Review: Excellent Motherboard with Robust Build and Stylish Design - The Asus ROG Strix B550-F Gaming WiFi II motherboard arrived very well packaged, and installation was straightforward I only needed to buy a few extra standoffs for my case, which wasn’t a problem. This board exceeded my expectations with its beautiful design and solid, durable build. It feels robust and high-quality, and I’m confident it will last many years. Great value for money, especially for the performance it offers definitely a smart choice for anyone building a 3rd Gen Ryzen setup. Good Size, Excelente Performace, no Noises, Extreme stability and able to overclocking.
Review: built in bluetooth 5 and wifi 6 at an affordable price - 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.
