- Good motherboard - Sean, 12 March 2026
The wifi and bluetooth works well and the board feels premium. Other than that, it's an AM4 motherboard. Nothing special, but it works.
- Great Motherboard - Kobus, 16 January 2026
Very easy to install and the manual helps out a lot, in Modimolle there aren't any pc shops anymore and must buy online and install it DIY but for me I take my time and had no problems. Pairs well with the Ryzen 5 5600XT I bought with it. If you got AMD GPU activate the Rebar option in bios for more free fps.
- Awesome - Johan, 6 December 2025
My First experince with AMD tech, and Asus. Was really great to build this PC. The user manual made it a breeze.
- Performance is much better - Colby, 3 November 2025
This Motherboard is great , my gaming experience has leveled up , I get much more consistent fps on games now , Upgraded from a B450M Mortar Max
- Great upgrade - Grant, 24 October 2025
Works perfectly...as mentioned the BT and WiFi drivers are a bit of a pita to find but other than that all good.
- Loving it. - Teboho, 10 July 2025
Worked out of the box with a Ryzen 5 5600. Has enough usb connections, feels premium. I'm loving it.
- The wifi drivers are wrong though. - Spot On, 24 March 2025
Features are good for the price, but run into a problem since Asus is listing the wrong wifi adapter in their website for this motherboard, so their drivers won't work. Same goes for Bluetooth. After some searching I found that the correct adapter is Realtek 8852BE.
