To calculate the electricity consumption of your gaming PC, you'll need to know its average power draw in watts and how many hours you use it per day. Here's the formula:
Energy Consumption (kWh) = (Power Consumption (Watts) / 1000) * Hours of Use
For example, if your gaming PC uses 400 watts and you play for 4 hours a day:
Energy Consumption (kWh) = (400 / 1000) * 4 = 1.6 kWh per day
To calculate the monthly consumption, multiply the daily consumption by the number of days in a month.
The cost per hour of running your gaming PC depends on your local electricity rate. The average electricity cost in the US is around 13 cents per kWh, according to PC Gamer. Using this average rate, we can calculate the hourly cost for different PC builds:
PC Build
Load Wattage
Cost Per Hour (approx.)
Budget Build
310 W
4.03 cents
Mid-Range Build
388 W
5.04 cents
High-End Build
505 W
6.56 cents
Extreme Build
812 W
10.56 cents
As you can see, the cost per hour increases with the power of your PC. A high-end gaming rig can cost significantly more to run than a budget system.
The more you use your gaming PC, the higher your electricity bill will be. For example, if you game for 2 hours a day, a budget build might cost you around $29 a year, while an extreme build could cost about $77 a year, as noted by PC Gamer. Gamers who spend many hours daily on their PCs will see a more substantial increase in their electricity bills.
Electricity rates vary significantly by region. For example, the average electricity rate in California is around 22 cents per kWh, while in states like Washington, it can be as low as 10 cents per kWh, according to EnergySage. This means that the same gaming PC can cost different amounts to run depending on where you live. For example, running a 300-watt gaming PC for 5 hours a day in New York could cost around $10.35 per month, while the same usage in Florida might cost around $7.20 per month, as reported by The Energy Professor.
Outdated components often consume more power to achieve the same level of performance as newer, more efficient parts. Upgrading to newer components can improve performance and reduce power consumption. For instance, older graphics cards and CPUs tend to be less energy-efficient than their modern counterparts.
The type of software and games you run significantly impacts power usage. Demanding games with high graphical settings will push your CPU and GPU to their limits, increasing power consumption. Less graphically intensive games or applications will use less power.
Dust buildup inside your PC can lead to overheating, forcing components to work harder and consume more power. Regular cleaning of your PC's interior can help maintain optimal performance and reduce power consumption. According to The Energy Professor, dust accumulation can cause your PC to overheat, making it use more power.
