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

45 to 55 watt.

But I make use of it for backup and firewall. No cloud shit.

Mine runs at about 120 watts per hour.

Please. Watt is an SI unit of power, equivalent of Joule per second. Watt-hour is a non-SI unit of energy( 1Wh = 3600 J). Learn the difference and use it correctly.

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] 4 points 1 month ago* (last edited 1 month ago) (1 children)

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 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?

[–] [email protected] 2 points 1 month ago

If 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.

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.

[–] [email protected] 3 points 1 month ago

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

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 😀

[–] [email protected] 4 points 1 month ago

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.

[–] [email protected] 2 points 1 month ago

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"

[–] [email protected] 4 points 1 month 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] 3 points 1 month 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

[–] [email protected] 2 points 1 month 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
