Seasonic PSUs and Corsair PSUs are all I’ve ever used for the past twenty years. In that time I’ve had one failure: a twelve-year-old power supply that had not been powered up for over a year. The failure was quite spectacular and also quite smoky. The house smelled of burnt up capacitors for days!
I wouldn’t “throw out the baby with the bathwater” in regard to Seasonic. I have never once had one fail, either at home or at work. The failure of the ancient Corsair was entirely on me; I know better!
