Many Amigas also have a Raspberry Pi inside them these days, for the PiStorm accelerator, which increases the +5V current requirements a fair bit.

Is the pi usually on it's own power supply?

Not with the PiStorm32 Lite that I've got.

Seemed to run OK with a Pi 4 on an original Commodore PSU, or at least nothing appears to have blown up or melted when running it for short periods.

Maybe I'm pushing my luck, but then again, back in the day, you'd often be running an accelerator board, hard drive, and a couple of floppy drives from that same PSU, so maybe it's up to the job.
