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.

    Gavin, you made a table that shows B350 and A320 don't support PB2 and XFR2. This is incorrect. Raven Ridge (2400G, 2200G, 2X00U) work without a problem on these boards. Yes, Raven Ridge has PB2 and XFR2 from day one. AMD advertised it when they launched RR last year.

    It's not natively enabled from launch - it requires a BIOS update which not all vendors on all boards have provided. The CPUs work sure, but not all features of the CPUs will work in all products. Reply

    PB2 and XFR work on A320 as well. Reply

    If you buy the boards directly from there amazon store or on there website they should be Stock updated.

    Please fix your charts. PCIe should be 3.0 not 2.0 Reply
  • Ian Cutress - Tuesday, July 31, 2018 - link

    The Chipset supports PCIe 2.0 lanes. PCIe 3.0 lanes come from the CPU. Reply

    StoreMI can work on 300-series motherboards but comes with an additional fee (I don't think it's BIOS dependent).

    The systems support 10 GbE, if you buy the cards. Yes it's picking hairs, but we're speaking native support. Reply

    What does 10GbE have to do with StoreMI?! Reply
  • Ian Cutress - Tuesday, July 31, 2018 - link

    10GbE has nothing to do with StoreMI. I was using it as an example of something that the system supports if you buy it. Like StoreMI. Reply
