Corsair RM850xI'd go for the MSI one just cuz of looks.
Why not go with a 3080?
Are you really gonna use that 3090 to its max?
What psu do u have?
Well zotac one is 300 dollar one cheaper but there are issues related to it (heating issues) plus according to the reviews it's performance is not even exceeding the FE.MSI usually makes better cards than Zotac. I would say if they both have the same warranty period, go for the cheapest. The performance difference would be negligible.
300 dollar difference between the twoThe trinity models have definitely been one of the worst 3000 series' unfortunately, for it's cooling and OC capability.
So out of those two, I'd say get the gaming x
