Do I need to change my PSU? Corsair VS 550

[Celsius22]

This PSU is serving me for more than 1 year and 4 months with my i3 2100 - 6GB RAM and GTX 960 2GB but now I'll be upgrading to 1060 3gb. Do I need to change it to Seasonic S12II 520w? I know it's a low tier psu but this psu has been with my for 1 year and 4 months and no issue

Wattage wise the PSU is sufficient however not very efficient and could possibly let you down with the GPU upgrade. You can't go wrong with a Seasonic S12II for quality and rates very high for a bronze certified unit. If you have budget constraints then keep using the Corsair, it should be OK.
To be safe and for $80 at Newegg, I would choose to keep the Corsair for spares and upgrade to a Seasonic S12G 550W Gold certified unit.
