The Central Processing Unit (CPU) and Graphics Processing Unit (GPU) are the primary power consumers, often drawing between 65W to over 300W each depending on the model.
The calculator will then estimate the total power consumption of your system in watts.
| Component | Typical Peak Draw (Watts) | |------------------|---------------------------| | CPU (Ryzen 7 7800X3D) | 90 | | GPU (RTX 4070 Ti) | 285 | | Motherboard + RAM | 40 | | SSD + HDD | 15 | | 3x 120mm fans + AIO | 15 | | Peripherals (USB) | 10 | | | 455 W |
To use a watt computer calculator, you'll typically need to provide information about your computer's components, such as:
