I'm in the same boat and i rent the place. Both bedrooms are on the same breaker and I'm upgrading my GPU (215W to 415W) and might get a Mi50 as a second card in my desktop for local LLMs.
At full power on both machines i'm already close to tripping the breaker. Witj these new card(s) i don't think it'll fly. My server uses around 700W at max, 450W idle if it's nice and cool in the spare room. Mostly due to loooots of spinning rust. I'm a datahoarder and have a full 18 disk 3.5" JBOD, and 24/25 drives in my 2.5" JBOD.
I'll figure something out I guess...
