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

50W-ish idle? Ryzen 1700, 2 HDDs, and a GTX 750ti. My next upgrade will hopefully cut this in half.
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.
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
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.
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.
.1kWh is 100Wh
This is a factual but irrelevant statement
I ate sushi today.
Good point. Now it does make sense. I know the secret to the perpetual motion machine now.
For the whole month of November. 60kWh. This is for all my servers and network equipment. On average, it draws around 90 watt.
How you measuring this? Looks very neat.
Shelly plug, integrated into Home Assistant.
Looks like home assistant
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
17W for an N100 system with 4 HDD’s
Which HDDs? That’s really good.
Seagate Ironwolf “ST4000VN006”
I do have some issues with read speeds but that’s probably networking related or due to using RAID5.
That’s pretty low with 4 HDD’s. One of my servers use 30 watts. Half of that is from the 2 HDD’s in it.
@meldrik @qaz I’ve got a bunch of older, smaller drives, and as they fail I’m slowly transitioning to much more efficient (and larger) HGST helium drives. I don’t have measurements, but anecdotally a dual-drive USB dock with crappy 1.5A power adapter (so 18W) couldn’t handle spinning up two older drives but could handle two HGST drives.
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 😭
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.
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…
Holy shit. I’m paying less than 10c per kwh even in the “high usage” tier.
I wish that was ours…
that’s insane, i pay like 5¢ a KWh
Want to switch?
That seems really high, I think power where I live is about 12-14 cents per kilowatt hour. What makes it so expenses where you live?
0.50 $/kWh is a normal price in Europe now
Damn, I wish ours was that cheap. We’re roughly $.30/kwh, mostly because our local poco is a reseller of SCE and we’re in a rural area.
Mostly just that they can. It’s more expensive per tier actually.

Take a look, this is the old pricing. They just voted to up it again.
There’s legislation that is moving along to charge people with solar because…idk.
They’re charging for solar because PGE is a greedy fuck.
Yes. There was talk locally for local government to take control of the power but it’s just talk…
It gets over 110 where I live in the summer…so air conditioning can make it very expensive.
Wait this is in the US? How, this is even more expensive than Hawaii, and they have obvious reasons for power to be more expensive there
Yep. And they are talking about a couple more price hikes next year. Significant ones.
PGE serves Northern California. They keep raising rates like 10-15% each year to cover their losses after all the wildfires a couple years ago and because of the greed.
Take note, folks. Watch this trend spread.
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 😀
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.
we’re in the same boat, but it does the job and stays under 45°C even under load, so I’m not complaining
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.
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”
kWh is a unit of energy, not power
I was really confused by that and that the decided units weren’t just in W (0.1 kW is pretty weird even)
Wh shouldn’t even exist tbh, we should use Joules, less confusing
Watt hours makes sense to me. A watt hour is just a watt draw that runs for an hour, it’s right in the name.
Maybe you’ve just whooooshed me or something, I’ve never looked into Joules or why they’re better/worse.
Joules (J) are the official unit of energy. 1W=1J/s. That means 1Wh=3600J or that 1J is kinda like “1 Watt second”. You’re right that Wh is easier since everything is rated in Watts and it would be insane to measure energy consumption by seconds. Imagine getting your electric bill and it says you’ve used 3,157,200,000J.
3,157,200,000J
Or just 3.1572GJ.
Which apparently is how this Canadian natural gas company bills its customers: https://www.fortisbc.com/about-us/facilities-operations-and-energy-information/how-gas-is-measured
I guess it wouldn’t make sense to measure energy used by gas-powered appliances in Wh since they’re not rated in Watts. Still, measuring volume and then converting to energy seems unnecessarily complicated.
Thanks for the explainer, that makes a lot of sense.
At least in the US, the electric company charges in kWh, computer parts are advertised in terms of watts, and batteries tend to be in amp hours, which is easy to convert to watt hours.
Joules just overcomplicates things.

Wow, the US education system must be improved.
I pay my electric bill by the kWh too, and I don’t live in the US. When it comes to household and EV energy consumption, kWh is the unit of choice.
1J is 3600Wh.
No, if you’re going to lecture people on this, at least be right about facts. 1W is 1J/s. So multiply by an hour and you get 1Wh = 3600J
That’s literraly the same thing,
It’s not literally the same thing. The two units are linearly proportional to each other, but they’re not the same. If they were the same, then this discussion would be rather silly.
but the name is less confusing because people tend to confuse W and Wh
Finally, something I can agree with. But that’s only because physics is so undervalued in most educational systems.
I did a physics degree and am comfortable with Joules, but in the context of electricity bills, kWh makes more sense.
All appliances are advertised in terms of their Watt power draw, so estimating their daily impact on my bill is as simple as multiplying their kW draw by the number of hours in a day I expect to run the thing (multiplied by the cost per kWh by the utility company of course).
Do you regularly divide/multiply by 3600? That’s not something I typically do in my head, and there’s no reason to do it when everything is denominated in watts. What exactly is the benefit?
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
Only one person here has posted its usage for November. The OP has not talked about November or any timeframe.
Yeah misxed up pists, thought one depended on another because it was under it. Again forget my post :-)
AiBot post. Fuck this shit.
Can you please explain?
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
