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.

My empire of dirt is basically nothing. I’m using low powered computers, mostly fanless. The watt meter on the main power bar is like 15W.
40 watts normal up to 60 watts. That includes modem and router. PC is fanless system.
~500 watts continuous.
late but i think i lose the thread. The entire house runs at slightly over 1.5kW, and self hosted equipment accounts around 1.2kW of that. The daily cost is only about £2 though due to solarand batteries.
The NAS itself probably takes most of the power, which isnt logged. My server is a Raspberry Pi 5, so used 1.86kWh in September.
Around 1000-1200 watt continuously. Still our electricity cost is less then 0.
Anyway my old 11gen dell power edge servers cause the biggest power draw. But I am not ready to upgrade them due to the current memory shortage.
Mine draws around 15-20 watts. I’m mostly using low-power hardware: a Rock 5b as my main server, a 2tb nvme ssd, a 2tb hdd and a Glinet travel router (fine since i live in an apartment).
My NAS/home server takes about 180 kWH/year, or 20W on average (costs me about 5 Euro/month). This feels like a lot to me and makes up a good chunk of my total energy usage.
What I did to optimize it is mostly select a “low-power” x86 platform, and limit the number of disks. I also decided not to use TrueNAS because it couldn’t let the disks from going to sleep.
The machine hosts 10 TB of usable storage (+RAID 1), syncthing, immich, file server, Influx DB, Grafana, and a few other services.
Yeah I use Unraid for multiple reasons but being able to spin down disks when not in use was a big factor. I have 6 mechanical drives totalling 56TB of usuable storage so it was important to me they don’t all need to be on at the same time. TrueNAS also comes with some other headaches, I like being able to drop in whatever disk I need to for expansion or replacement.

I didn’t move that far away (to Debian + ZFS), so that limitation still remains. Although the addition of Raid-Z expansion should alleviate things quite a bit.
I am using a Raspbery Pi 5 8GB as my NAS & homeserver. It is quick and performant enough while having an idle power draw which is not really noticeable on your electricity bill. Very happy with it.
Most of my stuff lives on a cheap hetzner vps so that power is someone else’s problem lol. at home it’s a raspberry pi that’s always on (a few watts) and a bitaxe miner doing about 19W, that’s around 14 kWh a month, like 3 euros here. the gaming pc is the only hungry thing and it stays off, the pi wakes it with wake-on-lan when I actually need it. took me a while to get the bios settings right (erp off, power on by pci-e) but it was worth it.
is mining worth it for you?
I’d say no more than 15W.
1x Jetson Nano
1x SSD
3x 2.5" HDDs
1x RPi 3B wih PiholeUsed to be 200watts bang on but the latest round of updates bumped it up to 210Watts. Everything is on a UPS and I pull measurements from that into an RRD DB (because I like to make my own stuff). It’s kinda cool to see how heavy disk use or CPU intense tasks will increase power draw by up to 50W, or some times or when the power drops off sharply I know my NVR container is not working because 6 ffmpeg tasks all stopped at the same time.

RRD
That’s a name I haven’t heard in a minute!
I see the rrdtool gallery is still up and my graph is still in there 🤭. (No it’s not the Christmas graph, that one’s insane.)
I’m using Influx nowadays but maybe I should revisit good old rrdtool for old times’ sake.
Like 3-12w but I’m only running a little mostly jellyfin server
3 Lenovo Tiny’s, one HP Mini, 3 external drives, a switch and 2 modems runs just under 100W.
I worked good out a whole ago, so here’s a copy and paste:
I have a power monitoring plug on this setup, so I can tell you exactly how much!
CPU: 2 x Intel® Xeon® CPU E5-2680 v4 @ 2.40GHz
RAM: 512 GiB DDR4 Multi-bit ECCMy disk layout is like so:
This draws a fairly consistent 650W, including a POE router (15.6kwh per day). My current electricity price is 39.38c/kwh… HOWEVER I have a cheap rate of 8c/kwh between midnight and 6:00am, and free power between 11:00am and 2:00pm. I also have solar which tends to cover ~10:00am to ~2:00pm, but its dependant on sunlight so I’ll ignore it for now.
So:
12:00am-06:00am = ($0.0800/kwh * 0.65kw) * 06 = $0.312
06:00am-11:00am = ($0.3938/kwh * 0.65kw) * 05 = $1.279
11:00am-02:00pm = ($0.0000/kwh * 0.65kw) * 03 = $0.000
02:00pm-12:00am = ($0.3938/kwh * 0.65kw) * 10 = $2.559Total = $4.15AUD per 24 hours, or $1,514.75AUD per year
My Merross plug is showing that I’m currently averaging a daily consumpion of 15.021kwh, and I’m not accounting for the hours of solar offset so the actual dollar value will be a little lower. But still. Fair few bucks.

What apps are you running?
Public facing services (via Cloudflare + NPM + fail2ban):
- Immich (around 575,000’ish / 3.5TB photos 50,000’ish / 3.0TB of videos)
- Nextcloud (around 500GB or so of shared work photos/documents, then another ~2TB or so of auto uploads user from mobile)
- Plex/Jellyfin/Emby all sharing from the same ~100TB library.
- Navidrome for just music, though I actually prefer Plex Music now.
- Paperless with the usual tika/gotenberg for OCR (around 50,000 documents, lots of technical manuals which means search is very handy to find codes/part numbers quickly). Also imports from my work email so any purchase orders or invoices get saved, and anything the office scanner scans gets automatically imported too.
- Archivebox for archiving websites (pretty crap now tbh)
- Bentopdf for editing PDF files (super handy!)
- Chhoto for my own short URL service (super handy!)
- Convertx for file conversions from anything to anything pretty much
- MeTube for downloading clips from FB/YT/etc
- Nginx for an image hosting website I made many many years ago (kinda like Imgur but 15 years ago) with a few hundred GB that still get referenced in forum links on occasion (I see links to files from 2011 still active in the logs)
- Pingvin for sharing large files
- SearXNG for when I get sick of Google bubbling me
–
Non-public facing:
- Kopia to back up my home server to my work server, and vice versa
- Crashplan for a(nother) remote backup on someone elses hardware
- Syncthing as a way to keep photo directories on laptops and what not backed up to the server
- The classic *arr stack (sonarr, radarr, lidarr) with qbit/sab behind gluetun
- An assortment of scripts to do things that are useful.
For example I record my VOIP calls to WAV files which get emailed at the end of a call. There’s a script that logs in to my email account and downloads any recorded files, transcribes it with Gemini, then posts it to Discord with a summary of the call at the top, a transcription of the call, and then stats at the bottom (source number, time and date of call, duration).
Another one is a webhook via the VOIP provider - when someone rings, the webhook calls a script that downloads my shared phone book (or falls back to the last downloaded copy if it times out after 2 seconds), matches the incoming number to the phone book, and adds a Discord notification for the person who’s ringing. The Discord notification saying who is ringing and where they are from (and any other notes) pops up basically at the same time as the first ring is received.
Also for whatever reason I set up an Arduino for the entry buzzer on our workshop and it sends Discord notifications when the buzzer is turned on/off via timer or by the manual override. I did have it set up to record entry/exits but turns out that got real spammy, real fast.
