Outsourced S12III doesn't deserve Seasonic's name to its sticker.You offer an overkill PSU, I offer savings.
Its quality is below preceeding S12II.
And overall design was low end dozen+ years ago.
So could see it acceptable only for shoestring budget built.
You blame others from wasting budget into no use, yet push motherboard with CPU VRM from about £100 level boards.You can offer a better X570 board.
Heck, this £85 board has actually same Vcore VRM components as that £190 board:

And for limited budget build there's no reason to go for X570 board, when B550 gives same future proof PCIe v4 for graphics card and equally long CPU support.
For example £155 B550 Aorus Elite has basically same that MSI crushing VRM as X570 Aorus Elite
