Frequently asked questions

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.
