    Meets my expectations

    I was already familiar with this card, which meets my expectations perfectly for a machine that is both gamer-oriented and "office-oriented".
    Nevertheless, I would like to underline the efficiency of the salesman in Villefranche who was able to answer a few questions about the compatibility of this card with my case (for example, he warned me that the card does not manage the usb-c present on my tower, the rams I was considering and the ventirad).

    No complaints

    I brought my tower with me, not knowing how to improve it, and the sales staff advised me with the best parts available, within my budget, and the assembly was perfect. Frankly, I'm very happy with my tower!

    Warning: wifi and bluetooth drivers problem

    The Wifi and Bluetooth drivers on this motherboard do not match those listed on the ASUS website for this model.
    - for bluetooth I used the "PRIME X670-P WIFI-CSM" bluetooth drivers.
    - for wifi I used the drivers "WiFi_Realtek_v6001.15.159.0".

    Motherboard evaluation

    I went to the shop in a hurry as my motherboard bought on Amazon was faulty. I was given a very warm welcome and clear information. I went back a second time the same day for another part to assemble my PC. I recommend LDLC

    Ready for a clean, correct and sustainable configuration

    Combined with a Ryzen 7 5800X, cooled by a Thermalright Assassin, mounted with g.skill ddr4 Trident 32gb cas16 Royal, a good Seasonic power supply, a doubled m.2 nvme and a few sata disks (which is why I took this asus tuf b550 (for a few more SATA ports), a small rtx 2080ti, all in a Lian-Li case, this motherboard is a very good compromise for durability and performance.

    Perfect, well, almost like everything else in life.

    Perfection is just a pipe dream!
    But this is very close to that goal, perfection in this generation of CPU motherboards from AMD.
    Easy to install.
    Complete
    6 SATA!
    And solid and rigid...

    One of the latest cards with 6 SATA pots

    CPUs and chipsets are evolving. But I still need to connect my 6 hard drives for my backups. And it's no longer easy to find 6 connectors on a motherboard. This ASUS motherboard exudes quality and also has two M.2 PCIe slots: ideal for installing an OS while keeping the 6 SATA ports free for storage. Quality BIOS, everything's good!
