MSI MAG B550M Mortar & B550M Mortar Wifi

The MSI B550M Mortar Wifi and B550M Mortar are MSI’s only micro-ATX models currently available at launch and represents the Arsenal series which is MSI’s entry-level gaming range. Both models are identical in terms of features and aesthetics, aside from the Wifi version which comes with a Wi-Fi 6 interface. Some of the pairings other features include two M.2 slots, a Realtek ALC1200 HD audio codec, and a Realtek 2.5 GbE Ethernet controller.

Focusing on the design, the MSI MAG B550M Mortar has a very elegant contrasting design, with striking silver heatsinks on a black and grey patterned PCB. The Mortar includes two full-length PCIe slots with a top slot which operates at PCIe 4.0 x16, a second slot is locked to PCIe 3.0 x4, as well as two PCIe 3.0 x1 slots. The storage capabilities include six SATA ports with support for RAID 0, 1, and 10 arrays, with a pair of M.2 slots. The top M.2 slot operates at PCIe 4.0 x4, while the bottom slot operates at just PCIe 3.0 x4. Users can install up to 128 GB of DDR4 across four memory slots, with speeds of up to DDR4-4400 officially supported.

On the rear panel is a pair of USB 3.2 G2 ports including a Type-A and Type-C, with two USB 3.2 G1 Type-A and two USB 2.0 ports. A Realtek RTL8125B 2.5 G Ethernet port takes care of the audio, while the B550M Mortar Wifi model includes an Intel AX200 Wi-Fi 6 interface with support for BT 5.0 devices. The boards five 3.5 mm audio jacks and S/PDIF optical output are controlled by a Realtek ALC1200 HD audio codec, and the pairing also includes an HDMI video output, a BIOS Flashback button, and a PS/2 keyboard and mouse combo port.

The MSI MAG B550M Mortar Wifi has an MSRP of $170, while the non-Wi-Fi version costs $10 cheaper at $160. On paper, the Mortar is similar to the B550 Tomahawk without the additional Realtek Gigabit Ethernet port, and visually it looks like a stylish offering. The B550 Tomahawk does officially feature better memory support, and although MSI aims at a higher with its MAG series in comparison to its B450 models, the Mortar Wifi for $170 looks like a solid alternative.

    Same here. Both DVI and DP can be converted to VGA using an inexpensive passive dongle. I'd much rather see either of those ports over VGA.

    DVI-I can be converted easily. DVI-D (which most of the modern boards have) need a more complex adapter.

    I believe you will find Asus use S1220A so not S1200A , it's custom version of ALC1220, when you go by Asus website for their B550 boards.

    There seems to be no mentions of Thunderbolt 3 header that apparently comes with this motherboard according to Asia’s own website:
    https://edgeup.asus.com/2020/b550-motherboard-guid...

    Does anyone know how or what this connects to on a mITX motherboard?
  • blakflag - Monday, June 22, 2020 - link

    Does "USB 3.2 G2 Type-C" imply Thunderbolt 3 support?

    And here it is a couple of weeks after the 'release' and there are no boards (well, no mATX versions) to buy...unless you want to deal with the scalpers on NewEgg asking $25 to 35 over the regular price - oh, and BTW, they will ship/deliver in mid-July - AND I see no reviews or comparisons other than manufacturers' sites advertising for the B550 boards. The few articles I see are all based on the pre-release data and not from actual delivered, installed and tested MBs. Poor AMD hardware release, as far as I am concerned.

    Oh, and the listing is incomplete with a couple of manufacturer-advertised versions od mATX boards not listed in this article.
