Individual pedals especially distortions and digital delays are likely to have some kind of power line filtering but without an isolated power supply that is one where each output powers one pedal only and the power lines do not cross it s possible to pick up noise from other pedals sharing the same power source.
Isolated output pedal power supply.

Expensive power supply advantages.
The outputs are fully isolated and extremely quiet and accommodate a variety of voltage and current requirements two 9v outputs at 100ma two 9v outputs at 300ma two 9v outputs at 450ma two 18v outputs at 250ma and in one particularly cool feature two 6 15v variable voltage.
Can be placed close to pedals quietly the ones with toroidal transformers all outputs are isolated so every pedal can be isolated from everything else good but rarely necessary expensive power supply disadvantages.
The down side is there is no isolation between the input and output.
