Hello all,
In MSFS 2020 the GPU function, on the source switch, does not work, which is too bad.
I have not bought MSFS 2024 yet, but I saw on YouTube that the TBM 930 has been upgraded with nice new features in MSFS 2024.
Does anyone know if the GPU function works also now? So that you have ground power instead of only the battery which only has a limited amount of power?
If anyone knows, please let me know.
Greetings,

Hello !
I just made the test to be 100%. On the ground, crash bar raised, SOURCE to GPU … the panels light up and live !
It’s hard to see the button is on GPU, but here are small screenshots of the differences in three positions 
Cheers,
K.
Worked fine for me in 2020 and does so too in 20204.
Hello all,
Thanks for your information. But if the switch is in GPU, does it also not drain the battery down? Did you also perform that test? Or is the GPU just a double of the battery in MSFS 2024? So is the battery still drained even when in GPU mode. Because if correctly modelled, that should not be possible then.
And I am not 100% sure what the GPU exactly is on the TBM. The manual talk about a “GPU door”. But is there a door to put the external power plug in then? Or is this an APU generator in the plane even?
Does somebody know for sure what this GPU and GPU Door is exactly?
If anyone knows, please le me know,

Good catch, my test was incomplete. I’ve tested it again, sitting at the door, full lights on, and monitoring the Battery level. On Battery, a few volts (0.5) has been lost in ten minutes. Nothing lost on GPU.
On the ground, no fuel add (FADEC off), when I launch the starter, battery comes out quite fast. And the screen goes off when the battery reach +/-15 volts. The starter is still running. I then stop the starter, goes in GPU : system comes back a 22.2V
I then come back to battery, and see the voltage goes from 22.2V to 21.9 by using the flaps (battery goes down to 21.5 then goes up to 22). None of this happens.
Conclusion : the GPU seems to be a GPU (but invisible one). The battery has a very great cycle of life (although I’m no real pilot and I don’t know how much it’s supposed to live IRL).
The GPU is not modelled on the ELECTRIC SYS page.
For the end of your post : there’s no APU in the TBM. The ability to connect a GPU comes with a small trapdoor, as I recall. I’ve read a manual page of the TBM 940 which says “GPU is not modelled when the door is closed” - it’s not modelled wether the GPU is connected or not, in my sim.
Hello Cowreth,
Thanks for your extensive reply. I guess the GPU is modelled. And I concur with your idea that the GPU is no APU. I thought I read somewhere that there is a GPU door near the baggage door, and I guess that is where you put a ground power plug, which can come from a mobile GPU or the airport network itself.
Thanks again.
Greetings,
Boudewijn
