Cost to run a Dell PowerEdge R620 (1U server)
A Dell PowerEdge R620 (1U server) (Rack server) draws roughly 90 W at idle and up to 200 W under load. Run 24/7 at a typical ~123 W and the US average of $0.17/kWh, it uses about 1,077 kWh a year and costs roughly $183.17/year ($15.26/month). In higher-priced regions such as Germany (€0.40/kWh) the same device costs about €430.99/year. Adjust the calculator for your own draw and electricity price.

Idle vs load running cost
| Scenario | Power | Energy / year | Cost / year (US) |
|---|---|---|---|
| Idle | 90 W | 788 kWh | $134.03 |
| Typical 24/7 | 123 W | 1,077 kWh | $183.17 |
| Full load | 200 W | 1,752 kWh | $297.84 |
Idle depends on CPU count and PSU efficiency. Dual high-TDP CPUs raise both figures. Source: HomelabWatts wattage database, data as of 2026-06-13.
