### ⭐⭐⭐⭐⭐ Review
*by W***M on December 13, 2025*

NOTICE: When installing the audio and network drivers, you may need to use the CD included since that is how the drivers were able to be successfully installed for those components. Downloading from the website did not work, and the CD installer will auto detect and mark what drivers are installed. Great motherboard particularly if you get it sub $90. It has BT 5+ and comes with WIFI6 chip and an antenna which works tremendous compared to my external Wifi 6 adapter. No USB-C and only one HDMI port along with older video ports, but the trade offs are that it comes with Bluetooth and Wifi 6. It does have PCIE4 x16 and (1)PCIE4 x4 m.2 along with a PCIE3 x4 m.2. Highly recommend it if you want a B550 chipset micro-atx board with built in bluetooth and wifi 6 modules.
