Learn MoreDecoupling capacitors -- usually around 100 nF -- are usually placed as close as possible between the power and ground pins of an IC to absorb spikes on a power rail from interfering with the operation of the IC. Your Raspberry Pi should already have these capacitors added to all noise-sensitive components, so you don''t need to add any.
Learn MoreFrom the link you have the maximum current this power supply could do is 5V/3W=1.667A . Assuming that the capacitor and power supply resistances are so small. These caps need about 9 seconds to reach full charge - that is really a lot (Use V=(I x t)/C. This might burn the power supply if it does not have overcurrent protection.

Learn MoreAny regulated power supply needs to be designed to have low noise at the input and output to the regulator section. Getting noise low relies on selecting the right filter capacitor for your supply. Depending on the current, these capacitors can be quite large, or you may need to place a large number of capacitors in parallel.
