I assume that the prototype boards are being run off of modern productized supplies
I'm not too sure. I took a couple of screenshots of the prototype board in action.

those appear to be some sort of unit - I think I saw one being used/explained in a video somewhere.
In the opening of Adrian's X16 video it appears he's using a standard power supply -

I probably need to update this thread now that my Breadboard 6502 "X16 Compatible" is nearing completion, after adding the audio components, the power consumption shot WAY up. Currently at 4MHz with both VERA and YM2151 generating audio, I'm measuring 500mA - or about 2.5W. I don't have the tooling to measure component-by-component to see where all that power is getting consumed, but it jumped after the Audio, OpAmps, and DACs were added. The YM2151 is warm to the touch (not hot, but not room temp either) so I figure that's one major culprit.

Some solid numbers.
? That's still less power than a modern USB power adapter will supply (the current norm is > 2A for Apple and Android units, with Power Delivery units able to go much higher.)
I use one of these on my MiSTer, fed from a 19.5v laptop power adapter:

Recently I needed some compact PSU, I found some and I decided to share, because I think these might be some good options for X16.
1. Usual Pico PSU:
https://www.amazon.com/Mini-Box-picoPSU-160-XT-Power-Mini-ITX-Supply/dp/B005TWE6B8 2. Something like Pico PSU, also powers from external brick, but board is bigger, and delivers more amps (Chieftec Adapter + DC to DC SERIES / CDP-120ITX):
https://www.chieftec.eu/products-detail/193/Adapter___DC_to_DC_SERIES 3. ATX internal PSU box, but smaller in size then usual (Chieftec SMART SERIES / different models from 250W to 400W):
