These are designed more for customers in the EU that already have that in every room. The US power system in inferior unfortunately 🙁
While my mansion was built around 1830, all power circuitry is rather ordinary 1980's.
Yes, that started at 220V, has been yanked up to 230V as part of EU alignment, and yes it's 16A on the breakers: but in my case there are only three such circuits for an entire floor. So if somebody starts a washing machine or a hair dryer, poof goes a gaming rig that uses this PSU at full throttle.
120V may be somewhat unfortunate, because it's definitely enough to get you killed but not enough to run three gamer rigs on the same circuit. I'd say the main disadvantage vs 230V is overall much more copper and power loss in those cables.
But most households in Germany include at least one three-phase line, at 400V these days, which used to be required for electric ovens and cookers. Unfortunately they are mostly wasted these days as neither modern household appliances nor gamer PC are able to take advantage of them.
When I was a kid plenty of countries still had both, sockes for 110 and 220V e.g. in Italy and perhaps France, but nothing beats the klunkers they still have in the UK: those look as if you could run a freight train on them!
