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.

    I've read elsewhere that Zen1 processors supposedly had a 128 Mb address limit for UEFI firmware. It sounds suspect, but looking back at early AM4 boards, I don't recall any with either 256 Mb chips or striped 128 Mb chips, so maybe it wasn't simply due to the significant jump in price for 256 Mb chips over 128 Mb ones.

    Likewise, looking to replace my aging 7 year old HTPC with a mATX B550 and a Ryzen 4700G but radio silence from AMD on releasing compatiable APU's for the B550's, We now have the long overdue Budget motherboards but no APU's. Dissapointed.

    I understand the frustration however if your buying a Budget Board then surely a budget CPU is the best fit, also new APUs are inbound according to all the rumours, meanwhile your older APU will fit just fine I believe, I expect the new APUs will have Navi cores as per the Xbox and PS5 but of course they probably cannot be released until the new Navi cards and consoles are out, think about it though what a sea chamge folks are now waiting eagerly for a new release from AMD because they know it will kick ass not close the gap to Intel, its a good time to be a customer!

    Older APUs aren't supported on B550

    I think you forgot something... :-)

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

    Interesting that the GIGABYTE B550 Vision D board's Type-C ports don't have the Thunderbolt logo next to them. I wonder if Intel won't all the logo to be use on AMD systems.

    "Although on paper, there isn't much difference between B450 and B550 with slightly more SATA available due to the removable of eSATA support, both remain PCIe 3.0 bound."

    The B450 only had PCIe 2.0 lanes. Huge difference from the B550 IMO
  • Lucky Stripes 99 - Tuesday, June 16, 2020 - link

    Agreed. That's going to make a huge difference for boards with secondary or tertiary M.2 or U.2 ports that hangs off the chipset. That goes double if they only get 2 PCIe lanes instead of the full 4.
  • a5cent - Friday, June 19, 2020 - link

    Yup, exactly what I thought.

    Equally "BIG" is that B550 finally has more PCIe lanes, so adding more NVMe drives doesn't require downgrading other ports like it always did on B450.

    B450 was a firmware upgrade for the budget B350 chipset. B550 is the first time this tier of AMD chipset doesn't suck.
