What causes PSU to fail?

To summarize, high quality PSUs can fail for the following reasons: Broken MLCC components. Long mounting PCB screws. Damaged ICs and FETs because of soldering-wave issues.

What is the lifespan of a PSU?

Power supplies can last a decent lifespan (4-5 years and sometimes longer). It all depends on the quality. The simple PSU would last 2-3 years.

What kills a PSU?

Distinguished. A non good brand PSU can die for many reasons: Power surge (aka lights going out at home or high volt spike) is the most common. Better Psu brands normally are quite fine vs those.
