Thanks for the tips. I've read recommendations of the ASRock B650 instead of the board I opted for, which costs only slightly more. AFAIK the only downsides to the A620M are no support for PBO + Curve Optimizer and no RGB headers. Those don't matter to me at all, since I don't intend to overclock and have no need to make my PC look fancy, I look at the screen most of the time, and not what's under the table :).. That said, I admit that the 7600X probably may have been a tiny bit overkill pairing with the board, but w/e, I like to live on the edge.
I opted for that Corsair PSU because I found a good deal and the fact that cable management (unless in areas where necessary) was and isn't really a priority, so Fully or Semi modular it was. Other than that, no forethought was put into it.
EDIT:
Oh right forgot to mention that PcPartPicker's estimated wattage also guided my PSU purchase, the total estimate was at 530W, so I just multiplied it by 1.25. I'm currently second-guessing my PSU choice now..
