Yes it's huge, but not out of the question for some people who go all in on some things in their house.
For example, in my place right now:
- Unifi rack (some switches, cameras, other PoE stuff) - 335W
- Servers (home automation, NAS, etc) - 426W
That's all the time, Unifi actually goes up at night when the IR LEDs come on in the cameras.
