> All of the Seasonic power supplies that go beyond 1kW or so will trip my shitty (i.e. probably defective) Siemens AFCI breakers. Not even the same circuit all the time.

I don’t know much about US electrical standards but aren’t your residential circuits rated for 1800w or 2400w? Here in New Zealand they are 2400w and people regularly plug in 2400w fan heaters without issue.

Yes it wouldn’t be pleasant running this 24/7 in summer in any living space. But you could install a heatpump with 7kw of cooling capacity which should handle it (adding to the electricity bill).

The residential AFCI issue I describe isn't about the wattage directly. It's about transient currents generated by large switch-mode power supplies being detected as arc faults. Similar concern as with induction motors.

That is interesting. In New Zealand AFCI is only required on 20A sub circuits in places that have a high fire risk, contain irreplaceable items, school sleeping areas and some other minor circumstances.

In the US the National Electric Code caps draw at 80% of rated load. So a 15A circuit is permitted a 1440W load even though it should handle 1800W.

Crazy. Our hair-dryer has 2kW.
