    I wonder, since the M1 Mac Mini is so low power, just 5W for the CPU I read, could it (had it been built differently) run on USB or Thunderbolt providing the power instead of a 110V cable?
    5W at idle, it'll still pull 40W under load.  But yeah, USB could provide that, it already does for MacBooks after all.  A traditional AC power port is probably cheaper and more robust though.
    My M1 is currently using 150 mW (0.15W) at idle. Even as I type this message.

    The 40W you mention might be for the entire mini, not the M1. It might reach 30W, but that would require, all 8 CPU cores, all 8 GPU cores, all 16 ANE cores working at full load, plus all DRAM filled as well.

    Under normal load, the M1 SoC is rated at 10W.
    The 40W is the power at the wall, not the chip. Intel's power ratings are for the chips. There's a test here under load for CPU (rendering) and GPU (gaming) separately where it draws at most 26W at the wall:

    Apple rates it at 39W max and 6.8W idle for the entire machine:

    The SSD needs some power as well as USB ports. For 39W, it would be SSD at full power plus USB ports powering external device and CPU/GPU at max load.

    We're talking about the M1 Mac mini, not the M1 SoC.
