Supports AMD Ryzen™ 5000 & 3000 Series desktop processors (not compatible with AMD Ryzen™ 5 3400G & Ryzen™ 3 3200G) and AMD Ryzen™ 4000 G-Series desktop processors Across the bottom of the boards are several headers and a switch. These are all listed from left to right below. I have to admit however, if your option 5 out of the 4 was a real world choice here, I'd take that X370 over a B550 any day.)

In the middle, there are a total of three PCIe slots. One is full-length, CPU-fed x16 lanes and uses slot reinforcement while the other two are x1 size with bandwidth fed from the chipset. Since there is only one full-length slot, multi-GPU support isn’t even a consideration here.

The MSI B550M PRO-VDH WIFI is a reliable motherboard that is crafted with premium materials, providing durability over time. With its compact size, it can fit into smaller PC setups where space is limited. It also has a sleek design that can complement any PC build. I have to admit however, if your option 5 out of the 4 was a real world choice here, I'd take that X370 over a B550 any day.)Why so serious? I only put it there because nobody had posted anything and it's funny (because of option 5 out of 4). Of course it doesn't work unless someone already has the board. It's one of those "D'UH" posts that just takes up space. It also informs people that it is an option. One could say "everyone knows that" and I would've agreed once upon a time but then someone asked me for a source when I mentioned that Zotac is just Sapphire in disguise (and I thought everyone knew that).

In terms of functionality, the MSI B550M PRO-VDH WIFI has all the necessary features needed for a smooth PC experience. It has a decent number of memory slots that enable upgrades and can support multiple graphics cards. The motherboard is well-suited for gamers and content creators who need a high-performance system. With its AMD B550 chipset, users can enjoy faster data transfer speeds, which is a plus for data-intensive tasks.USB 3.2 Gen 1 5Gbps ports (1 Type-C internal connector, and 2 ports are available through the internal USB 3.2 Gen 1 5Gbps connector)

I have to give you props for creativity, but when it comes to those of us that don't have a baller AM4 board (or any AM4 board) and are vaguely interested in throwing a box together on the cheap, recommending option 5 out of 4 legit choices might as well be saying to divide by 0.

To the right on top is the first (of five) four-pin fan headers. All ports support both PWM and DC modes for speed adjustment via the BIOS. Outputs on the System fan headers are 1A/12W, 2A/12W on the CPU header, and 3A/36W on the PUMP_FAN1 header. There’s plenty of power available here to connect fans and pumps. Finally, to the right of the small pushpin-attached chipset heatsink are four SATA3 6Gbps ports, oriented vertically. These ports support RAID0, 1 and 10 modes. Zooming in on the top half of the board, we’re greeted by a lot of exposed PCB. There is a small heatsink attached via pushpins to the left VRM bank, while the top VRMs are left bare. I’m not a big fan of pushpin-attached heatsinks, as they don’t tend to hold as well as those that are screwed on. Power comes from a single 8-pin EPS connector, located next to the top VRM bank.

Sliding down to the bottom half of the board, on the left side is a fully exposed audio section showing off the mid-range Realtek ALC892 codec, along with four Chemicon brand audio caps. This isn’t the best audio solution we’ve seen, but again, par for the course on the budget end and sufficient for most users. Supports DDR4 2667/ 2800 /2933 /3000 /3066 /3200 /3466 /3600/ 3733 /3866 /4000 /4133 /4266 /4400+ MHz by A-XMP OC MODE PCIe 4.0 x4 / SATA + PCIe (up to 80mm), (1) PCIe 3.0 x4 / PCIe Only (up to 80mm), *NVMe supports RAID0, 1 Premium Thermal Solution: 7W/mK pad, additional choke thermal pad and M.2 Shield Frozr are built for high performance system and non-stop works

Price comparison

Intel® Dual Band Wireless-AC 3168 Supports Wi-Fi 802.11 a/b/g/n/ac, dual band (2.4GHz, 5GHz) up to 433 Mbps speed. It doesn't have PCI-Express v4.0 but that's irrelevant except for high-speed NVMe drives at this point. Superior power delivery when compared to the A-series and B-series boards. Platform is mature and stable. Far more nice features on an X-series board like more USB, Intel Gigabit LAN and the audio is Realtek ALC892 with 7.1 channels.
