Most likely either the power supply or the VRM on the mobo.  Of course, check the obvious--loose power connectors, including the power cord to the PC.

Connections seem ok… Is there anyway to test the power consumption on the PSU or just a general check for issues.

There are consumer-grade PSU voltage testers, but they generally only give you the ability to spot a hard fail, e.g. a dead or sagging bus.  If it's something that only trips under load, that wouldn't help.  There are PSU load testers, but that's an expensive test instrument that you'd typically only find in a computer repair shop.  If you have a reputable repair shop nearby, perhaps having them test it would be an option, although with shop rates being what they are, I doubt it'd be much cheaper that just buying a new PSU.

I've had the uncommanded shutdown thing several times before, and once it was a bad VRM requiring a mobo replacement, and once it was a PSU heading south.  I've since overbuilt my systems w/r/t power supply and regulation, and haven't had that issue since.  By that I mean I use PSUs rated at 50-100% above my highest expected load and motherboards with heavy-duty VRM circuitry.

If it were me, I'd start by borrowing or acquiring another PSU and swap that out, as it's the highest probability cause.

kernel error 41 critical error (The system has rebooted without cleanly shutting down first).

MSFS after the update may be pushing your system harder than anything before it. I believe a system stress is in order as recommended by others.

Since SU5 I’ve been been getting a complete shutdown.

happens to me as well after SU5 and hotfix. an RTX 3090 can easily draw 500 Watts if not power limited, versus the default Nvidia FE version 350 Watts. depending on your power supply, you might just have hit its protection level. check your power supply's wattage, I would recommend 850 watts minimum for an RTX 3090 with Intel Core i9 or higher. I assume SU5 can require more power from GPU and CPU concurrently than the versions before depending on graphics and slider settings. increase GPU power draw through your GPU overclocking tools and check with GPU benchmarks how far your psu can go until pc crashes.

benchmarks: Superposition or gpu-z

I plan to get a 1.000 Watt psu, ready for nextgen RTX 4000 GPU series, which will require yet again higher power. you don't even have to be overclocking your CPU or GPU to crash the pc, an underpowered psu has the same effect. my interim solution until I get a stronger psu will be to reduce maximum power load via EVGA Precision X1 tool down to 350-400 watts maximum.

Agree with w6kd..

PSU .. you will have to monitor power draw while playin to see if you can replicate the issue.

If your not overclocking your cooling may still be an issue so i would monitor temps as well.

Update - Just tested Forza an it shutdown on me so yes must be hardware then.. I’ll go with a power unit swap out like you suggested.

So looks like I’m grounded for a few days, not a bad time really considering the carnage.

thanks for the help everyone.

We can have a beer together. I am waiting all of this out before my fresh install. IPA's OK?

Sounds good to me!… good luck with your install buddy.

I just put my system on a 1000 watt battery backup UPS.    I have an Intel 10900k,  Z490 motherboard,  3090,  32gb ram,  2x m.2 SSD's,  a Schitt USB DAC,  and USB stick/hotas/pedals / TrackIR / Logitech switch panel / Logitech auto pilot panel.    My power supply is pulling over 660 watts from the UPS line filter when just sitting still in the FS20 hangar.   I have a 1000 watt psu.

Add in my 48" Oled,  cable modem,  and wireless routers,   and my entire system is drawing a total of 752 watts from the UPS just sitting there in the hangar.    War Thunder does the same thing,  high power draw in the hangar.   I guess that's why you're starting to hear people talk about consumption.

And remember what Bob said, an oversized PSU by a large margin is the way to go.  And buy a good brand. This is the component which feeds everything else. It cannot be the weak link.

Good advice… I’ve got a 750w already which I thought isn’t bad considering my PC is nothing to write home about, 4790k 1070.  I’ve had it about 7 years now though original mobo/psu so maybe it’s just time to replace.

750W should be ok for 4790K/1070 ....

Folks - it is not only the Watt consumtion. You have spikes or peaks in milliseconds - your standard monitor software will not be able to measure it and you will never get notice of it - except your PSU will shut down or reboot. Modern PSU's are more effected by this - overdimensioning is the best solution.

Best regards

Yes,sounds like your Power Supply is borked.

I agree. BeQuiet is a very good premium brand for power supplies, and the one I am using, they come with a 5 year warranty:

Silent Power supplies for your PC from be quiet!

here you can easily calculate your required power requirements:

"isn't bad" also depends on brand. low cost no-names often use low-cost components especially the capacitors, they can dry out over the years. there could also be dust collected inside.

But I would first empty or rename the COMMUNITY folder to be sure you don't load incompatible mods. many are now incompatible with SU5 and the newer hotfix and they can cause crashes.

power supplies can deteriorate over time, I would strongly recommend a brand name, my recommendation is the be quiet! Straight Power 11 ATX 1000W, costs some 170 €, 5 year warranty.
