PSU lifespan?

[bakes0310]

I have a 3 year old superflower 1000w platinum PSU. How long should you keep a PSU for, what's the first signs that a PSU is dieing?

Nothing wrong with mine but I would like to save some money on a new build next year by not getting an expensive PSU.

Thanks for the quick replies. Would you say I have a good quality PSU?
