MSI B450M Mortar and
MSI B450M Mortar Titanium

Like the MSI B450M Bazooka boards, the MSI B450M Mortar and the B450M Mortar Titanium are a part of the MSI Arsenal Gaming collection with the focus being on offering gamers a lower cost alternative and starting point for an e-Sports based gaming system. Unlike the B450M Bazooka and Bazooka Plus models, the only differences between both the B450M Mortar models come in the aesthetics; the B450M Mortar Titanium has a classy silvery PCB and pairing of heatsinks which gives it a unique look. Both boards also have RGB LEDs implemented underneath right-hand side of the board with the option add an additional two 5050 RGB LED strips.

The B450M Mortar/Mortar Titanium are both microATX form factor, with support for AMD 2-way CrossFire multi-graphics card configurations. The PCIe on the boards consist of a full-length PCIe 3.0 x16 slot with MSI’s Steel Armor slot reinforcement, and a second full-length PCIe 2.0 x4 slot; also included is two PCIe 2.0 x1 slots. Storage wise both models have four SATA right angled ports and two M.2 slots with both slots supporting M.2 2280 (22 x 80 mm) drives, but only one of the slots offering full PCIe 3.0 x4 support. The second slot has support for PCIe 2.0 x4, with both M.2 slots supporting SATA drives too.

Power delivery wise, the B450 Mortar/Mortar Titanium looks to have seven phases running in a 4+3 configuration. Power to the CPU is provided by an 8-pin ATX 12 V power input while the motherboard takes power from a regular 24-pin ATX connector.

Up to DDR4-3466 memory is supported with a total of four memory slots offering a maximum system memory capacity of up to 64 GB. The boards also have a total of four 4-pin fan connectors with one being dedicated to the CPU and the rest set aside as system fan headers.

Both the B450M Mortar and B450M Mortar Titanium share identical rear panels with a two USB 3.1 10 Gbps ports (Type-A and Type-C), four USB 3.1 5 Gbps Type-A ports and two USB 2.0 ports. A pairing of video outputs with support for the Ryzen and Zen based APUs include an HDMI 1.4 port and a DisplayPort. A BIOS Flashback+ button is also included, with a PS/2 combo port, five 3.5mm audio jacks and a S/PDIF optical output and single RJ45 LAN port.

The B450M Mortar offers decent quality controllers and it’s expected that these will cost slightly more than the other microATX B450 Bazooka/Bazooka Plus pairing, but with support for 2-way CrossFire multi-graphics configurations, the B450M Mortar and B450M Mortar Titanium could comfortably be the foundations of a powerful microATX gaming system.

    Signed up to point that out. Needs to be fixed. It’s the only ITX board supporting 2x which sets it’s apart form the competition

    Glad to see more options in the mATX range with two M.2 slots, not just from AsRock this time around. My next rig will either be based on the AsRock B450M Pro4 or one of the MSI B450M Mortar boards. Will wait for actual VRM setup and overclocking results / general tests to see which one will be it. I had motherboards from both manufacturers and was pleased with both. MSI has the advantage of offering PCIe M.2 options for both slots as well as SATA. One question regarding that: if I install a 3.0 PCIe x2 M.2 SSD into a 2.0 PCIe x4 slot, what will be the speed ramifications? Can it only use 2.0 PCIe x2 or can it use the full x4, thus being similar in speed to a native 3.0 PCIe x2 setup? :) Still waiting on mATX x470 mainboards.

    .3.0 x 2 is the same speed as 2.0 x 4

    Except that a 3.0 x2 drive is almost certainly x2 because it only has 2 PCIe lanes (cutting down on them is one of the ways the cheaper drives pinch pennies), which means it will be connected at 2.0 x2; at that point you might as well just use a SATA drive and save a bit more money.

    Thanks for providing an answer to my actual question. :)
  • AdrianB1 - Tuesday, July 31, 2018 - link

    You will get a 2 lane PCIe 2.0 connection, that means 1 GB/s. This is 1/4 of a PCIe 3.0 4-lane usual NVME drive, but real life you may get closer to 80% of the performance.

    Thanks!

    Finally some budget boards with solid VRMs.
  • skpetic - Tuesday, July 31, 2018 - link

    There are some seriously shady stuff going on with VRMS om X470 og B450. Check out Buildzoid on youtube. Asus B450 STRIX ITX board is single phase for SoC. Several of the Gigabyte B450 and X470 boards in reality have half the advertised amount of phases or are using doublers:

    hahaha... no

    Asus with the absolute trash tier VRM heatsinks
    AsRock with fake phases
    Gigabyte with fake phases and trash VRM heatsinks
    MSI with no Vcore offset
