Basic Build Overclocking Help

[nicholasvalentine]

I'm going to purchase my first components and I need some help, these are the parts I'm looking at:

MOBO: MSI B350M PRO-VDH;
CPU: 2200G;
RAM: G.Skill Ripjaws V - 2x4GB 2666MHz CL15 1.2V;
PSU: beQuiet Pure Power 10 400W;

and I wonder:

1. Can I safely overclock the RAM to 3200MHz?
2. Can I safely overclock the iGPU to 1600MHz on the stock cooler?
3: Will overclocking the above components decrease their longevity?
4. Corsair VS450 (2018) and Fortron Hexa+ 400W are both significantly cheaper than the PSU listed above, should I get one of these insted? Could this decrease my overclocking capabilities?
5. I plan to add an RX570 level GPU in the future, will 400W be enough?

Thank you for taking time to read this, I would really appreciate your help and suggestions

For all of your questions:
You can safely OC any part as long as voltages and temperatures are within manufacturer's recommendation limits. That will not result in any unusual component degradation.
Top OC limits can't be set for all components as they are always at least a bit different (Silicone lottery). Best you can do is to start small and check and test at every step and see where it gets you to. It's more of an art than science.
