About 80 W. I do Folding@Home

My servers (3U) in the DC pull ~400w but my provider doesn't do power/traffic billing just a flat fee ~230€
For my homelab if I power up my backup server pull a backup and then write it to tape and my gf is gaming it's 900w
Idle is like 150w

Something like 25W at idle for the single server I operate. I'm not counting networking because I'm using the equipment that I already have and need just to distribute internet at home.

7 or 8w idle for the server. Comes to about 10eur per year. I couldn't justify using more without feeling like a hypocrite who also advocates for energy conservation.

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 ECC

My 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 = $2.559

Total = $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.

Oh true. It's a 8 bay NAS with 5 spinning drives. And 2 nvmes The gaming PC is an i7 12th gen with 63GB ram and a 3070ti.

3 Lenovo Tiny's, one HP Mini, 3 external drives, a switch and 2 modems runs just under 100W.

1,514.75AUD per year

What apps are you running?

Cool setup, i used to have an 8th gen tiny lenovo pc. Pretty powerful for its size.

Nice

What hardware are you running?

Like 3-12w but I'm only running a little mostly jellyfin server

Is this daily, monthly? Cause otherwise you'd be drawing 144kw from just a nas which is.... beyond silly

11th gen i3 NUC, headless Debian.

Used 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.

• 1x T330 with 4 disks and 2 dozen services.
• 1x H340 NAS with 2 disks
• 1x PoE switch
• 3x PoE cameras
• 2x Desktop switches
• 1x Desktop router
• 1x Cable Modem

My rack server uses 150W idle. Granted that's 2 processors and 48 cores, 256GB ram, and 8 case fans that you can't cycle less than 35% even though they don't need to be anywhere near that high.

I'd say no more than 15W.
1x Jetson Nano
1x SSD
3x 2.5" HDDs
1x RPi 3B wih Pihole

A lot of UPSs will have power metering as well if you're not already on one.

Yeah they're amazing value, got them for 150 each with 32GB RAM right before the AI craze. It's sixth gen i7 processors and they're perfectly fine for everything I'm throwing at them.

I am, and it does, that's how I got the 300-400w estimate. It is connected to the NAS and shuts it down gracefully when power goes out. Wonder if the NAS can also read the power usage over that cable. Might just be easier to use a $15 zigbee plug though to get the data directly into Home Assistant.

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.

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.

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.

What's a good smart plug to use?

I assume it's a thing you place between the machine's power cable and the wall and can be queried over WiFi?

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.

I use Home Assistant, and prefer Z Wave or Zigbee, as those are gaurenteed to not call home and not rely on a third party server. Third Reality makes some pretty good stuff. And yeah, it'd go between the wall and my server rack.

It seemed like the easiest way to store multiple years of data in a format that wouldn't change or disappear.

I found it super easy to work with as a never-went-to-school programmer (in the rime before claude).

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).

is mining worth it for you?

Hardware Haven did a video about chromeboxes running linux and their idle power draw was pretty impressive (being x86 they were sitting at 2-3w i believe)

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.

If you have a NUT server configured then you can depending on UPS vendor. My APC can and that's how I pull it into HA.

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.

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.

That's the one thing I don't like about Truenas. It technically can spin down disks, but there's no way to force them. You can set the idle timer to 5 minutes, but then it constantly spins them back up again. Now I just power the entire system down with home assistant outside of the usage hours and I can power it up again with home assistant using wake on Lan.

A bit goofy, but it works for me

So, averaging about 193W last month, that seems alright. What kind of hardware are you running?

IKEA also have some Zigbee plugs, but they have some models with and without power measuring, so check before buying.

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.

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.

My microwave, I think?

Rack mount synology bad, tplink Omada switch, wireless access point, rack fans, and a rack mount nutanix server repurposed as proxmox, but it’s only drawing on the IPMI as I’ve powered it down and moved any services over to containers on the NAS.

~500 watts continuous.

That's only about 170w continuous over 24h. This time of year, on a good day I'll generate 90kwh from solar and use about 60kwh total.

40 watts normal up to 60 watts. That includes modem and router.
PC is fanless system.

I'm actually up at 1am because the two servers I brought online pushed my usage to around 1200W and it was too much for my UPS plus solar battery setup to keep up with. Also I just discovered that my power cable was too high a gauge and it melted to the extension cord, so I had to pry it apart with a screwdriver. Oops.

At full tilt I pull around 2500 watts, but I haven't been fully up and running in months because I haven't had enough available circuits in my panel. Just upgraded my home service to 400a so I should be able to run some new outlets this weekend.

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.

Around 5kWh/day.

My Biggest Power drain is my homeserver/hypervisor/nas/whatever (5600G, 64gb ram, 9xHDD) which uses around 3.5kWh.
Wifi is provided by 2x Extreme Networks WS-AP3825i and 2x Ubiquiti UniFi 6 Plus which total to around 660W/h.
My Router is a small dual-nic shuttle pc with a Pentium G4560 drawing like 310W/h
Switching is done by an Aruba 2930F-24G-4SFP+ Switch that consumes 490W/h

I could probably squeeze out a few more watts if I replace the HDD's with higher density ones and virtualise my router but I really dont feel like doing that right now..

Its per hour. Basically my nas draws on average 40 W at any given moment. And it's nas but also run apps.

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.

What's using all this power? I have PhotoPrism, *arr stack, MeTube, nginx, Jellyfin, Syncthing, Vaulvarden, mongoDB and couple of smaller things and it's all running on a single laptop with a tiny RAID. It is all this data storage? I have <10TB so this looks like the biggest difference.

Averages 50-70 watts. Includes my main NUC NAS thing and all of my networking equipment.
