would really need some advice on what could potentially cause the crashes...

What did you upgrade during the overhaul?
