A UPS isn't in your computer. A UPS is an uninterruptable power supply, essentially a battery backup for your computer. This device is rather useful if your power fail while your computer is running it allows you time to correctly shut down your computer, and some UPS's will actually shut your computer sour for you after a set period of time. Depending on the UPS some will run your computer from 5 minutes to an hour or more. What your cousin is describing is the foremost power supply in the computer.
