MSI B450 Tomahawk

The MSI B450M Tomahawk is a direct successor to the B350 Tomahawk we previously reviewed, but with a few visual tweaks and the introduction of RGB LED lighting to the mix to give it a more ‘popular’ reach to those looking to customize their system to fit their components and mood. The B450 Tomahawk sports the same Realtek ALC892 audio codec and the same Realtek 8111H Gigabit LAN controller as the B350 model, and on paper, look very similar.

The main differences come through a new PCIe layout consisting of a full-length PCIe 3.0 x16 slot featuring MSI Steel Armor, with a second full-length slot running at PCIe 2.0 x4 and a trio of PCIe 2.0 x1 ports; these replace the legacy PCI slots featured on the previous B350 Tomahawk. One of the advantages of the B450 chipset over B350 is the memory speeds supported, more specifically due to the refined firmware possessed by the B450 Tomahawk, which allows support for DDR4-3466 with a total of 64 GB of system memory supported over the four available slots. The use of both ECC and non-ECC memory is permitted, although the ECC memory will run in non-ECC mode. The main visual difference is the B450 comes with new but svelte looking heatsinks and the power delivery heatsink has the MSI Arsenal Gaming logo to signify the entry-level gaming range this board represents. MSI also seem to have kept the same 6-phase power delivery running in the same 4+2 configuration as the previous B350 Tomahawk.

Storage wise, the B450 Tomahawk has a total of six SATA ports with four featuring right-angled connectors and two having a straight angled design; RAID 0, 1 and 10 arrays are supported. A Single M.2 slot capable of supporting PCIe 3.0 x4 and SATA drives up to a size of M.2 22110 (22 x 110 mm).

On the rear panel, the B450 Tomahawk includes a BIOS Flashback+ button with two USB 3.1 5 Gbps Type-A ports, two USB 2.0 ports and a USB 3.1 10 Gbps Type-A and Type-C port. Also included is a PS/2 keyboard and mouse combo port, six 3.5mm audio jacks powered by a Realtek ALC892 audio codec, a single LAN port controlled by a Realtek 8111H Gigabit networking chip, and two video outputs consisting of an HDMI 1.4 port and a DVI-D port.

While the B450 Tomahawk offers improved memory speeds, classier heatsinks and a small customizable RGB LED strip in the top right corner of the board, the price is likely to reflect this with a touted price of $109.99 at launch; around $20 more than the B350 Tomahawk. Whether or not the new refreshed Tomahawk matches specification and visual aspirations of users, the extra integrated RGB lighting and new style MSI Arsenal Gaming heatsinks on the B450 chipset come at a more expensive premium.

    The ASRock microATX B450M Pro4 has a total of four SATA ports not the six as wrongly posted on the final page table for choosing the right B450 Motherboard.

    Yet not a single high-end X470 mATX motherboard !!

    WHY ON EARTH DO THEY KEEP MAKING AMD BOARDS WITHOUT DISPLAYPORT?

    FreeSync is a game changer for the Ryzen APUs, and very few of the inexpensive adaptive sync displays support FreeSync over HDMI.

    Gavin Bonshor's otherwise excellant page on choosing the right B450 motherboard doesn't include a list of boards that support DisplayPort. Unless I've missed some, there are eight:

    ASRock B450 Gaming K4
    ASRock B450 Gaming ITX/ac
    ASRock B450 Pro4
    ASUS ROG Strix B450-F Gaming
    MSI B450I Gaming Plus AC
    MSI B450M Mortar
    MSI B450M Mortar Titanium
    MSI B450-A Pro

    I once had a motherboard with a Realtek network controller and got so sick of it randomly connecting at 10 mb/sec that I vowed I would never buy another Realtech network controller. That leaves only one B450 option:

    ASUS ROG Strix B450-F Gaming

    There is also the MSI B450 Carbon AC that in theory is better as it has better VRM and wireless LAN. It is also a bit cheaper in the stores in my area.
  • DMCbr - Sunday, August 5, 2018 - link

    I think MSI totally won this time, with the PRO Carbon AC board: best sound, best lan, wifi, 5+2 VRM phases, good heat-sinks...

    Great, really great ... but still can't buy outside of USA 13" laptop with Mobile Ryzen APU except extremely expensive not so well designed Lenovo 720S. What is the reason?
  • Djoie123 - Tuesday, August 14, 2018 - link

    I think that B450 gaming plus have 4+3 vrm phase design, on their site they said it's 7 phase power design
