Some general advice: cut as many expenses as you can and get a higher end GPU if your only performance demanding activitity will be gaming. You can get a 4070 at this PC budget if you make some cuts elsewhere. Although I understand if you prefer a fancy case - and motherboard with all the ports, I'd personally move $150 from those two towards your GPU.

Regardless of if you do or not, that PSU looks sketchy. I see some Reddit threads saying that, while it's electrically good, the fan is super loud. Always get a PSU that went through rigorous testing and the wider enthousiast community backs as reliable in every way: power quality, reliability, warranty honor. Most gold rated Seasonics and Corsairs will do fine in those categories. You don't need more than 600W for a build in this range, so you can go for a cheaper wattage option.

While AM4 is still a very cost-effective platform, I don't get why you want a 5700G when you're not going to use the iGPU. The 5700X supports PCIe 4 and has more cache.
