Not entirely sure what you're getting at. The very basis of electromagnetic transformers involves electromagnetic fields and thus forces being applied to the components. When things are subject to forces, they move.

All electromagnetic transformers vibrate and whine. How much exactly is a matter of design and manufacturing tolerances, but it's no different to the buzzing you hear around overhead mains transformers and substations. Doesn't mean it's broken or about to blow up.
What I'm getting at is that in a cheap product like the poxy Superhub PSU, noise due to vibration should be regarded as a fault because vibration in such a device is not certain to be harmless - contrary to Heero's view.
