    Excellent fit for my gaming pc easily powers my 13900k with a mild overclock and my 4070ti with I mild overclock. The only thing to dislike are to PCI power cables being a 6 pin plus 2, it would be preferable if they came in the box with 8pins that were just straight 8pins with no extra cable ends to have to manage.

    Upgraded from the RM750x because I was having a lot of issues. This literally solved them for me and it is nice having the extra watts for when I upgrade the rest of my build.
