    Good motherboard

    Attractive design, well equipped in terms of connection ports. The only drawback is the very basic manual provided; you have to go to the ASUS website to download a more detailed manual.

    Practical

    I like this card, it has a good number of USB ports, audio, WiFi, internal connectors for fans, etc.
    It had been years (decades) since I had built a PC, and I really enjoyed it; it worked fine from the first time I turned it on.
    My configuration: AMD Ryzen 7 9700X, Noctua NH-U12S, Kingston FURY Beast RGB 32 GB (2 x 16 GB) DDR5 6000 MHz, Samsung SSD 9100 PRO M.2 PCIe NVMe 2 TB, MSI GeForce RTX 5060 Ti 16G VENTUS 2X OC PLUS, be quiet! Pure Power 13 M 850W 80PLUS Gold
