[Power Supply] How to Determine My Computer's Power Supply Wattage Requirement

If you're unsure about how to choose the correct wattage for your computer's power supply, you can base it on the wattage requirements of your CPU, GPU, and other key components such as memory, hard drive, and cooling system. For MSI users, you can utilize the MSI Official Website - Power Supply Calculator to select a power supply that meets your computer's wattage requirements.

Once you input your hardware combinations into the calculator, the page will suggest a suitable wattage for your power supply to the right and provide appropriate options.

Note:
Estimating the total wattage requirement of your entire system solely based on individual component wattages may not be accurate. It's recommended to input your complete hardware configuration for the most precise estimation.
