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 😀

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 mths 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

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.

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

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

kWh is a unit of energy, not power

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.

I use unraid with 5950x and it wouldn't stop crashing until I disabled c states

So that plus 18 hdds and 2 ssds it sits at 200watts 24/7

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

Running an old 7th gen Intel, It has a 2070 and a 1080 in it, six mechanical hard drives 3 SSDs. Then I have an eighth gen laptop with a 1070 TI mobile. But the laptop's a camera server so it's always running balls to the wall. Running a unified dream machine pro, 24 port poe, 16 port poe and an 8 port poe

Because of the overall workload and the age of the CPU, it burns about 360 watts continuous.

I can save a few watts by putting the discs to sleep, But I'm in the camp where the spin up and spin down of the discs cost more wear than continuous running.

Edit: cleaned up the slaughter from the dictation, after I cleaned up my physical space from Christmas festivities.

17W for an N100 system with 4 HDD's

Around 18-20 Watts on idle. It can go up to about 40 W at 100% load.

I have a Intel N100, I'm really happy about performance per watt, to be honest.

0.1kWh per hour? Day? Month?

What's in your system?

You might have your units confused.

0.1kWh over how much time? Per day? Per hour? Per week?

Watthours refer to total power used to do something, from a starting point to an ending point. It makes no sense to say that a device needs a certain amount of Wh, unless you're talking about something like charging a battery to full.

Power being used by a device, (like a computer) is just watts.

Think of the difference between speed and distance. Watts is how fast power is being used, watt-hours is how much has been used, or will be used.

If you have a 500 watt PC, for example, it uses 500Wh, per hour. Or 12kWh in a day.

50W-ish idle? Ryzen 1700, 2 HDDs, and a GTX 750ti. My next upgrade will hopefully cut this in half.
