building my first gaming PC

[gfxgrim]

Hello everyone, I am currently looking into various parts to pick for my new PC and I don't know if anyone has better ideas or perhaps better parts to pick. This is what I have got as of right now: https://pcpartpicker.com/list/2Y3DQZ
I currently play on 1080p with a 144hz monitor. Just need to know if I'm not making any stupid mistakes here.

I swapped out the 1600 for a 2600. Newer generation and higher clock speeds for nearly the same price.
Then i changed the Ram for a 2x8GB 3000 mhz Kit. It is cheaper and still it is better to buy 2x8GB kits then buying 8Gb Sticks solo.
I also swapped the Motherboard to a 4XX Series to fully support the Ryzens features.

Also changed the Powersupply because i dont think you need to spend so much money on that. there are better PSUs out there for less.

Oh and i added a SSD if you dont have one already
