ASUS Prime B550M-A WiFi II AMD Micro ATX Motherboard with PCIe 4.0, WiFi 6, ECC Memory

Solid board, everything worked out of the box. Driver update tool that tries to install also tries to launch automatically run under every profile but requires admin credentials to do so, so I uninstalled that.

TBH, I picked this board mainly to pair with my Ryzen 5, and the build experience was better than expected. The biggest highlight has to be the integrated Wi-Fi and Bluetooth. It saved me from the hassle of running cables at home; the signal is rock solid, and it saved me the cost of an extra network card—10/10, worth it! The BIOS is super user-friendly, allowing even a beginner builder to easily set up XMP. No cap. Tbh, the port selection is kinda basic, but it’s def sufficient for daily use. The PCIe 4.0 support gives me peace of mind for future SSD upgrades. If your priority is stability, ease of use, and a no-fuss setup, this M-ATX board is a top-tier value pick among B550s. Highly recommended for stable performance-seekers like me! Goated board.

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.

I wanted to test this for a while before reviewing to make sure I didn't have any unexpected surprises. It has amazing features, GREAT capacity, both with storage and memory, especially from a Micro ATX board. The wifi seems pretty solid giving a consistant 500-800Mbps download speed on a shared gigabit connection, while the ethernet connection seems to pull a solid 900+Mbps speed. I am running on 2x8 3200 MHz speed CL16 memory but according to the official specs, it supports up to 128gigs (4x32 gig) and overclock speeds of up to 4866 MHz For storage, you have the options of 1 NVMe and 4 sata drives, or you can run two NVME and 2 Sata drives (installing a second NVMe drive typically disables two sata ports. The only real problem I have is mine came with a USB port with a short in it causing my power to instantly power off any time anything is plugged into the port. (I know this is a defect instead of design flaw because mine seems to be the only one with this problem and it did this from day one) Over all, very happy though and SUCH an upgrade from my last motherboard!
