Do you really need that many CPU-Cores? Otherwise a 3700X 8-core may be better for yur needs (and cheaper)
There are rumors out the long missing B550 boards will hit stores in June, offering PCIe4 from the CPU for Graphics and 1x NVMe SSD, chipset offers additional PCIe3 lanes. No fan on chipset. The cheaper MSI x570 have at best mediocre VRM configs
Strike Corsair RAM and replace it with Crucial Ballistix RAM of the same speedgrade - better quality RAM
Powersupply is wayyyyy overdosed, if you want headroom stick to 650W.
No one should buy a plain 2060 with just 6GB VRAM anymore - aim for 2060Super or RX5700(XT)
I agree with dennis on switching the System Ram from Corsair to Crucial Ballistics Sport or Elite if you can afford it.... you can go with the 3600 RAM, but 3200 will work just as well
also, I'm with Drano on the Motherboard choice... ou of the 8 or 9 PCs I've built for others that request MSI boards, I have found them all to show irregularities with the voltage settings and even CPU output speed when running from a stock default bios settings.... even the SYSTEM RAM would clock higher and at weird speeds (MHz readings)
I would recommend sticking with ASUS, ASRock or Gigabyte motherboards..... ( I prefer ASUS myself )
The 750 Watt PSU isn't that bad "DEPENDING" on what Brand/Model it might be.... talking about quality here
Also, there has been a new RYZEN Driver update regarding the I/O Input-output controller driver.... they released one but it was supposedly giving some people problems but not others, so they released a newer version to have fixed that issue
and get ready for this years first Major WINDOWS 10 update...... it comes out in May ( Microsoft says 2 of these Major Big Updates are scheduled for Windows 10 each year ).....so I would recommend going into your update settings and setting both update setting options to hold off for 30 days before it downloads and installs..... this will buy you a little time so you can see if they have all the kinks worked out or if they will have to do aome patches to fix issues ( infact, anyone using windows 10, I recommend you postpone all your MS Windows 10 updates to 30 days, this will help you in the long run!)
As for your choice of MSI GPU, I've only heard good things regarding MSI's GPUs and think Drano can second me on that
Good Luck with your build and hope this helps
