Electricity Costs
The table shows the annual electricity cost with each machine headless running at idle. This information may be useful if you are thinking of using the machine say as a NAS server and want a baseline running cost. I’m pricing a kWh at £0.2573 (the current price cap from July 2025 in the UK).
| Computer | Wh | Cost |
|---|---|---|
| Orange Pi 5 Max | 2.4 | £5.41 |
| Orange Pi RV2 | 2.5 | £5.63 |
| Orange Pi R2S | 2.8 | £6.31 |
| Raspberry Pi 5 | 3.5 | £7.89 |
| DreamQuest N100 CPU | 6.5 | £14.65 |
| DreamQuest N95 CPU | 7.8 | £17.58 |
| Mini PC Intel NUC 13 Pro i7-1360P CPU | 12.7 | £28.63 |
