My Seasonic X is approaching nearly the 5 year mark and my EVGA G2s that I use in my home rigs are approaching the 4 year mark. Is it time to start looking at replacements? How long do the capacitors generally last? I am thinking of replacing my Seasonic X with a Corsair RMx and the home unit I will probably replace with the same supply (because of sleeved cables). So the question that I have is this - is it time yet to replace these units or am I good for another year or two?
