i need help for pc building

Solution
Lose the PSU - that's not a good unit, and for a Ryzen rig you should have at minimum DDR4-3000 or DDR4-3200, but do not compromise on the RAM speed. Also that SSD will fill up very quickly, you would need to get something with a higher capacity storage level. I would get something like this:

That's a little bit more but will be a much better system in the long run.
