What capaacitor do I use?

I have read tons of stuff but never anything about how to choose a capacitor value in a power supply circuit. Is there an equation / law / etc. that lets you know what value to incorporate. I understand the voltage part, but how do you decide what capacitance is needed to smooth out the supply?

What capacitor do I use? - A general rule.

An excepted general rule of what capacitor to use in a psu is 1000uF per amp of current to be supplied by the psu as a minimum.
