4080 Founders edition users, Do you have any issues with flying the Fenix aircraft and Kernel power issues?

Hi people, as the title suggests, I'm looking for some feedback from 4080 Founders edition (non super) users regarding pc stability issues whilst flying the Fenix Simulations aircraft.

For the past maybe six weeks or so, I've been driving myself demented with a Kernel Power issue which ONLY occurs when flying either of the two Fenix Simulation aircraft and wondered if anyone has had any similar problems and even better, found a solution. I have opened a ticket with Fenix regarding this but I feel it would be beneficial to have at least some input from the community. I have flown two long hauls at present on both systems, one on each with the 777-300 from PMDG and one on each system with the PMDG 737-800 and have not been able to replicate the issue with these aircraft. My community folders on both systems are clean, the Fenix aircraft are both installed on the same drives on both systems to eliminate the possibility of a failing drive (M.2 SSD's used in both systems) and None of the world updates are currently installed on either system.

Additionally, this fault occurs no more than 200nm from the departure airport ( regardless of location).

The issue specifically I have been having is this:

Event 41 - Kernel-power.

Task category (63)

Keywords (70368744177664),(2). (The fault on both systems is identical and provides virtually no explanation other than "The system has rebooted without cleanly shutting down first").

A quick google search has revealed that this issue occurs when essentially the power supply is unable to deliver any more power to meet the demands of the system.

To combat this, I Have replaced my power supply, I have reseated, meticulously cleaned and rebuilt the system, all of my drivers are up to date, Fast boot is disabled, game bar and game mode are disabled on both systems, no overclocking of any kind is present on either system, I have completely reset the pc and freshly reinstalled windows, the simulator and the Fenix aircraft and still have the same issue. I've gone as far as to run memory function tests which resulted in no errors, I have tested this on an entirely separate system which has an identical GPU which oddly enough, produces the same fault.

My specs are - 7800X3D, 4080 FE, 2x24 Crucial pro DDR5 6000's and an 850W Power supply.

The other system - 12700K, 4080FE, 4x16 Crucial pro DDR5 6000's and a 1000W power supply.

With this post, I don't want to suggest that theres an issue with the Fenix aircraft, more to find out if anyone has run into similar problems. Any useful feedback I will include in any conversation with Fenix about this issue.

Edit - it is probably worth noting that this issue does not occur on any other games to include cyberpunk 2077, the entire Battlefield series, X-Plane 11/12, DCS world and a huge variety of other games. I also have an arsenal of aircraft to test to include the TFDI MD11 and BAE 146.

Second edit - wrong processor.
