GeForce RTX 5080 electricity cost
NVIDIA lists the GeForce RTX 5080 at 360 W Total Graphics Power. That is a graphics-card reference specification, not a whole-PC wall-power measurement. The calculator below models the rest of the system separately.
Whole-system reference calculator
Estimate a GeForce RTX 5080 PC's electricity cost
Reference model only. Rated GPU power is not the same as measured gaming power or whole-PC wall draw. Defaults assume 80% of the GPU's rated power, 150 W for CPU and other components, and 90% PSU efficiency. Adjust the inputs or use a wall-power meter for a better estimate.

360 W Total Graphics Power
PowerCostAtlas uses the graphics-power figure published by NVIDIA. Add-in-board models, power limits and real workloads can differ.
Default whole-PC assumptions
80% GPU load + 150 W system load
The reference estimate assumes the GPU averages 80% of rated graphics power, the rest of the PC uses 150 W internally, and the PSU is 90% efficient. These are modeling assumptions, not vendor specifications.
State electricity-price effect
Same GeForce RTX 5080 reference PC, different state rate
All examples use the same default model: 80% of rated GPU power, 150 W other internal load, 90% PSU efficiency, 4 gaming hours/day, 30 days.
How to get a more realistic GeForce RTX 5080 estimate
Start by matching your actual gaming time. If you know the wall-power draw of your PC from a meter or review measurement, the general Gaming PC Electricity Cost calculator is the most direct option. Otherwise, change GPU utilization and other-system watts here to reflect your workload and CPU.
Do not use the power-supply wattage as electricity consumption. A 850 W PSU recommendation describes capacity headroom for a compatible system; the computer does not continuously draw 850 W.
Formula used
Estimated GPU draw = rated graphics power × GPU-load percentage. Estimated internal system load = GPU draw + other system watts. Estimated wall draw = internal load ÷ PSU efficiency. Monthly energy then equals wall kilowatts × hours/day × days, and electricity cost equals energy × the selected cents-per-kWh rate.
