The power consumption of a gaming PC varies depending on its components and usage. Typically, a gaming PC uses between 300 and 800 watts while playing games, with high-end systems sometimes exceeding 1000 watts. For a typical gaming session lasting 4 to 6 hours, this can result in around 1.2 to 4.8 kilowatt-hours (kWh) of electricity. Factors such as power supply efficiency, cooling systems, and overclocking can also affect total consumption.
