Just starting a build (my first), and it looks like 270 LEDs from a 60 LED/meter WS2812B strip for a 65" TV. That figures to almost 18A, and I've got a 20A supply. Is the RPi4 going to be too much additional load on the same supply? Would a common ground tie between the PSU and the RPi GND pin be a reasonable solution to run the separate regular RPi USB C PSU? I know that's not best practice. And is there any reason not to just plug the ESP8266 board running WLED into the Pi to power it?
Am I riding to close to the edge?

My supply has an adjustable output voltage, and I've got several multimeter, so that's not an issue. I can set up a star ground using the ground of the 20A supply as the common, since it will have a grounded power cord attached. Does that seem the best way to do it?

You means GND from 5 volts with earth from mains? I would not do that!
I meant, with two power supplies you have to connect both minus to each other.
But as I said, a 20 Amp power supply is more than enough.

I I'm used to working on tube /valve amps and other analog electronics, and have some coding background, but the is my first venture into the world of digital electronics.

No problem. We all started small...
On first start with Hyperion you could have issues with flickering of LEDs or other problems with colors.
Hyperion is not Plug n Play. But it's all a solution of settings.
