When replacing a bad computer power supply can you install a bigger one and not harm the computer?

Don't worry... more watts available is unnecessary, but cannot harm your computer. Less watts than needed could harm your computer.

For dealing with motherboard and other devices you should usually ground yourself. However when you deal with your power supply make sure you do not earth yourself as this could harm your power supply or even you.
