How much does a gaming PC cost to run?
A 400W load for 4 hours daily uses 1.6 kWh, about $8 a month plus monitor. High-end rigs under load reach 600 to 800W.
Does the monitor matter?
A 27-inch monitor adds 25 to 40W. Ultrawides and high-brightness HDR panels add more.
Do consoles use less?
PS5 and Xbox Series X draw 150 to 220W gaming, far less than a gaming desktop at similar fidelity.
How can I cut PC energy?
Enable sleep after 15 minutes, cap frame rates, and undervolt the GPU for 10 to 20 percent savings.
