Dell Optiplex 5090 SFF random shutdown while gaming
I have a Dell Optiplex 5090 SFF with warranty till Feb 2025. It has Core i5 11500, 32 GB RAM, RX 6400 Graphics Card. I am trying to play Flight Simulator 2020. Previously this game use to work fine. When am trying to play this game after long time now, the CPU temps are going in range of 85-95 deg. GPU - 85-90. After playing game for few minutes when I go to in game menu the system shutsdown. I have checked Windows event logger details but have not found any information. I have raised this to Dell support that my CPU temperatures are going really high. They have agreed to change the CPU cooler. I am not sure it's cooling problem or problem related to PSU.

Random shutdown can be due to insufficient psu power.
if your stock psu is 200w it could be an issue. 5090 sff comes in 300 or 200w
agree cpu gpu temp are on the high side. SFF is just not great for gaming. Open case side panel and use a desktop fan to blow cold air on cpu/gpu for a test. If temp were cause of shutdown this test would prove it

The systems comes with 300w power supply. This has been happening only recently.
I raised this to Dell customer care. They sent a technician who changed the CPU cooler and thermal paste.
Post this the CPU temperatures are in range 75-90 while gaming. Reaching 90 only some times. But again during testing the same issue happened where the system would just turn off.
The technician asked me to remove the GPU and use the onboard graphics for gaming. While using onboard graphics this issue did not happen.
The technician agreed to change the PSU and the part has been ordered. It seems like whenever the power demand increases above a certain threshold the PSU is tripping. It is expected to support loads upto 300w but my system can only reach peak wattage of 220-250w. (CPU - 70-80w, GPU - 70w, 2 SSD - 20-30w, NVME - 5w, 2 RAM - 10w, CPU cooler - 5-10w, extra 80mm fan - 5w)
I will update if changing PSU resolved the issue.

The RX 6400 is only 53w. Definitely shouldn't have been a power issue, meaning the problem shouldn't have happened. Those RX 6400's can run on 200w PSU's. With the 5090 being an SFF, heat may still be an issue. Smart getting a 300w PSU by the way. :)

psu calculator estimate i5-11500 + RX 6400 if NVMe ssd + HDD + DVD
Load Wattage:233 W
Recommended PSU Wattage:283 W
if sata ssd + NVMe ssd + DVD
Load Wattage:225 W
Recommended PSU Wattage:275 W
if two sata ssd + NVMe ssd + DVD
Load Wattage:228 W
Recommended PSU Wattage:278 W

Here is the update:- Got the PSU replaced from Dell and the issue was still happening. Dell asked me check with GPU company since they think the shutdown is not due to Motherboard, PSU, RAM, CPU.
Next I connected the GPU by keeping it outside the case via GPU riser cable. Now the temperatures from GPU are in range 75-78 degrees under 2K resolution and Ultra graphics and it does not shutdown. Have been running game for last 1-2 hours and the issue just does not happen. I did notice previously that as soon as GPU temperatures go above 85 degrees the shutdown was happening. The GPU is still under 1 year warranty, planning to contact the technical support for GPU since I think it's a GPU issue.
