Can the power supply be a capacitor

It depends on the voltage ratings of the capacitor and the power supply - and how much current the power supply can deliver. If the the power supply voltage is higher than the rated voltage of the capacitor, then the capacitor will be damaged. Some capacitors will fail and short circuit when you exceed the voltage rating. If the power supply ...

Is there any downside to using a larger than needed smoothing capacitor?

It''s a small plus however, as even doubling the size of the capacitor will only (roughly) halve the ripple. Anything downstream of a large capacitor will need to have significant Power Supply Rejection Ratio (PSRR) to cope with the ripple. There are cheaper ways of improving this by a factor of two than doubling the size of the Big Filtering ...
