How we calculate consumption
We apply the average load factor to the entered power, multiply by hours and days, then convert the result into kWh and euros.
W ÷ 1000 × hours × load × days × €/kWh
The PSU rating is not real consumption
A 750 W power supply can support high peaks, but the computer usually draws much less. For better accuracy, use a plug-in power meter.
Workload matters
A dedicated GPU under a demanding game can dominate power use. At idle, during browsing or video playback, demand is usually much lower.
