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.

    Looks like some nice mATX versions this round, nice!

    I was hoping to see a $75-$90 board.

    Fortunately, this component is a unique motherboard among B550 and well worth reading up on [add link].
    Needs to be edited.

    There's a noise sensor which can adjust fan speed for maximum quietness with good thermals. Saw it on the KitGuruTech video. The noise sensor isn't there to spy on you though.

    The quality of the editing here is shit tier. Seriously, just run the articles through Grammarly before publication. It's free and it spots plenty of errors.

    Sadly none of the mITX boards have more than 6 external USB ports. My old ASUS mITX has 8! And in really small mITX cases you can't add a bracket with more USB, because the two brackets are already used by the gfx card. Guess I have to wait for an enthusiast mITX board )-:

    Or, just maybe, get a usb dongle with 4 ports?

    That is disappointing. The number of USB devices people need to plug in can't be dropping, surely? I know I've got more now then even a year ago.

    Are they really going up? I have 2 USB devices plugged in to my system - a keyboard and a mouse. I occasionally plug a USB stick in one of the front ports to transfer files. My phone and tablet sync over wifi, they don't get plugged in. I have a charger behind my desk and a cable to charge them. My printer is on the network.
    The one place I DO need lots of USB ports is also the place where I have a small cube case machine, with no discreete GPU, because it doesn;t need one. On that one I added a USB PCI card to get enough ports. In addition to the keyboard and mouse, that machine is on my workbench where it connects to several electronic test instruments and I have multiple cabled for programming microcontrollers. I also have a USB microscope for board inspection. And then I have 3 more USB devices connected for my other hobby that shares the bench. Plus a front port kept free for USB sticks.
    So the use case I have for more USB has the PCI slots open to add expansion cards, the use case where I have a discrete GPU eating up the slot space doesn't need an excess of USB ports.

    I use 3 USB 3.0 ports just for my Oculus Rift
