MSI MPG B550I Gaming Edge Wifi

As it currently stands, MSI has unveiled a single mini-ITX model to cater to small form factor users and enthusiasts, the MSI MPG B550I Gaming Edge Wifi. Following a similar design to the ATX sized B550 Gaming Edge Wifi, the smaller mini-ITX version is packed with features including an 8-layer PCB, a full-length PCIe 4.0 x16 slot, two M.2 slots, with a Realtek 2.5 GbE Ethernet controller and Wi-Fi 6 interface pairing.

The MSI MPG B550I Gaming Edge Wifi is using an all-black theme throughout with subtle grey accents on the rear panel cover and heatsinks. The bulk of the feature set hangs around B550's PCIe 4.0 support including one full-length PCIe 4.0 x16 slot, one PCIe 4.0 x4 M.2 slot, and a second PCIe 3.0 x4 M.2 slot. Although B550 models have generally ditched the actively cooled chipset heatsinks, the B550I Gaming Edge Wifi includes a cooling fan in what looks to be an amalgamation between the chipset heatsink and the PCIe 4.0 x4 M.2 slot. For conventional SATA drives, MSI includes four straight-angled SATA ports with support for RAID 0, 1, and 10 arrays. While mini-ITX models have been favored for enthusiast memory overclockers due to shorter memory traces to the CPU, the B550I Gaming Edge Wifi supports up to DDR4-4600 officially which is much lower than other MSI MPG B550 models. Users can install up to 64 GB across two available memory slots.

The rear panel includes a varied selection of IO including a single USB 3.2 G2 Type-C, two USB 3.2 G1 Type-A, and two USB 2.0 ports. MSI includes a single HDMI 2.1 video output for users looking to opt for a Ryzen based APU, while a PS/2 keyboard and mouse combination port allows the use of legacy peripherals. For networking, there is a Realtek RTL8125B 2.5 GbE Ethernet controller, with an Intel AX200 Wi-Fi 6 interface which also allows the use of BT 5.0 devices. Rounding off the rear panel is a small BIOS Flashback button, and five 3.5 mm audio jacks and a single S/PDIF optical output which is powered by a Realtek ALC1200 HD audio codec.

The MSI MPG B550I Gaming Edge Wifi is the only mini-ITX model at launch from the company, and it is seen as a direct replacement to the B450I Gaming Plus AC. While it offers a better controller set and includes official support for PCIe 4.0 via the full-length PCIe 4.0 x16 slot and PCIe 4.0 x4 M.2 slot, it comes at the much more premium price of $200. With two USB 3.2 G2 slots including a Type-A and Type-C pairing, and a Realtek RTL8125B 2.5 G Ethernet controller, with Wi-Fi 6 and two M.2 slots, it looks a competitive model in the mid-range mini-ITX market space.

    Right now, it seems more like B for Backordered. They may be priced a bit high, but the demand still seems to be there.

    This is a great article but it needs a follow up with a table for every motherboard explaining how they use the PCIe lanes in conjunction with M2 and SATA slots. It seems that motherboard makers are totally f up(sorry for the expression) the more reasonably priced models in that area.

    Does anyone know if the boards that have the Intel i225-V are shipping with the fixed hardware (v2)?

    Wow, another broken Intel NIC? I wish motherboards would stop using Intel NICs.
  • mooninite - Tuesday, June 16, 2020 - link

    After Googling it looks like v2 is not fixed either... a v3 is coming out. Time to buy Realtek.

    Which is hilarious - I remember when Realtek was the worst when it came to NICs, and Intel/3Com was the standard. :)

    Yes, indeed...;) My x570 Master has an Intel gigabit & a realtek 2.5gb. It's amusing because my interface is an EWAN that tops out at 1Gb, but I thought I'd try the realtek just to see and then I forgot about it...;)...Seems every bit as stable as the Intel--still on it, lol...;) Six of one, half-dozen of another.

    Thanks Ian and Gavin! One question, related to a likely use case for B550 mini ITX or mATX Boards: is it true that AMD will, at least initially, limit Ryzen 4000 APUs to OEMs? If that is so, I am definitely not interested in a B550 board in those form factors, and I don't think I am alone here. An answer is appreciated - thanks!

    I'm just here for the Next mini-ITX boards. I'm liking the Aorus Pro AX quite a bit.
