if by "vanishingly few" you mean absolutely standard then you are correct. The small PSU I have in my home PC is 1000 watts. I have multiple kilowatt class AC-DC power supplies sitting around for other purposes. There is nothing special about that power level.

For perspective my DC welder is rated at 10000 watts of input. The efficiency is really poor however so I'd only see something like 4000 watts out in the best conditions.
