Hello I am planning to build a rig with parts below. Please let me know which Power supply unit I should buy and if my combination is ok. Also, let me know if there are better alternative for the parts I have chosen.

I am using this rig for moderate browsing only but I will hook it up to 2 to 3 monitors. No gaming at all. I am building a new one because my current rig is very slow. I plan to use this rig as long as possible. Is there anything I could do to make it last longer? I bought my current rig in 2009 and it started to become slow/ lag in 2012 and I bought myself a laptop there. Now I want to go back to desktop but my rig is still slow after I have reformat the thing. Is there any part I can upgrade to make the lag comes later?

If not, how long can a rig with parts below go smoothly without lag?

I have flexible budget. I am planning to order my parts from lazada and amazon because I find seller charging higher price for parts listed below in the town I live.

Ryzen 3 1200
Asrock AB350 Pro4
G-skill ram ddr3 1600 4gbx2
Samsung 850 evo SSD 250gb
NZXT S340

Thanks in advance.
