went for a RM850x(new one , where fan side is a lot more perforated as comes with 10yrs warranty) in my build. Got a 3080fe also but hopefully if I upgrade anything in the future, it'll still be ok. I actually had the same mobo but switched to a b550 in the end. didn't see much point as wasn't going to be using all the gen 4 pcie lanes that x570 provides(but Tomahawk still great board so if you're happy with X570, it's still the oneI'd go for)
