Hey guys, I bought a Seasonic S12II 620 W PSU about a month ago. It worked fine though while heavy usage the fan did get a bit louder, especially while playing counter strike. None of this seriously bothered me, but tonight there was an explosion from somewhere behind the pc, and a blue spark seemed to appear too. Now since it was so quick, I cant be sure what it was, but I suspect it was the PSU. However what I find strange is that about 5 seconds after it happened, the pc restarted and everything seems to be working fine. How do I make sure everything is alright?
