ASRock has done a fine job with the X399 Taichi. It looks good, feels like a quality piece of hardware and packs all the features you can expect at this price point. If you choose to overclock your Threadripper you will have to do the job manually but...
I am unable to fault the board, even if I were to be really picky I'd say it lacks detailed overclock tweak settings and perhaps RGB LED that aren't attractive but I do think that would be unjustified.If you're looking for an excellent X399 board then...
The X399 Taichi performance wins in important categories earns this beautiful motherboard a thumbs up. Great layout, performance, aesthetics, and a low-price help elevate this motherboard enough to get our approval, but not quite enough to achieve Editor's Choice status.
