    Good entry level motherboard, maybe lacks some connections for the fans but otherwise great!

    Upgrade old PC

    Motherboard associated with a Ryzen 5 3600, a Western Digital WD_Black SN770 1Tb SSD and G.Skill RipJaws Series 5 Black 16Gb memory (2x 8Gb), installation of W10 and 3D / CNC software without any problem.
    I withdraw one star for the fact that only 4 USB2 ports are available internally (the tower and the card reader require 5)
    Apart from this detail this configuration is so far perfect.

    Do the job, beware of recent processors.

    Good motherboard that meets my expectations once the BIOS issues are resolved.

    I wanted to put a ryzen 5 5600g on it but I had to flash the BIOS. So disassembled a 3600x from another computer, made a CMOS clear with a screwdriver and swapped CPUs to access the BIOS. This, after suspecting and searching for a hardware failure and coming to the conclusion that a CMOS clear allowed the 3600x to finally boot.

    I wish ASUS and/or LDLC would have made it easier for me to find out about the 5600g incompatibility at the time of purchase so that I could waste less time or switch to another product.

    But hey, all's well that ends well!
