Thanks a lot. I have spent the whole day re-doing the cable management. Will try and re-run the sim again tonight and let you know.
then I’ll move down the software route. If everything fails, then I’ll get a new PSU.
As I am typing, everything is pretty stable. I’ll see when I stress the system.
By the way, I have an ITX system and the HDD/ SDD temps are about 40. But the GPU is about 77 Deg with 100% load in MSFS.
