The MSI MAG B550 is an excellent gaming motherboard that works with all current AMD processors. It has an eye-catching design, a variety of features, and it comes at a great price. If you’re looking for a new gaming motherboard or an upgrade to your computer that’s already in use, we highly recommend checking out MSI MAG B550 Tomahawk. You won’t be disappointed! This motherboard also supports 7th generation A-series/Athlon processors. Just make sure to update your BIOS before installing any new hardware so you can take advantage of its full potential.

And don’t forget about RAM compatibility: although MSI says these motherboards support DDR4 RAM up to 3200MHz, they will only reach those speeds if they are paired with a Ryzen CPU. The highest speed RAM that works well with Ryzen CPUs is DDR4 3000MHz memory modules (see below). In other words, you should have no problem running faster memory modules on these motherboards than what they advertise as their max-supported speed.

The board also has an integrated Realtek Gigabit LAN controller along with Audio Boost technology for high-quality sound output and an isolated audio PCB design that eliminates interference from other components such as hard drives or optical drives which ensures clean audio signals at all times.

Product Overview

MSI is a well-known brand for gaming hardware and its Tomahawk series has received positive reviews from many people. I’m pleased to say that MSI’s latest offering, The MSI MAG B550 Tomahawk, is worthy of its predecessors. Everything from performance to design and sound quality is great; it does cost more than your average motherboard, but when you look at what it offers for that price, you’ll agree that it’s well worth it. Let me be clear: if you want to build an inexpensive PC but don’t mind not playing some modern games in 4Kor using tons of hardware-intensive applications, then you can use other options like ASUS or Gigabyte.

Specifications & Features

MSI introduced its all-new MAG series and it has been designed for those who are seeking simplicity. With the MSI MAG series, you can easily find a gaming motherboard that satisfies all your needs. You’ll be able to simply connect your CPU and GPU, install and use it with ease. Every new MSI motherboard from MSI GAMING motherboards to X-series motherboards supports multi-GPU setups on both AMD CrossFireXTM and NVIDIA SLITM technologies. The ultimate Personalize your PC with adjustable color LEDs which give a dazzling lighting effect with virtually unlimited choices of illumination modes! Depending on what types of components you plan to use, choose between six different LEDs hidden behind three areas on each side of your PC so you can create a truly unique look that matches your personal style!

Design and Layout

The layout of MSI’s motherboard is very simple and clean. The model we tested came in white and black, but MSI also makes a variation with blue accents for those who are willing to pay a bit more. One of our favorite features about MSI’s model is that it comes with RGB lighting. This isn’t just some gimmicky feature you’d only find on one or two of your components either – it can be applied to almost every part of your system. You could even create different zones to control each part individually if you wanted to get really creative with it! Not only does it come with RGB lighting features, but there are plenty of plug-and-play features for those looking for something a little more advanced as well. There are three 4-pin fan headers, which should be enough for most users. However, if you plan on running multiple fans from one header (or perhaps have an unusually large case), you might want to consider getting an adapter cable that allows you to connect additional fans into a single header. It also has plenty of SATA ports for hard drives and SSDs (8x SATA 6Gb/s) so you won’t have any trouble adding additional storage devices to your PC. It has an M2 slot for M2 SSDs up to 110mm in length, so adding a small amount of extra storage space shouldn’t be too difficult at all.

Test Setup & Benchmarks

In order to test, we will need to test with comparable systems and benchmarks. This motherboard was tested on our $700 gaming PC build which includes an AMD Ryzen 7 1700X processor (more on how I picked that CPU below). Other than that, it’s running a Gigabyte RX 480 8GB graphics card and 16GB of RAM. While those aren’t necessarily MSI brand parts, they’ll allow us to evaluate how well MSI’s motherboard performs without skewing results because of a hardware-dependent setup. We’ll be using 3DMark Fire Strike Ultra as our benchmarking suite for both stock performance testing and overclocking.


Overall, MSI has come up with a great product that’s going to satisfy most gamers. It performs well while also having very nice aesthetics. The motherboard is easy to use and it comes with a lot of great features as well. Some may find that it doesn’t have enough cooling when overclocking, though. I recommend getting an aftermarket cooler if you’re going to be overclocking often. Overall, however, MSI has done a great job creating a motherboard that’s worthy of being included in our Best of 2018 lists! For all these reasons and more, MSI deserves our highest honor and awards it a 10/10 score for design and overall quality!
