DCiE & PUE Comparison Calculator

Calculate PUE and DCiE from detailed power breakdown. Get benchmark rating and see overhead contributions.

Total power consumed by IT equipment: servers, storage, networking.
kW
Total power for cooling: CRACs, chillers, cooling towers, pumps, fans. Typically 30-40% of total.
kW
Power for facility lighting including data hall, offices, exterior.
kW
Power lost in UPS conversion, PDUs, transformers, switchgear. Typically 5-15% of IT load.
kW
Security, fire suppression, BMS, humidification, office equipment.
kW

Total Facility Power:
Sum of all power components.
-kW
PUE (Power Usage Effectiveness):
PUE = Total / IT. Ideal 1.0. Best-in-class 1.1-1.2. Average 1.5-1.6.
-
DCiE (DC infrastructure Efficiency):
DCiE = (IT / Total) x 100%. Reciprocal of PUE as percentage. Higher is better.
