My hardware is:
- MSI MPG Z390I Gaming Edge AC Mini-ITX Motherboard
- Intel Core i9-9900K 8-Core, 16-Thread, 3.60 GHz, 5.00 GHz Turbo, 16 MB Cache
- 32 GB (2x 16GB) Corsair Vengeance LPX 3200 MHz DDR4 RAM
- INNO3D GEFORCE RTX 2080 TI GAMING OC X3 Graphics Card (I also use the Inno3D TuneIT app to adjust the clockspeed, and temperature target)
- Silverstone SX800-LTI 800W SFX-L 80Plus Titanium PSU. (My mistake, it’s not 850W)
The reason why I thought it’s related to temperature was because when I built this PC the first time, I built it into a small form factor Mini-ITX case. In it, I get frequent crash to reboot whenever I play heavy games like Final Fantasy XV or Dragon Age Inquisition. So when I decided to move into a new larger case (Micro-ATX) using the exact same hardware but also upgrading my CPU Cooler to Noctua NH-D15, I stopped getting those crashes again on the same games.
