Biostar has launched its latest AMD B550-based board, the B550M-Silver. Aimed at gamers looking to use AMD's latest Ryzen 5000 processors, it brings a host of premium features to the micro-ATX form factor with USB 3.2 G2 connectivity, a Realtek 2.5 Gb Ethernet controller, Wi-Fi 6, and PCIe 4.0 support. 

Over the last couple of years, premium AMD micro-ATX boards have been few and far between, with the majority of vendors opting to release their micro-ATX models on the more budget-friendly chipsets such as AMD's A520. The micro-ATX form factor typically offers a convenient compromise, with more expansion slot support than the smaller mini-ITX form factor, but without the overall footprint of ATX. Based on the AMD B550 chipset, the Biostar B550M-Silver offers out of the box support for Ryzen 5000 processors, with support for Ryzen 3000 chips too.

Focusing on the design, the Biostar B550M-Silver uses a wave of silver heatsinks, including a large rear panel cover, which doubles up as one section of the power delivery heatsink. It includes no integrated RGB LED lighting nor any RGB headers, which is either quite strange or a welcome relief given how common RGB is these days in boards aimed at gamers.

The Biostar B550M-Silver includes dual PCIe M.2 slots, with the top slot capable of supporting up to PCIe 4.0 x4 2280 M.2 drives, while the second slot includes support for PCIe 3.0 x4; both of these slots can accommodate SATA based SSDs. For SATA, Biostar includes six SATA ports, with two straight-angled and four right-angled ports, with support for RAID 0, 1, 10 arrays. There are four memory slots with support for DDR4-4933, with a maximum capacity of up to 128 GB. 

There are two full-length slots at PCIe support, including a PCIe 4.0 x16 and a PCIe 3.0 x4 slot, with a PCIe 3.0 x1 slot sandwiched in between. Located under the full-length PCIe 4.0 x16 slot is a Key-E 2230 slot, although the board already includes an integrated wireless module.

On the rear panel is a variety of connections, including a single USB 3.2 G2 Type-A, one USB 3.2 G2 Type-C, four USB 3.2 G1 Type-A, and two USB 2.0 ports. There is a trio of video outputs including an HDMI, DisplayPort, and DVI-D for use with AMD's 3rd gen APUs, while the board's three 3.5 mm audio jacks are powered by an older Realtek ALC1150 HD audio codec. A PS/2 keyboard and mouse combo port sits above the USB 2.0 ports, while a single RJ45 port is powered by a Realtek RTL8125B 2.5 GbE controller, while Biostar is using an unspecified wireless interface with support for Wi-Fi 6. 

At present, we don't know when the Biostar B550M-Silver will hit retail shelves, nor do we have information in regards to the pricing.

Update - Biostar has informed us that the B550M-Silver has an MSRP of $119, which represents fantastic value with 2.5 GbE and Wi-Fi 6 networking.

    Do you have some examples? I was looking for one that supported the older APUs.

    I'm happy to see more decent mATX board this generation. It was always the achilles heel of AMD, there was not a single good mATX AM3+ board and one whole AM3 board. With dual GPU being forever dead now, mATX is the way to go if you need more then just a GPU

    True. The overall specs for this board are good. The real I/O is odd (though I actually appreciate the PS/2 port) but the 1150 audio codec and 2.5G NIC are fantastic at this price and really should be the bare minimum for any board these days.

    "fantastic at this price"
    What is the price?

    I'm pretty sure that the mini-pciE connector on the board is for the "unspecified wireless interface," it doesn't actually have a wifi chipset onboard.

    Look at the antenna leads right by that socket, those presumably just run to the back panel's larger connectors.

    If they're going to do it that way, major disappointment that they didn't install 3 or 4x leads so you could take advantage of a 3:3 or 4:4 card later (even if they were too cheap to ship the board with more than 2:2).

    I’d prefer more DTX board choice

    WiFi 6 support.... buy M.2 2240 card and install it. Fantastic value! Why not WiFi 7 or 8?
    Other vendors integrate WiFi cards, not only antenna sockets.
