Startup Idea: Power Supply Life Tracking Software

Startup idea to develop a software that helps computer repair technicians (and potentially users too) to monitor in real-time the life of power supplies in desktops, laptops and mobile devices. The goal is to provide an estimation of a device's power supply life expectancy, thereby allowing technicians to give timely recommendations for replacements.

I work repairing computers on a daily basis even mobile phones at times. There are about 6 other people that work here with me.

The problem lies that I need software that helps me keep track of power supply life. Power supplies are one of the most important parts of any computer. Being able to know how much life is left in a power supply would be a god send. I feel like this is the truth and I need it to be like that overall.

The ideal solution is being able to know this , in this way I can recommend a new power supply!. It would be amazing! Of course, I know as of now, this is not possible but finding a way to do this in the future would be a huge achievement for mankind.
