Energy Efficiency of Mini PCs: Calculate Your Long-Term Cost Savings
Mini PCs aren't just space-savers - they're significant energy savers too. Understanding their power efficiency can help you make informed decisions about long-term costs and environmental impact. This guide will help you calculate potential savings and optimize your mini PC's energy consumption.
Power Consumption Comparison
Traditional Desktop vs. Mini PC Power Usage
Average power consumption rates:
- Traditional Desktop: 200-400W under load, 50-70W idle
- Gaming Desktop: 400-800W under load, 70-100W idle
- Mini PC: 10-65W under load, 5-10W idle
- Mini PC with eGPU: 150-300W under load, 15-25W idle
Calculate Your Savings
Annual Energy Cost Formula
Use this formula to calculate annual energy costs:
Annual Cost = (Daily Usage Hours × Power Consumption × Electricity Rate × 365) ÷ 1000
Where:
- Daily Usage Hours = Time computer is on per day
- Power Consumption = Average watts used
- Electricity Rate = Cost per kilowatt-hour (kWh)
- Result is in your local currency
Sample Calculations
Based on $0.15/kWh and 8 hours daily use:
- Traditional Desktop (250W): $109.50 annually
- Gaming Desktop (500W): $219.00 annually
- Mini PC (35W): $15.33 annually
- Potential annual savings: $94.17 - $203.67
