    great!

    Great product, as described, mounted on a cooler masterbox E -500L.
    Installed a ryzen 5.2600x, a gtx 1030, a corsair vengeance lpx low profile 2x8G 3200 mhz ram and a crucial ssd bx 480. The card does the job perfectly, no compatibility problems or anything else.
    I've been using it for a while now, but I'm not sure if it's a good idea to get a dvd player because a dvd is included in the box and it allows you to download all the asus softwares (ai suite lll, ez update...) which are not available on the asus website anymore. (I think there are even bios updates but I'm not sure).

    Very good value for money.

    I highly recommend this product.

    A good little map

    Bought to mount fast desktop PCs, this motherboard is perfect for the price :)

    It works perfectly with an R5, 16GB of ram at 3200 received nickel the bios is sufficient and easy to take in hand. The M2 boot is a great addition to the PC and nothing less!

    I recommend

    Received quickly despite the confinement (about 5 days), but very good product, with a Ryzen 5 2600X Wraith Spire Edition and 2x8Go Corsair Vengeance LPX Series Low Profile DDR4 2666 Mhz CL15, it fits perfectly. The overclock system is correct too.

    ADVANTAGE: Realtek audio drivers, AMD chipset and Realtek LAN included in the installation CD.

    Bémol : Remember to set the frequency of your RAM in the 1st startup. I have 2666 Mhz and it recognized me in 2133 Mhz.

    TOP motherboard for office and games

    Bought this CM with AMD Ryzen 5 2600X Wraith Spire Edition (3.6 GHz) and G.Skill RipJaws 5 Series Black 16 GB (2x 8 GB) DDR4 3200 MHz CL16 to replace an old ASUS M4N 78 PRO with AMD Athlon X2 64 that was starting to get stale because of power hungry websites.
    Very good for office work, watching movies and making music by connecting a MIDI instrument via USB audio interface.
    The only problem is that the UEFI BIOS has a problem with the boot image, which remains on the boot image for 30s to 1mn before launching LINUX. If the IT department can help, thank you.
    I'm not sure if I'm going to be able to do this, but I'm sure I'll be able to do it. Now, too much top.

    Good product

    Good motherboard. The configuration and O/C options are sufficient for my taste.
    The only drawback is that due to the format of the new graphics cards (2 slots), the PCIe 1x slot located under the PCIe 16x is unusable. The second one is accessible and my asus wifi card is just under the RTX 2070's fans. It may be necessary to provide an extension (riser) to move the ports and place the hardware connected to the PCIe 1x lower if we want to optimize the airflow.

    The supplied quick installation manual is clear and easy to follow. Slots are easy to access. No reliability or performance issues detected after two months of use.

    It's Asus!

    I've been using it for a while now, but it's a very good little motherboard, robust, reliable (it took a power supply failure without flinching), and the small screw for the M2 is included, which is not the case with all of them.
    The small screw for the M2 is provided which is not the case for all...
    The 4 RAM slots to go up to 64GB allows you to see quite large and especially the BIOS updates in one click to support the Ryzen next gen... For this price, it's all good!

    I recommend

    It does the job

    I took this motherboard and paired it with a Ryzen 5 2600 and 16GB of DDR4 2666. Nothing to say. For a half-gaming, half-multimedia configuration, it runs very well. I discovered after the purchase that it has an M.2 port. I will certainly add an SSD to it soon.

    Also satisfactory in gaming configuration

    Coupled with a ryzen 5 2600 and an RTX2070 and 16GB of RAM at 2800MHz, the CM manages the cooling of the 2 case fans + the CPU fan very well, with customisable operating curves in a complete and ergonomic bios.

    Asus FTW

    This motherboard seems very good and robust. I took it for a gamer configuration coupled with a Ryzen 5 2600. I have very good performance in games.

    I had hesitated a lot between this model and another one (still Asus) but gamer oriented and more expensive. I don't regret my choice, especially since the only advantage of the gaming model is that you can plug in a 2nd CG (its and a slightly different design). So if you don't plan to use 2 CGs on the same PC, this model is perfect.
