I wonder if my system is good or bad. My server needs 0.1kWh.

Mate, kWh is a measure of electricity volume, like gallons is to liquid. Also, 100 watt hours would be a much more sensical way to say the same thing. What you’ve said in the title is like saying your server uses 1 gallon of water. It’s meaningless without a unit of time. Watts is a measure of current flow (pun intended), similar to a measurement like gallons per minute.
For example, if your server uses 100 watts for an hour it has used 100 watt hours of electricity. If your server uses 100 watts for 100 hours it has used 10000 watts of electricity, aka 10kwh.
My NAS uses about 60 watts at idle, and near 100w when it’s working on something. I use an old laptop for a plex server, it probably uses like 50 watts at idle and like 150 or 200 when streaming a 4k movie, I haven’t checked tbh. I did just acquire a BEEFY network switch that’s going to use 120 watts 24/7 though, so that’ll hurt the pocket book for sure. Soon all of my servers should be in the same place, with that network switch, so I’ll know exactly how much power it’s using.
Between 50W (idle) and 140W (max load). Most of the time it is about 60W.
So about 1.5kWh per day, or 45kWh per month. I pay 0,22€ per kWh (France, 100% renewable energy) so about 9-10€ per month.
Are you including nuclear power in renewable or is that a particular provider who claims net 100% renewable?
Net 100% renewable, no nuclear. I can even choose where it comes from (in my case, a wind farm in northwest France). Of course, not all of my electricity come from there at all time, but I have the guaranty that renewable energy bounds equivalent to my consumption will be bought from there, so it is basically the same.
Thanks. I buy Vattenfall but make net 2/3rds of my own power via rooftop solar.
My server rack has
- 3x Dell R730
- 1x Dell R720
- 2x Cisco Catalyst 3750x (IP Routing license)
- 2x Netgear M4300-12x12f
- 1x Unifi USW-48-Pro
- 1x USW-Agg
- 3x Framework 11th Gen (future cluster)
- 1x Protectli FE4B
All together that draws… 0.1 kWh… in 0.327s.
In real time terms, measured at the UPS, I have a running stable state load of 900-1100w depending on what I have at load. I call it my computationally efficient space heater because it generates more heat than is required for my apartment in winter except for the coldest of days. It has a dedicated 120v 15A circuit
17W for an N100 system with 4 HDD’s
I came here to tell my tiny Raspberry pi 4 consumes ~10 watt, But then after noticing the home server setup of some people and the associated power consumption, I feel like a child in a crowd of adults 😀
I’m using an old laptop with the lid closed. Uses 10w.
All in, including my router, switches, modem, laptop, and NAS, I’m using 50watts +/- 5.
It does everything I need, and I feel like that’s pretty efficient.
I have an old desktop downclocked that pulls ~100W that I’m using as a file server, but I’m working on moving most of my services over to an Intel NUC that pulls ~15W. Nothing wrong with being power efficient.
Quite the opposite. Look at what they need to get a fraction of what you do.
Or use the old quote, “they’re compensating for small pp”
I think at max 200w? It runs a collection of fedi/self service stuff.
I also run a pi with a couple of apps on a pi 3 that sips power.
It’s a legitimate issue because it’s 50+ cents per killowat hour where I live so power is very expensive…
Holy shit. I’m paying less than 10c per kwh even in the “high usage” tier.
I wish that was ours…
that’s insane, i pay like 5¢ a KWh
Want to switch?
My whole setup including 2 PIs and one fully speced out AM4 system with 100TB of drives a Intel Arc and 4x 32gb ecc ram uses between 280W - 420W I live in Germany and pay 25ct per KWh and my whole apartment uses 600w at any given time and approximately 15kwh per day 😭
My 10 year old ITX NAS build with 4 HDDs used 40W at idle. Just upgraded to an Aoostart WTR Pro with the same 4 HDDs, uses 28W at idle. My power bill currently averages around US$0.13/kWh.
Is there a (Linux) command I can run to check my power consumption?
Get a Kill-a-Watt meter.
Or smart sockets. I got multiple of them (ZigBee ones), they are precise enough for most uses.
If you have a laptop/something that runs off a battery,
upowerIf you have a server with out-of-band/lights-out management such as iDRAC (Dell), iLO (HPe), IPMI (generic, Supermicro, and others) or equivalent, those can measure the server’s power draw at both PSUs and total.
With everything on, 100W but I don’t have my NAS on all the time and in that case I pull only 13W since my server is a laptop
80-110W
last I checked with a kill-a-watt I was drawing an average of 2.5kWh after a week of monitoring my whole rack. that was about three years ago and the following was running in my rack.
- r610 dual 1kw PSU
- homebuilt server Gigabyte 750w PSU
- homebuilt Asus gaming rig 650w PSU
- homebuilt Asus retro(xp) gaming/testing rig 350w PSU
- HP laptop as dev env/warmsite ~ 200w PSU
- Amcrest NVR 80w (I guess?)
- HP T610 65w PSU
- Terramaster F5-422 90w PSU
- TP-Link TL-SG2424P 180w PSU
- Brocade ICX6610-48P-E dual dual 1kw PSU
- Misc routers, rpis, poe aps, modems(cable & 5G) ~ 700w combined (cameras not included, brocade powers them directly)
I also have two battery systems split between high priority and low priority infrastructure.

That doesn’t seem right; that’s only ~18W. Each one of those systems alone will exceed that at idle running 24/7. I’d expect 1-2 orders of magnitude more.
IDK, after a week of runtime it told me 2.5kwh average. could be average per hour?
Highest power bill I ever saw was summer of 2022. $1800. temps outside were into to 110-120 range and was the hottest ever here.
maybe I’ll hook it back up, but I’ve got different (newer) hardware now.

If it gives you kWh as a measure for power, you should toss it because it’s obviously made by someone who had no idea what they were doing.
The PC I’m using as a little NAS usually draws around 75 watt. My jellyfin and general home server draws about 50 watt while idle but can jump up to 150 watt. Most of the components are very old. I know I could get the power usage down significantly by using newer components, but not sure if the electricity use outweighs the cost of sending them to the landfill and creating demand for more newer components to be manufactured.
50W-ish idle? Ryzen 1700, 2 HDDs, and a GTX 750ti. My next upgrade will hopefully cut this in half.
the boxes i have running 24/7 use about 20w max each, and about half that at idle or ‘normal’ loads.
