Get your next build off on the right foot with the MSI PRO B650M-A WIFI AM5 Micro-ATX Motherboard. Sporting a smaller form factor, the PRO B650M-A WIFI offers robust connectivity without compromising performance, making this ideal for new and seasoned builders alike.

With an AM5 socket, you can support a wide range of AMD Ryzen 7000 Series processors. Four dual-channel DDR5 RAM slots allow you to install up to 128GB of memory so you can scale your multitasking performance to your liking. Four SATA and two M.2 interfaces allow you to create an array of storage drives for your games, media, and other important applications. Install graphics and utility cards with one PCIe 4.0 x16, one PCIe 4.0 x16 (in x4 mode), and one PCIe 3.0 x1 slot. The back panel provides you with ample connectivity options, giving you four USB-A 3.2 Gen 1 and four USB-A 3.2 Gen 2 ports, giving you data transfer speeds up to 5 and 10 Gb/s, respectively, suitable for a wide range of peripherals such as your keyboard and mouse. Bluetooth 5.2 technology provides support for wireless devices such as headphones and controllers. When combined with Ryzen processors with integrated graphics, the DisplayPort and HDMI video outputs can provide you with enhanced visual capabilities suitable for light workloads and troubleshooting. Connect to your network via Wi-Fi 6E (802.11ax) technology or use the integrated 2.5 Gigabit Ethernet port for a reliable wired connection.

DIY Friendly
The PRO B650M-A WIFI includes a variety of built-in functions that enable an easy installation ideal for both new and seasoned builders. PCI-E Steel Armor slot provides extra rigidity to the expansion slot by adding metal plating and extra anchor points. EZ M.2 Clips make installation of solid-state drives easier and quicker. EZ DEBUG LED, EZ LED Control, and Flash BIOS Button streamline your troubleshooting process in the event of a failure.
Thermal Enhancements
The PRO B650-A WIFI includes many thermal enhancements that allow you to fully utilize the power of your components without worry of throttling. Extended heat sink design along the back panel, MOSFET Baseplate and K7 thermal pad, M.2 Shield Frozr, and extra choke pad all ensure the motherboard remains cool even under heavy loads.
Performance Boosting Technologies
Integrated software- and hardware-based technologies are integrated into the fabric of the PRO B650-A WIFI design. Not only is electrical load managed throughout the 2 ounce copper thickened PCB, but efficiency is optimized with Dual CPU Power design. Core Boost and Memory Boost technologies promote greater communications between the processor and memory modules for better performance.

MSI PRO B650M-A WIFI Reviews

256GB of RAM with a consumer CPU!

By Daniel
Rated 4 out of 5
Date: 2025-03-11

MSI was one of the first vendors to officially support 256GB on their AM5 motherboards so I thought they were a safe pick for a RAM heavy machine and they didn't disappoint. I did need to update the BIOS to take 4x 64GB DIMMs, but that took less than 10 minutes. The motherboard has a flash bios button, so I presume you can even update the BIOS if your CPU is too new for the shipped BIOS. I also appreciate that there are two additional PCIe slots beyond the base x16 for your GPU. The fan curve control doesn't have the best interface, but it's perfectly workable. This WiFi motherboard also has bluetooth, which was the reason I selected this over the non-WiFi variant. I dislike that this motherboard doesn't have a solid back IO panel. Instead it depends on a tension mount like a budget motherboard. The panel is also silver and not black like the motherboard itself. Definitely not the most stylish choice.

Great Board for the Price

I have built a good 40 computers with this board. It is a solid board and has given me very little problem. This board will work for just about anything. I use them mostly in my workstation builds but they work fine in a low cost Gamer build as well.
