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.
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 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.
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.
