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

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.
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 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 😀
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’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.
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”
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
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.
Idle: 30 Watts Starting all docker containers after reboot: 140 Watts
It needs around 28 kWh per month.
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.
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 😭
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.
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
AiBot post. Fuck this shit.
Can you please explain?
50W-ish idle? Ryzen 1700, 2 HDDs, and a GTX 750ti. My next upgrade will hopefully cut this in half.
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.
Looks like home assistant
Shelly plug, integrated into Home Assistant.
0.1kWh per hour? Day? Month?
What’s in your system?
Computer with gpu and 50TB drives. I will measure the computer on its own in the enxt couple of days to see where the power consumption comes from
Which GPU? How many drives?
Put a kill-o-watt meter on it and see what it says for consumption.
You are misunderstanding the confusion, Kwh is an absolute measurement of an amount of power, not a rate of power usage. It’s like being asked how fast your car can go and answering it can go 500 miles. 500 miles per hour? Per day? Per tank? It doesn’t make sense as an answer.
Does your computer use 100 watt hours per hour? Translating to an average of 100 watts power usage? Or 100 watt hours per day maybe meaning an average power use of about 4 watts? One of those is certainly more likely but both are possible depending on your application and load.
Yeah but tbh it’s understandable that OP got confused. I think he just means 100W
He might, but he also might mean that he has a power meter that is displaying Kwh since last reset and he plugged it in and then checked it again later when it was all set up after an arbitrary time period and it was either showing the lowest non-zero value it was capable of displaying or was showing a number from several hours.
You’re adding to the confusion.
kWh (as in kW*h) and not kW/h is for measurement of energy.
Watt is for measurement of power.They said kilawatt hours per how, not kilawatts per hour.
kWh/h = kW
The h can be cancelled, resulting in kW. They’re technically right, but kWh/h shouldn’t ever be used haha.
Lol thank you, I knew that I don’t know why I wrote it that way, in my defense it was like 4 in the morning.
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.
That’s true. And the children of my family see no ads which is priceless. Yet I am looking into ways to cut costs in half by using an additional lower powered mini pc which is always on and the main computer only running in the evening - maybe.
Same here. 300w with 12 disks, switches, and router. But electricity only costs $.12/kwh. I wouldn’t trust having terabytes of data in the cloud.
