Gaming PC power costs
GPU electricity cost calculators
Use official NVIDIA Total Graphics Power or AMD Typical Board Power as a reference, then estimate whole-PC wall power with adjustable GPU load, CPU/system overhead, PSU efficiency, usage time, and electricity price. State defaults use EIA residential rates for May 2026.

Rated graphics power comparison
| GPU | Vendor | Rated graphics power | Minimum system PSU |
|---|---|---|---|
| GeForce RTX 5090 | NVIDIA | 575 W | 1000 W |
| GeForce RTX 5080 | NVIDIA | 360 W | 850 W |
| GeForce RTX 5070 Ti | NVIDIA | 300 W | 750 W |
| GeForce RTX 5070 | NVIDIA | 250 W | 650 W |
| GeForce RTX 4090 | NVIDIA | 450 W | 850 W |
| GeForce RTX 4080 SUPER | NVIDIA | 320 W | 750 W |
| Radeon RX 9070 XT | AMD | 304 W | 750 W |
| Radeon RX 9070 | AMD | 220 W | 650 W |
| Radeon RX 9060 XT 16GB | AMD | 160 W | 450 W |
The listed graphics-power metric is vendor-specific: NVIDIA uses Total Graphics Power (TGP), while AMD uses Typical Board Power (TBP). PSU recommendations are not estimates of actual wall draw.
Why a GPU's wattage is not your PC's electricity use
A GPU power specification describes the graphics card, not the entire computer and not necessarily its average draw in a game. The CPU, motherboard, memory, storage, fans, pumps, USB devices and PSU losses also use power. Game load also varies by title, frame cap, resolution, settings and power limit.
Each GPU page therefore keeps the official rated graphics power separate from the adjustable whole-system estimate. For a measured answer, use a wall-power meter and enter that measured wattage in the general gaming PC calculator.
