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 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 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.
I’d say no more than 15W.
1x Jetson Nano
1x SSD
3x 2.5" HDDs
1x RPi 3B wih Pihole7 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.
Nice
What hardware are you running?
11th gen i3 NUC, headless Debian.
Like 3-12w but I’m only running a little mostly jellyfin server
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
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.
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: 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.
1,514.75AUD per year
What apps are you running?
My budget is under 100w for 3 servers with a combined 18tb of ssd and 28tb of spinning rust that stays spun down unless I need to so a cold backup.
3 Lenovo Tiny’s, one HP Mini, 3 external drives, a switch and 2 modems runs just under 100W.
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.
If I fire up everything in the rack it’s several kilowatts. Probably more than a 230 V wall socket can handle.
Usually it’s way less, though right now it’s just a switch and the router/firewall, mere 57 W.
I make most of my own net power with solar PV, soon 4 kWp in total.
Around 400W, including switches and access points.
