Disappointed with performance, bad luck?
I wanted to take advantage of a promotional offer to update my "old" Seasonic S12-500 (almost 15 years of service) during a configuration upgrade. It was a bad idea because the 12V oscillates between 9.5 and 10.8V max ! I was able to realize this after a suspicious crash of the PC, something that had not happened to me for a long time. I may have fallen on a bad power supply but I don't think I'll take the risk so I'll send my S12 back and reassemble it until it's really "out of date". (in the end 500W despite a slightly less good performance will be enough for me)
