I'd personally ditch the ram, get a 64GB 6000C30 kit if you want more than 32gb, but for general gaming 32gb is fine. I'd up the psu..seen plenty of reviews with gpu pulling very close to 600w..cpu, 9800X3d still uses more power than the 7800x3d and can pull upto 180..then you have fans etc...if everything is maxed, then you'll be pulling well over 800w...I'd just buy a psu where it's not running at >80% use....always went with rule of thumb run the psu at 50%, generally in it's most efficient spot and less stress on it so longer lifespan. a 1200W would be running at 66% or 1300 at 61%....yes and other times it wont be running max, so wont be up there...just my take
