What is your self hosted power draw? (lemmy.world)

Selfhosters what is the power draw of your entire setup? And have you done anything special to manage it you'd like to share?

Including all network equipment I use around 110kWh of good ol' 120V 60Hz USA juice per month. Averaging about 215 watts of power draw for my systems. Nothing amazing, but I like to think that it's a conservative setup for everything I accomplish with it. I'm paying around $25 a month for my setup. None of that includes my work PC or personal PC, just hosting infrastructure.

Other than trying to make sure all power states are available on my server I haven't done a lot of power conservation.

I'm curious what you all have.

I can trip the measly 15 amp breaker by drawing 1.5kW on two servers + turning on an amplifier that is somehow on the same circuit despite being in a different room quite far from where my servers are lol.

On average though I only draw like 350W. The huge spike only happens if I run a miner/llm on both of my servers or the during the startup spike.

The 1kW chunk comes from some RTX Quadro 6000s which each eat 250W each when maxxed out.

EDIT: Want to mention that most machines report their power draw (from mobo) without IPMI, so you can use your favorite stats collector use it to form a rough estimate of kWh total in case you don't have a proper meter that records usage.

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...
