How much electricity does a Monero mining farm use?
A Monero mining farm can use a few kilowatts for a small group of computers or hundreds of kilowatts for a large setup. Your actual electricity use depends on the number of machines, their power draw while mining, and the cooling and other equipment keeping them running—not just the processors.
Start with power measured at the wall
Monero uses RandomX, a mining method designed to favor CPUs—the main processors in your computers. That makes a Monero farm’s electricity use different from a Bitcoin farm built around specialized mining machines.
For a useful estimate, measure each complete computer at the wall while it is mining steadily. A processor’s advertised power rating is not the whole computer’s electricity use.
Your wall measurement includes:
- The processor doing the mining.
- Memory, storage, motherboard, and fans.
- Energy lost when the power supply converts electricity for the computer.
A plug-in electricity meter can measure an individual machine. For larger installations, you may need metered power distribution equipment or an electrician’s help. Stay within the meter’s rated capacity.
Calculate the farm’s daily consumption
Two units matter:
- Kilowatts (kW) measure how much electrical power you are using at a given moment.
- Kilowatt-hours (kWh) measure how much electricity you use over time. This is usually what your electricity supplier bills you for.
Use this calculation:
Daily electricity use = total power in kW × hours running each day
For example, suppose you have 100 computers, each measured at 200 watts while mining:
- Computers: 100 × 200 watts = 20 kW.
- Fans, networking, and other supporting equipment: an assumed 2 kW.
- Total continuous demand: 22 kW.
- Daily consumption: 22 × 24 = 528 kWh.
- Consumption over 30 days: 15,840 kWh.
These are example assumptions, not standard Monero mining figures. Your machines could draw substantially more or less.
At an example electricity rate of $0.10 per kWh, that setup would cost $52.80 per day in electricity, before any extra utility charges.
Include cooling and electrical limits
Nearly all the electricity your mining computers consume eventually becomes heat. A room containing 20 kW of mining computers therefore needs to deal with roughly 20 kW of continuous heat.
Your cooling electricity depends on your climate and building:
- Outdoor-air ventilation may need mainly fan power.
- Air conditioning adds compressor power and can substantially increase consumption.
- Hot weather, blocked filters, and poor airflow can raise cooling demand.
Do not assume cooling always adds a fixed percentage. Measure it where possible, including seasonal changes.
A large farm also needs suitable wiring, circuits, and electrical service. Ask a qualified electrician to assess continuous loads rather than simply filling every available socket.
Compare efficiency, not just machine count
Two farms with the same number of computers can use very different amounts of electricity.
Compare hashes per second per watt: mining calculations completed each second for each watt consumed. Measure whole-system power consistently when making comparisons.
Efficient processors, sensible power limits, and carefully tested settings can reduce consumption. Browser mining also needs measurement; lower mining speed does not automatically mean better efficiency.
The bottom line
Estimate your farm’s electricity use from measured computer power, add cooling and supporting equipment, then multiply by operating hours. For the most reliable answer, monitor total site consumption over several days rather than relying on processor specifications alone.
