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

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.
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.
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 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.
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
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”
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
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?
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.
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.
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.
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…
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?
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
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.
Yep. And they are talking about a couple more price hikes next year. Significant ones.
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.
Holy shit. I’m paying less than 10c per kwh even in the “high usage” tier.
I wish that was ours…
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 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.
Wow, that sounds like I have rookie numbers
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
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.
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.

I was drawing an average of 2.5kWh after a week of monitoring my whole rack
That doesn’t seem right; that’s only ~18W. Each one of those systems alone will exceed that at idle running 24/7. I’d expect 1-2 orders of magnitude more.
deleted by creator
after a week of runtime it told me 2.5kwh average. could be average per hour
If it gives you kWh as a measure for power, you should toss it because it’s obviously made by someone who had no idea what they were doing.
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.
