How to lower the cost of running a gaming PC

A gaming PC's power draw depends on the GPU and CPU and on how demanding the game is. A mid-range build typically pulls around 400–500W from the wall during gaming, while high-end systems with top-tier graphics cards can exceed 700–800W. Idle and desktop use is much lower, often 60–120W. The monitor adds another 30–80W.

  • Cap frame rates to your monitor's refresh rate — rendering frames you can't see wastes power.
  • Use your GPU's power-limit or efficiency settings for a large power cut with a small performance loss.
  • Set the PC to sleep after 15–30 minutes of inactivity.
