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

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?

[–] [email protected] 2 points 3 hours ago

My server uses about 6-7 kWh a day, but its a dual CPU Xeon running quite a few dockers. Probably the thing that keeps it busiest is being a file server for our family and a Plex server for my extended family (So a lot of the CPU usage is likely transcodes).

Is there a (Linux) command I can run to check my power consumption?

[–] bitwaba 1 points 1 hour ago

If you have a laptop/something that runs off a battery, upower

Or smart sockets. I got multiple of them (ZigBee ones), they are precise enough for most uses.

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

[–] [email protected] 7 points 9 hours ago (2 children)

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 😀

[–] bitwaba 2 points 1 hour ago

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.

[–] [email protected] 2 points 6 hours ago

we're in the same boat, but it does the job and stays under 45°C even under load, so I'm not complaining

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.

[–] [email protected] 2 points 11 hours ago

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.

Pulling around 200W on average.

  • 100W for the server. Xeon E3-1231v3 with 8 spinning disks + HBA, couple of sata SSD’s
  • ~80W for the unifi PoE 48 Pro switch. Most of this is PoE power for half a dozen cameras, downstream switches and AP’s, and a couple of raspberry pi’s
  • ~20W for protectli vault running Opnsense
  • Total usage measured via Eaton UPS
  • Subsidised during the day with solar power (Enphase)
  • Tracked in home assistant
[–] [email protected] 5 points 18 hours ago (1 children)

For the whole month of November. 60kWh. This is for all my servers and network equipment. On average, it draws around 90 watt.

[–] [email protected] 2 points 14 hours ago (2 children)

How you measuring this? Looks very neat.

[–] [email protected] 3 points 7 hours ago

Shelly plug, integrated into Home Assistant.

[–] thumdinger 2 points 12 hours ago

Looks like home assistant

kWh is a unit of energy, not power

[–] Valmond 2 points 17 hours ago* (last edited 17 hours ago) (1 children)

Wasn't it stated for the usage during November? 60kWh for november. Seems logic to me.

Edit: forget it, he's saying his server needs 0.1kWh which is bonkers ofc

[–] [email protected] 4 points 17 hours ago (1 children)

Only one person here has posted its usage for November. The OP has not talked about November or any timeframe.

[–] Valmond 1 points 7 hours ago

Yeah misxed up pists, thought one depended on another because it was under it. Again forget my post :-)

Idles at around 24W. It’s amazing that your server only needs .1kWh once and keeps on working. You should get some physicists to take a look at it, you might just have found perpetual motion.

My home rack draws around 3.5kW steady-state, but it also has more than 200 spinning disks

[–] [email protected] 1 points 37 minutes ago

I think I would go over 10 kW if I fire up everything. Only obout 80 spinny plates of rust though.
