Hi have Seasonic SnowSilent 1050w purchased in early 2015.
Lately my PC hasnt been turning on. At first id have to remove USB thumb drive and charging Vape. Now with all cables unplugged it wouldnt turn on at all. Remedy was to unplug at wall and wait till caps discharged (i assume).

No system changes. No mobo error lights codes with GPU /RAM/ CPU etc. White Standby power LED is lit when plugged in & pc off.
Failing PSU? Under warranty for a long time (what 12 yrs or so, just a pain in the a**)

Thanks for advice.
