I’ll just come out and say it: 50W. I know, I know an order of magnitude above what’s actually needed to host websites, media center and image gallery.
But it is a computer I had on-hand and which would be turned on a quarter of the day anyway. And these 50W also warm my home, although this is less efficient than the heat pump, of course.
What’s your usage? What do you host?

Good timing for this thread. I just finished consolidating 2 computers worth of fun into 1 newer computer that can do it all. I sold my wife on the idea with electricity as the reasoning.
In the end, it uses 30 watts less, which is not as much as I had hoped. That’s about $5 a month.
180 watts with an i5-13400, 9 spinning disks, 1 M.2 SSD, no extra GPU, 24 port switch (powers 3 AP’s), modem, Mikrotik router, and a large UPS. I wonder if the UPS uses any power as a trickle charge for the batteries.
What are your electricity prices that 30w costs €5/m
30w x 24 hr./day *30 days/mo. = 21.6 kWh. I pay about $.25/kWh, so $5.40.
Spain would probably be around that much if my calculations are correct.
0.12kWh but I’m also running 6 HDDs in raid10 so the spin down time is not optimal.
That’s energy, not power. If that’s the energy consumption per hour, then that’s 120W, which is high but not outrageous with a full size computer with 6 disks.
Correct. I assumed a normalized kWh rating would be better than any instantaneous measurement I had on hand.
Mine is around 10W average.
It runs:
- Websites
- my blog
- Jellyfin
- Home assistant
- Nextcloud
And a few other things.
Probably about a kilowatt.
50 watts is maybe halfof one of my 10 gig switches…
~120W with an old server motherboard and 6 spinning drives (42TB of storage overall).
Currently running Nextcloud, Home Assistant, Gitea, Matrix, Jellyfin, Lemmy, Mastodon, Vaultwarden, and a bunch of other smaller stuff alongside storing a few months worth of surveillance footage, so ~$12/month in power certainly ain’t a bad deal versus paying for hosted versions of even a fraction of those services.
I have looked at the ROI for getting more efficient kit and ended up discovering that going for something like a low-idle-power-draw system like a NUC or thin client and a disk enclosure has a return period on the order of multiple years.
Based on that information, I’ve instead put that money towards lower hanging fruit in the form of upgrading older inefficient appliances and adding multi-zone temperature control for power savings.
The energy savings I’ve been able to make based on long-term energy use data collected via Home Assistant has more than offset all of the electricity I’ve ever used to power the system itself.
Depends where you draw the line of the home lab. I’m drawing 160W at the moment, but that includes a dedicated CCTV PC (running Proxmox in a cluster) and POE switch. The CCTV I don’t consider part of the home lab really, the alternative would be an off the shelf box and no one would consider that.
The 160W also includes a 24 port switch (I’m only using 8) and the FTTP power, plus the rake from the UPS. So probably total the actual homelab server would be about 80-100, I guess. But even then it runs my router using opnsense, so I don’t have a separate router box to power. It also serves as my “cloud” storage, so I’m not saving watts, but I’m saving the cost there.
I could get the power down quite a bit by changing the 6 HDD for 2 mirrored HDD, but the cost of large enough disks means it’d be years before it paid for itself, so I’m sticking with 6 small disks for now.
I’ve thought about trimming things down and going lower powered, but it all comes back to storage and needing the large storage online all the time.
Plus I consider a 100W a big saving when before I ran a dual Xeon Dell R710 which used around 225W under the same workload.
I really don’t know much it’s actually using but my NAS has a 550W power adapter …
So you know - that’s the max power output rating of the power supply. The NAS can be using anything “up to” that amount. Likely well below it.
Yeah, that’s how power adapters usually work. Thanks.
Sorry - I thought you didn’t know rather than were just offering completely useless information on purpose.
Well, I don’t know how much it’s using but I suspected it was somewhere between 0 and 550 ;)
Thank you for your valuable contribution.
I recommend buying one of these things for finding this out: https://ae01.alicdn.com/kf/HTB1sJx0lrZnBKNjSZFGq6zt3FXao/EU-Plug-Digital-Voltage-Wattmeter-Power-Meter-Consumption-Watt-Energy-KWh-Socket-220V-230V-AC-Electricity.jpg
I use an Intel SBC with 10W TDP CPU in it. With a HDD and after PSU inefficiency, it draws about 10-20W depending on the load.
That’s impressive.
What do you use the system for? And services like PiHole or media server?
That’s impressive.
Yeah, you really don’t need a lot of CPU power for selfhosting.
It’s a J4105, forgot to mention that.
What do you use the system for? And services like PiHole or media server?
Oh, sorry, forgot to add that bit.
It’s mainly a NAS housing my git-annex repos that I access via SSH.
I also host a few HTTP services on it:
The services I use most here are Paperless and Piped.
Mealie will be added to that list as soon as the upstream PR lands which might be later this evening.
My Immich module is almost ready to go but the Immich app has a major bug preventing me from using it properly, so that’s on hold for now.
I do want to set up Jellyfin in the not too distant future. The machine should handle that just fine with its iGPU as Intel’s Quicksync is quite good and I probably won’t even need transcoding for most cases either.
I probably won’t be able to get around setting up Nextcloud for much longer. I haven’t looked into it much but I already know it’s a beast. What I primarily want from it is calendar and contact synchronisation but I’d also like to have the ability to share files or documents with mere mortals such as my SO or family.
The NixOS module hopefully abstracts away most of the complexity here but still…Makes sense that basic file hosting shouldn’t use much power.
Sharing stuff with friends and family is in my plan, eventually, not sure what approach to take yet, but I’d like to avoid an app for them, if I can (people are resistant to apps, I kind of get it).
I’ve looked at Nextcloud/Owncloud a few times, and it always seems like a lot more than I need, though I also want to move my calendar, contacts, etc, to my own hosting. Not sure what the right answer is, lol.
My setup already goes quite a bit beyond basic file hosting.
There is no self hosted service I could imagine to need that I’d expect not to be able to host due to CPU constraints. I think I’ll run into RAM constraints first; it’s already at 3GiB after boot.
AMD Ryzen 5600G
B550 Aorus Master
2x16 Ripjaw V 3200mhz

1x 6TB Seagate Ironwolf for backup important data
1x 500GB Samsung evo 970 as systemdrive
1x 500GB Crucial P1 as cache and download
1x 2TB Crucial P3 for docker, apps, databases, incus
Bequiet 400W
Nvidia GTX 1660 Super
Idle power 53w, totally worth it ☺️ The extra graphic card is for Immich and Ollama / overall transcoding.
I currently have probably 10% of your performance at 2x the power draw. 😭
😳😳😳
Get new hardware or you will pay it with your energy bill
Lol, I’ve been paying for years! (It’s been about $1/day).
I’m working on it. Have a new NAS box I’m currently setting up - it’s max output power is 180w, I should know later today what my idle power is like.
And then… I get to restructure all our data stores, backup processes, etc. Oh fun.
No idea!
Going from publicly-available info though:
Rpi4B - 6.4W max (more like 5 in real world usage)
Cpu case fan - 1.4W
2x SSD - ~6W each
13.8 to ~18 depending on what the SSDs are pulling i guess. I use it as an *arr seedbox and plex server (up to 1080p h264 works flawlessly!) as well as nextcloud
~600W. 2 machines: Dell 730 8 disks running multiple Minecraft servers. Supermicro 16 disks in raid 10 running multiple VM for various functions. All on a 6kva ups (overkill I know)
Luckily I have a large solar array.
~25W which consists of:
- Mini PC
- Lenovo Thinkcentre M700 Tiny
- i5-6500T
- 8GB DDR4
- 500GB SSD
- External USB 3.5" enclosure
- 2 x 2 TB HDD
- Network switch
- 4 Ports Gigabit
I’ve been thinking about upgrading because the CPU isn’t that fast, the RAM ain’t that much and I want to add a few more HDD’s. I’ve seen a pretty interesting Lenovo P520 with 64GB RAM a CPU that’s 3x times as fast and room for 6 HDD’s for €350, but the power consumption I can see online (80W) isn’t that appealing with European electricity prices.
- Mini PC
