The biggest thing is I'd say get at least a 750w if not a 1000w PSU. I did some research for when I got my 6950xt and it (at least used to) spike the power consumption to where you can get framerate issues without a 1000w Psu. If you want to forgo that at least get 750w so you're in the better range for PSU efficiency of around 80%.
Based on your other comment I would like to ask if you need a 12 core cpu you could sacrifice a little bit of core count and get a 7800x3d (if they're in stock/a reasonable price) or even keep the core count and get a 7950x3d and you'll get a nice ~20fps bump in most games. You could go with the classic 212 Evo for the CPU cooler to bring down costs a bit to meet your budget.
Overall everything outside of the PSU size looks good, you have the right speed of ram and all that
