    DOA with first mobo. Took almost 2 weeks to get new mobo. New mobo works great and looks great too.

    very straightforward, you plug things where they say you need to.

    This motherboard is good, but I just wish there were more addressable RGB 3-pin headers. There's only 2. But other than that, it houses all my components pretty well and the RGB lights are a small but nice touch.

    Great motherboard! goes well with the theme of my build. However the rgb app doesn't work very well, I had to go to the bios to change the colours.

    I love this motherboard, it makes IO glow. And the white, gray pattern design are really beautiful. Also the RGB is very nice, not overly done.

    There are 2 M.2 slots, one is a low speed 3 by 2. And the other one is highspeed 3 by 4.

    It took me sometime to figure out why my NvME was under performing. Like always, read your manual.

    The BIOS menu is fantastic, totally make sense and very easy to use. I love the Fan tunning function where it adjust the fan speed according the temperature.

    I definitely would recommend AsRock mobos to others. They did a good job putting it together.

    from completed build My Ryzen Upgrade

    Decent looking motherboard at a good price with just about enough features for me. RGB is controllable from the BIOS, which is much better than having to install yet another piece of software. 5 Fan headers, overclocking support, a couple m.2 slots, USB type-C on the rear I/O and RGB. Don't need much more. Kinda wish the USB 3 connector was at a right angle like on my last motherboard but its a small gripe with an otherwise good board.

    Easy to navigate. Easy to install. Digital camo and rgb was a nice touch for the price.

    A cheap but very well made B450 motherboard. Definitely form over function but it tends to my needs and I love the black and white camo, suits my build very well. RGB is not overly done and fits in nicely. BIOS is also easy to use, haven't had problems with this board.

    No issues with the BIOS (Score!). Got it so I had the Ryzen 3000 support if that upgrade comes to pass.

    from completed build Hidden Strength

    Good budget board. No issues with heat, has two m.2 slots which is rare for boards in this price range. Nice visuals, and RGB. Only complaint is I'd like to see dual bios and led for post codes.
