GPU Power Consumption Calculator
Compare idle, gaming, and maximum GPU power draw, then convert watts into daily, monthly, and yearly energy use.
Power inputs
Consumption estimate
Average draw520 W
Daily energy3.12 kWh
Monthly energy93.6 kWh
Yearly energy1,138.8 kWh
GeForce RTX 5090 at gaming load for 6 hours per day uses about 1,138.8 kWh per year, or $204.98 at $0.18 per kWh.
Method and assumptions
Energy use is calculated from average watts divided by 1000, then multiplied by hours per day. Idle, gaming, and maximum power values come from the local GPU data file. Real draw varies by game engine, frame cap, undervolting, cooling, resolution, and driver power management.
