What causes PSU failure?

The Reasons Behind Problems In Quality PSUs Bad handling (i.e. improper PCB stacking during the manufacturing process) PCB bending (which can happen during the solder-wave process, if extreme heat is applied) Careless soldering repairs on the PCB.

How often should PSU be replaced?
