There are a number of possibilities, including dirty power at your location as the most likely suspect. Transients, harmonics and brownouts will reduce the lifespan of PSUs, and such anomalies can be caused by a number of factors including under-spec wiring, large motors being started, unfiltered VFD/inverter drives, other inductive loads such as UPS units, and more.
It's also possible that some component in your systems is causing an issue, such as component(s) with inordinately high leakage causing out-of-spec power draw and additional heat.
Topic: 4 dead PSUs, there HAS to be a commonly failing component - page 2. (Read 2854 times)
In the past year I've had over 4 "out of warranty" PSUs die on me. A 750w Silverstone, 450w and 480w Antecs, a 400w Enermax and a few no name ones.
So now I've got a box of dead PSUs and I'm thinking, there's got to be a particular component that's responsible for a large portion of the failures.
And yeah, I've heard all the "Deadly Internal voltage" warnings etc. I always wait a day before opening one up, but I've pulled apart quite a few to recover the fans, so now I'm looking to actually repair them.
