Having two power supplies in parallel will result in overheating the one with the lowest rating. I would just use the 12V from the cab power supply and disconnect the 5V. Of corse this means you need a good USB power supply to provide all that power for the NVME storage.Yes. 2 reasons..
1) my new Astro city was fussy with that “overvolt” at start up. I didn’t want to turn up the output for all voltages to compensate
2) the pi with an nvme instead of micro-std requires more power, and was more than the 5v rail wanted to output.
It was working (but fussy with my particular hardware) on just the cab power & 5v rail until I added the nvme
I’d say having done the NVME addition.. it’s MUCH better than a micro SD, even a really nice quality one. Boots up and loads games much faster, doesn’t stress me for reliability.
I’m a bit of a pi wonk- I modify my raspberry pi installs to minimize lots of linux write access to SD cards to improve lifespan
Anyway this is not a bad solution after all.
