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.

kWh is a unit of energy, not power

Do you mean 0.1kWh per hour, so 0.1kW or 100W?

My N100 server needs about 11W.

0.1kWh per hour? Day? Month?

What's in your system?

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.

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 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 😀

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

9 spinning disks and a couple SSD's - Right around 190 watts, but that also includes my router and 3 PoE WiFi AP's. PoE consumption is reported as 20 watts, and the router should use about 10 watts, so I think the server is about 160 watts.

Electricity here is pretty expensive, about $.33 per kWh, so by my math I'm spending $38/month on this stuff. If I didn't have lots of digital media it'd be worth it to get a VPS probably. $38/month is still cheaper than Netflix, HBO, and all the other junk I'd have to subscribe to.

17W for an N100 system with 4 HDD's

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.

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...

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

About 700 watts, it makes for a decent space heater in the winter.

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.

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.

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 😭

Idle: 30 Watts

Starting all docker containers after reboot: 140 Watts

It needs around 28 kWh per month.

My server with 8 hard drives uses about 60 watts and goes up to around 80 under heavy load. The firewall, switch, access points and modem use another 50-60 watts.

I really need upgrade my server and firewall to something about 10 years newer, it would reduce my power consumption quite a bit and I would have a lot more runtime on UPS.

I'm idling at 120W with eight drives, but I'm currently looking into how to lower it.
