The higher end NVidia workstation boxes won’t run well on normal 20amp plugs. So you need to move them to a computer room (whoops, ripped those out already) or spend months getting dedicated circuits run to office spaces.
Didn't really think about this before, but that seems to be mainly an issue in Northern / Central America and Japan. In Germany, for example, typical household plugs are 16A at 230V.
While technically true, the NEMA 5-15R receptacles are rated for use on 20A circuits, and circuits for receptacles are almost always 20A circuits, in modern construction at least. Older builds may not be, of course.
That said, if your load is going to be a continuous load drawing 80% of the rated amperage, it really should be a NEMA 5-20 plug and receptacle, the one where one of the prongs is horizontal instead of vertical. Swapping out the receptacle for one that accepts a NEMA 5-20P plug is like $5.
If you are going to actually run such a load on a 20A circuit with multiple receptacles, you will want to make sure you're not plugging anything substantial into any of the other receptacles on that circuit. A couple LED lights are fine. A microwave or kettle, not so much.
To clarify, the circuit is almost always 20A with 15A being used for lighting. However, the outlet itself is almost always 15A because you put multiple outlets on a single circuit. You are going to see very few 20A in outlets (which have a T shaped prong) in residential.
