To calculate the correct wattage of the power supply we use the peak power consumption of each component in your configuration according to the manufacturer's information.

You can save your configuration and load it anytime if needed.

The calculated maximum wattage demand could differ from the true power consumption of your system. Our calculated value will allow you to run all of your components at full load.
The highest efficiency is reached between 50% and 80% loading of the power supply, for your system to run under the best circumstances.
Now you have the possibility to refine the result and choose the main criteria your preferences of the PSU that are most important for your individual requirements, such as silence, efficiency, cable management. Additionally you can adjust the price bar to find the perfect PSU within your preferred price class.
