It is then common practice to give some allowance in the rated voltage of the capacitor (e.g. 400 V rated voltage of capacitors for a 380 V network), as the performance and life of capacitor may be adversely affected if they work above rated voltage.
The power rating and the capacitance are two important aspects to be considered while selecting the smoothing capacitor. The power rating must be greater than the off load output voltage of the power supply.
This application note describes the selection considerations of output capacitors, based on load transient and output impedance of processors power rails. Presently, there are no specific tools available for non-Intel processor output capacitors selection in multiphase designs.
A capacitor unit is normally designed for single phase. The capacitor should be capable of smooth operation upto 110% of rated peak phase voltage of the system and also it should be capable of operation 120% of rated rms phase voltage that means, 120% of times of peak phase voltage. Capacitor unit are normally rated with its KVAR ratings.
System Voltage Tolerance: Capacitor banks must operate smoothly at up to 110% of the rated peak phase voltage and 120% of the rated RMS phase voltage. KVAR Rating: Capacitor units are rated by their KVAR values, which determine the reactive power they can provide to the system.
Capacitors don't really dissipate a lot of real power when used well under their voltage rating. They do though however generate reactive power but that has nothing to do with real power and hence heat. Voltage rating is more important than 'power' rating. @PlasmaHH Actually not.

How to select rated voltage of a RF capacitor
A 33 pF capacitor at 850 MHz has an impedance of about 6 ohms. If it is passing a power of 33 dBm (about 2 watts) to a 50 ohm load, the voltage seen across the 50 ohm is $sqrt{2times 50}$ = 10 volts RMS. The 50 ohm current will be 200 mA RMS and this will drop a peak voltage of about 1.7 volts across the series 33 pF capacitor.
