When I dipped my toes into vaguely-serious eth mining with GPUs 5 or 6 years ago, I just installed a dedicated 240v, 30a circuit in the basement. The run of cabling was short, the basement was unfinished utility space, and the parts didn't cost very much. It went together quickly.

The business of protecting individual power cords was handled by an Eaton PDU that had a 30a twist-lock plug on one side and a couple of rows of current-limited IEC C13 sockets on the other side.
