★★★★★Good board for the money, no frills, it works.
Works as it should. Like new condition. (I bought it refurbished) good board for the money. Bios is up to date enough for ryzen 9 builds without having to update. No frills on this board, only rbg is on the lower right of the board. Hidden behind the gfx card in my build. No other rbg on the board itself. Some want it some hate it. This is the meh in between for it ;)

★★★★★Works well with Ryzen 5900XT and Ubuntu
Board works well with my cursed 5900XT. Reasonable settings in BIOS (eg. virtualization on), nicer BIOS interface than some other brands. Went the easy way of disabling secureboot so that the amdgpu driver for linux would load, otherwise it wouldn't ... so that security measure works. USB-C port provides enough power to run a USB-C monitor. Both NVMe slots would happily sustain over 2500MB/s so loading large LLMs is fairly quick - 10s or less to load a model that would fit on any consumer GPU. Fan connectors seem to be better positioned and labeled than with other brands, and there appear to be both 3-pin and 4-pin RGB LED connectors if you're into that sort of thing, And a switch to turn all that stuff off, if you're not.

★★★★★Not bad for a refurb...
Its just the mainboard, and a driver cd, nothing else. No sata cables, no m.2 screws , and it is a refurb ,that being said . Board was pristine looking and well packed. Worked just fine.

★★★★★MAL PRODUCTO POCO RECOMENDABLE
Este producto llego defectuso me trate de comunicar con servicio al cliente con el proveedor y MSI y tan mal suerte que de 1000 placas salen 4 malas y me toco una de ellas, me demore un poco en reportar la falla pero no ofrecen si no una garantia de 3 meses por el producto
