How to Use This Calculator
  1. Enter the number of miners planned for the facility and the power draw per miner in watts.
  2. Set the floor space allocated per miner and the facility's Power Usage Effectiveness (PUE) target.
  3. Input the site's ambient temperature and the desired electrical redundancy level (N, N+1, or 2N).
  4. Review the total IT and facility power draw, cooling power, and total facility size.
  5. Use the cooling tons, heat output, required airflow, and electrical panel count to plan infrastructure and rack layout.

What each input means

Number of miners
Total mining units planned for the facility.
Power per miner (W)
Wall power draw of each mining unit in watts.
Floor space per miner (sq ft)
Floor space allocated per miner including aisle access. Typical: 6-10 sq ft.
Power Usage Effectiveness (PUE)
Ratio of total facility power to IT power. 1.0 = perfect, 1.2 = efficient immersion cooling, 1.5 = typical air-cooled.
Ambient temperature (°F)
Average outdoor temperature at the facility location. Affects cooling sizing.
Electrical redundancy (N+?)
Transformer redundancy: 1 = N (no redundancy), 2 = N+1 (one backup), 3 = 2N (full redundancy).

What each result means

Total IT power (kW)
Combined power draw of all mining equipment.
Total facility power (kW)
Total power including cooling and infrastructure overhead (IT × PUE).
Cooling power (kW)
Power dedicated to cooling systems.
Transformer capacity (kVA)
Required transformer sizing with selected redundancy level.
Total facility size (sq ft)
Estimated total facility footprint including miners, electrical room, and cooling.
Cooling required (tons)
Total cooling capacity needed in refrigeration tons, adjusted for ambient temperature.
Heat output (BTU/hr)
Total heat generated by mining equipment that must be removed.
Airflow required (CFM)
Cubic feet per minute of airflow needed for air-cooled setups.
Electrical panels needed
Number of 200A/480V distribution panels required.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Number of miners = 100, Power per miner (W) = 3250, Floor space per miner (sq ft) = 8, Power Usage Effectiveness (PUE) = 1.25 = 6 input(s) provided
  2. Calculate Total IT power
    Total IT power = (numMiners * powerPerMiner) / 1000
    325 = 325
  3. Calculate Total facility power
    Total facility power = totalItPowerKw * pue
    406.25 = 406.25
  4. Calculate Cooling power
    Cooling power = totalFacilityPowerKw - totalItPowerKw
    81.25 = 81.25
  5. Calculate Transformer capacity
    Transformer capacity = transformerKva * redundancyLevel
    451 = 451
