Power cords are generally not very flexible, and can easily carry acoustic vibrations directly into connected equipment. They bypass whatever isolation the rack and equipment supports provide. This makes it important to dress the cords properly in order to avoid acoustic issues.
Power cords, as other audio cables, also act as electrical resonators. They generally are made of good conductors and insulators, and the cable impedances are generally not matched by the connectors, house wiring, or equipment power supplies. This means they have resonant modes, usually in the UHF band. The resonances modify the overall RF noise environment of the setup. In particular, the power cord resonances can couple energy into other audio cables.
