Don't ask why, but I have 5 Seasonic X Gold (2 x 650, 2 x 750, 1 x 1050), 1 Seasonic 760P and a Seasonic G 500w (so 7 Seasonics). My oldest PSU is a 2009 X650, that's been in 3 builds and has interstellar miles, even after 9 years there are no smells or wine from it, even the fan looks clean.
They have all been bullet proof except a Seasonic P 660 and a Seasonic G had a cold start issue and had to be returned, apparently the cold start issue on some Seasonics was/is quite common. Buying a good PSU is a bit like buying a good pair of shoes, you are going to pay more money but you may save money long term as the unit will last longer.
Also one last thing. If a PSU fails in a short time then unless it's just unlucky you know the PSU was poor quality I have Pioneer Hi-Fi amplifiers almost 30 years old and the PSU's in those are still running, so when you hear about computer PSU's failing in short time, compared to Japanese electronics of the 80's and 90's that are still working it's nonsense really. Of course it's not like anyone forgot how to build PSU's, more the case some PSU's are built really cheap plus all the planned obsolescence thats everywhere in the world.
