@Olmill If that was the case, then the no-break failed big time.
I have no experience with no-breaks, don't need them in Germany, fortunately.
The broken part looks like a ceramic capacitor, these don't really go bad over time like electrolytic caps.
"A high-energy surge may crack the ceramic and let in moisture, providing a conductive path."

@hideki What brand is that PSU? I only buy Seasonic. My PC is also plugged into pic. related - just in case. Even though the breaker box is modern.
@hideki
Might have been a voltage spike in the mains.
