If there was a damaged or improperly crimped pin in the connector, the unwanted resistance would've caused heating, which would've led to contact damage/oxidation, which would've led to more resistance. Lather, rinse, repeat, and you eventually have a burned out connector. If that was the only problem, I'd be surprised if it killed the entire PSU though. Does the PSU at least attempt to power up (PSU fan spins)? Does this motherboard have a LED to indicate it is receiving juice over the main (ATX) power connector?
I've owned exactly one Silverstone PSU myself. The PSU fan whined when the system was idling or at low load (fan at minimum RPM); I'm guessing some sort of issue with the way they were controlling the fan RPM. This is exactly the time when you don't want your PSU to make noise, since everything else is quiet! I never bought another Silverstone PSU.
My thoughts exactly, a loose connection just making small arcs over time. But this machine was in since 2013! It was also up on a shelf as an HTPC type deal in an office. They claimed it went bad a few weeks ago after some power failures, they had removed the UPS from the system a few years ago without telling me, but it's not an office I do work for anymore.
I have used about a total of 6 silverstone, so this is the 3rd one to have some sort of issues. 2 of those three are the same model. They only have 2 wires going to the fan which is soldered on. Was going to do a transplant last night but decided I didn't want to play around with soldering and likely live capacitors at 5am and no coffee.
Johnny seems to have a newer version than I have of that supply, I notice quite a few thing are different. The components inside mine seem like decent quality, it is the solder jobs that I'm blown away by. The pictures of their 450 looks like gods work in comparison to mine! He did mention that Sirfa's solders have got much better over the years and his is from 2017? So I'd assume that the unit I have is also from them prior to learning to solder. I'll take some pics for sure and post up. Also, different brand fan in this unit.
