how much power does your system need?

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.

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.

0.1kWh per hour? Day? Month?

What's in your system?

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...

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.

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

Idle: 30 Watts

Starting all docker containers after reboot: 140 Watts

It needs around 28 kWh per month.

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

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

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 😭

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.

the boxes i have running 24/7 use about 20w max each, and about half that at idle or 'normal' loads.

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.

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

45 to 55 watt.

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

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

Mine runs at about 120 watts per hour.

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.

80-110W

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

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).

AiBot post. Fuck this shit.

80-100 watts at idle which is most of the time. Two OS drives, two fast drives, two spinners, lots of networking and always syncing with the rest of the cluster.

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

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

For two servers (one with a lot of spinning rust), two switches, and a few other miscellaneous network appliances. My server rack averages around 600-650W. During periods of high demand (nightly backups, for instance), that can peak at around 750W.

My servers (an old desktop overstuffed with drives and an old dell laptop), networking gear and a 50 gal aquarium all run on the same outlet. As long as the aquarium heater is off, the outlet pulls about 200 watts. The aquarium heater spikes that to 400 watts when it kicks in.

There are some really efficient systems out there, but power requirements depend a lot on what is run.

A simple website is very different that a photo gallery running content ID for example.
