Power Supply Calculator

This tool helps you calculate the power supply wattage you need for your computer.

This calculator helps you determine the necessary wattage for your Power Supply Unit (PSU) based on the components of your system.

How to Use

Enter the power consumption of your CPU in watts.
Enter the power consumption of your GPU in watts.
Enter the number of memory (RAM) units in your system.
Enter the power consumption per memory unit in watts.
Enter the number of storage units (HDD/SSD) in your system.
Enter the power consumption per storage unit in watts.
Enter the power consumption of any additional components, such as fans, in watts.
Enter the efficiency factor of your PSU (between 80% and 100%).
Click the “Calculate” button to see the total power consumption and the required PSU wattage.

How it Calculates

The calculator sums up the power consumption of the CPU, GPU, memory units, storage units, and any additional components. It then divides the total power consumption by the efficiency factor to give you the required PSU wattage. For example, if your components consume a total of 400 watts and your PSU has an efficiency factor of 85%, the required PSU wattage would be approximately 470 watts (400 / 0.85).

Limitations

This calculator assumes standard values and may not account for all variations in component power consumption.
Always consult with your component manufacturer for exact power requirements.
PSU efficiency can vary with load, so consider a margin for error.
