    I started to write a description then I realized I have no idea what power supply this cap goes into.

    Transformer step down?
    Single diode or bridge or what?
    Switching supply?

    If you Google "power supply filter capacitor calculation" you will get plenty of hits with examples.

    If you're talking about the classic wall wart, transformer + bridge rectifier + filter cap, then you might find this post useful, along with the thread.
