AFAIK that 3A figure for the Pi includes power for the USB ports on the Pi. So if you don't load up the USB ports, you can get away with more like 1.5-2A, depending on what you do.

Thanks. I intend to use it as a cluster ski no need for USB peripherals, I'll keep that in mind!

FWIW my 4GB RPi 4 pulls about 1.2A peak when using the CPU full tilt. Haven't stressed the GPU yet so don't know about that. This without any USB except wireless Logitech keyboard/mouse receiver, and with Wifi enabled.

Useful information thanks. That's much lower than the recommended 3A.
