B450 TOMAHAWK MAX (Socket AM4) DDR4 ATX Motherboard

The B450 chipset forms the centrepiece of the MSI B450 Tomahawk motherboard and has been specially developed and optimised for 2000- series (Pinnacle Ridge) Ryzen CPUs and now with 3000 Series support. B450 motherboards support all features of 2nd gen Ryzen processors, such as the AMD's new XFR2 overclocking. Additionally, the motherboards support up to 64 GB of RAM with a guaranteed clock frequency of 2.933 MHz. Overclocking to higher frequencies is also an option, although the increase will depend on the motherboard.

The Features of the MSI B450 Tomahawk at a Glance:

  • 1x PCIe 3.0 x16 (x16) for high-end graphics cards
  • 2x USB 3.1 (1x Type C, 1x Type A) / 4x USB 3.0 / 6x USB 2.0
  • 1x M.2 slot PCIe 3.0 x4 (22110)/ 6x SATA 6G
  • DDR4-RAM up to 3.466 MHz via OC
  • 1x HDMI / 1x DVI-D / 1x VGA

The Features of the MSI B450 Tomahawk in Detail:

The MSI B450 Tomahawk ATX motherboard comes with one PCI-Express 3.0 slot with full x16 connectivity for graphics cards as well as a PCI-Express 2.0 x16 slot with x4. For additional expansion cards, the board offers three PCIe x1 slots. The four RAM slots support up to 64 GB DDR4-RAM with a clock frequency of up to 2.933 MHz and can be clocked up to 3.466 MHz via overclocking.

An M.2-slots with PCIe connectivity is available thanks to it being an AM4-based motherboard. M.2 SSDs with the advanced NVM-Express protocol (NVMe) and that are connected via four PCI-Express 3.0 lanes are up to eight times as fast as SATA 6G hard drives and support data transfer rates of up to 32 Gbit/s.

The MSI B450 Tomahawk has an I/O panel with one USB 3.1 connection with Type C connector and a USB 3.1 Type A port. The USB Type C port allows devices to be inserted in either orientation and is extremely slim. USB 3.1 Gen 2 ports enable maximum speeds of up to 10 Gbit/s per port and USB ports that use this standard generally support smartphones and tablets with quick charging. For CPUs with integrated graphics such as AMD's Raven Ridge, the board offers one HDMI- and one DVI-D port.

In terms of special features offered by the MSI B450 Tomahawk it includes red LED lighting on the chipset cooler and the right side of the motherboard. The LEDs can be connected together with other LEDs using the RGB headers and controlled via MSI's Mystic Light software. The motherboard comes with two headers for static RGB lighting elements.

Great board for a great price

Great board for a great price. Simple instructions for a first time builder.

Nigel smith 2020-02-02

The best motherboard I have ever owned!

This is my first MSI product since I had to upgrade my PC just recently and all I can say this was the best choice possible, it looks pristine and the build quality is excelent! Easy to install everything the bios has both EZ and Advanced mode if you aren't that familiar with those things. My Ryzen 3600 runs perfectly and my RAM memory running at 3200 with just a simple button press nothing else! If you are looking to get a new board buy this cause for that price it's a steal compared to what quality you get.

Tibor Kovács 2020-01-08

Top MB for the price

Bought this mb for a 3600X after several forums addicted it as the best b450 card. What can I say? It is absolutely right! Absolutely recommended!

Andrea Baessato 2019-12-06

Great value for money!

When I first received this motherboard it was part of a build I had designed to upgrade from a 9 year old 2nd gen intel system to a Ryzen build. All I can say is what an incredible motherboard! The design of the board is incredible. It looks amazing and the build quality of it feels like I got more than what I paid for.
Ultimately I chose the MSI B450 Tomahawk Max because I wanted a motherboard that had RGB to complement the rest of my build and also had decent software to control the RGB in one solution.
To say that the board delivered upon my expectations is a no brainer. It was simple to fit into the case I have. All ports are evenly spaced apart giving a great layout and even the connectors on the board are self-explanatory.
Ultimately this is a great board and I am extremely happy with my choice. The aesthetics, build, layout and features feel like they are worth more than what I paid for. You can tell the MSI put a lot of thought into this board when designing. Will happily buy MSI products again.

Lush motherboard

I decided to upgrade my gaming PC and I switched from Intel to AMD...couldn't be happier! Super simple easy and smooth instalation process. Tomahawk has solid build, all ports you might ever need, looks fantastic and costs under £100 - absoloute dream. I've put Ryzen 5 - 2600x in it and booted right away without any need of setting things up. Overall - another excelent product from MSI

Great Budget Board!

I think this is an excellent board when paired with AMD processors and graphics cards. It is top quality and is accomodating to any PC casing. I personally bought this to go along with an AMD Ryzen 7 2700X octacore and an AMD RX590 8GB GPU.

Ryzen 7 3700x build

Purchased this board for a new replacement PC build using the Ryzen 7 3700x along with a Zotak RTX 2080 AMP Extreme.

The boards look look great and are of excellent built quality.

I went for the B450 as it's more than adequate for the job with a multi-core CPU and the 3200Mhz RAM I installed.

There are plenty of aarticles that cover the boards spec's

However here are my personal Pros and Cons

Very reasonably priced
On-board USB-C
EZ-Flash (USB flashing without the need for CPU/GPU inserted.
Cool looking BIOS with plenty of features
The larger BIOS retaining the graphical interface when upgrading (some revert back to the text type view)
Cool and Quiet.
M.2 support

Better RGB Support ( has Mystic Light but would have preffered if it was able to control the Corsair natively)
USB Power on (keyboard power up)

This is a great board, and works perfectly, thank you
