Re: Seasonic X 850W not turning on

The blue marked CapXon was shorted in the upper right corner. He gave a short circuit on the line of 12 volts. In the most inconvenient place in the entire power supply. When burned, it scattered completely. If the photos are preserved - lay out. As for the capacitors - I had a similar failure with the Xilence power supply, but there, at least from the factory, the polarity was reversed during installation. I was looking for schemes, but I did not find anything for this company. All intuitive repairs

Good evening
Thank you for the files provided. Now I have a lot of Seasonic products at work - but there is no information at all.
One of the problems encountered is a short circuit on the 12 volt line. I assumed that one of the 4 field-effect transistors on the rectifier board was to blame. We take soldering irons and in four hands we solder the module. But the short was not there. It was to blame - polymer electrolytic capacitor. Which when defective - flew out of the room. But polymer - very durable capacitors.
Someone can...
