Computer Power Supply Calculator

If you plan to assemble your own computer from separate components, you will need a power supply powerful enough to run your computer depending on the configuration. This tool is a computer power supply calculator provided by Newegg, which lets you calculate the amount of watts your computer will maximally consume based on the configuration details of the components (CPU, Motherboards, Memory etc).

Just select your components and press “Calculate”.

    While this may be good for a first time builder, it isn’t necessarily the best option – if for no other reason than it only has older AMD processors and isn’t specific in any way.

    The eXtreme Power Supply Calculator is a much better choice if you want a better idea of what you need. It is constantly updated with the latest processors and graphics cards, and takes into account many more things which the newegg calculator doesn’t – PCI expansion cards, for example, or multiple kinds of hard drives, or water cooling kits (if that’s your thing).

    Hopefully this will help some people who are looking for a power calculator but want to be a little more accurate!
