15 Mar 2015 22:00:00 Date when I bought it. 5 years. You think its his time?
Seasonic should be good for 10 years. My X900 lasted that long with no faults and I only changed it as it's 10 years old. It should also still be covered by the 10 year warranty if you do have a problem with it. Not sure how you go about testing the PSU at home though TBH. Maybe contact Seasonic and see what they say.
