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.

0.1kWh per hour? Day? Month?

What's in your system?

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

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

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

My N100 server needs about 11W.

17W for an N100 system with 4 HDD's

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

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.

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.

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

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.

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 😭

last I checked with a kill-a-watt I was drawing an average of 2.5kWh after a week of monitoring my whole rack. that was about three years ago and the following was running in my rack.

• r610 dual 1kw PSU
• homebuilt server Gigabyte 750w PSU
• homebuilt Asus gaming rig 650w PSU
• homebuilt Asus retro(xp) gaming/testing rig 350w PSU
• HP laptop as dev env/warmsite ~ 200w PSU
• Amcrest NVR 80w (I guess?)
• HP T610 65w PSU
• Terramaster F5-422 90w PSU
• TP-Link TL-SG2424P 180w PSU
• Brocade ICX6610-48P-E dual dual 1kw PSU
• Misc routers, rpis, poe aps, modems(cable & 5G) ~ 700w combined (cameras not included, brocade powers them directly)

I also have two battery systems split between high priority and low priority infrastructure.

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

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.

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