What causes PSU to fail?

The main killer for a PSU is dirtiness. Physical dirt can clog fans and coat heatsinks which will impair heat dispersal and can cause premature component failure. Dirty mains power will damage components slowly over time or all at once, over and undervoltages can be ruinous to parts.
