    Great motherboard but antenna cable too short

    Rather easy to install. Bluetooth works really well: with a wireless headset, I don’t lose the sound even 2 rooms away at the other end of my apartment (small 32m² apartment).
    I haven’t tried Wifi but the Ethernet connection is much faster than my previous motherboard.
    Its only drawback for me is the length of the antenna cable, which is too short for my current use: it’s made to be placed on the tower and not on a table higher than the tower (perfect for a tower placed on a table, less good for a tower under the desk if there’s no space on the tower for the antenna). The antenna ports are only compatible with this MSI antenna, so it’s not possible to buy another antenna with a longer cable to replace it (even from MSI), so I’m removing one star.

    Easy and effective

    Great choice for my new build! The MSI MAG B850 TOMAHAWK MAX WIFI offers an excellent balance between high-end features and a reasonable budget. The support for AMD AM5 processors (Ryzen 7000 and 9000), DDR5 support up to ~8400 MT/s in overclock mode, the two M.2 PCIe 5.0 slots, the 5 GbE network card and Wi-Fi 7 are simply top-notch!

    Installation went very smoothly: the card is well thought-out for builders (EZ PCIe release, Clear CMOS / BIOS Flash buttons, etc.).

    The sober black design + discreet buttons works really well, and you get all the connectivity you need without any frills. The value for money is clearly excellent.

    PERFORMANCE TOP AND MSI QUALITY

    The card is really top-notch! because it has several advantages:
    - Several M2 spaces
    - Good prices
    - All the latest standards
    - WIFI 7 with aerials included
    - PCI EXPRESS 5.0
    - Eject button for pci express port
    - Sober and no fuss (rgb)

    On the other hand, it has no RGB at all, which may be a problem for some before making a purchase, but the main thing is performance.

    In conclusion, I'm satisfied, especially as it's the latest generation of Intel socket at a reasonable price.
