Introduction, Specifications, and Pricing

MEG denotes MSI's top-end motherboard portfolio; MSI Enthusiast Gaming. For B550, this encompasses two boards, both from the Unify branch; B550 Unify and B550 Unify X. The latter sharing almost identical specs but appearing to be focused more on the enthusiast overclocking market rather than enthusiast gaming. As the title of this article has noted, we are looking at the non-X or standard MEG B550 Unify platform today, which priced very similar to the latest NZXT B550, and ASRocks own Taichi platform alongside the B550 AORUS Master and ProArt B550 from ASUS; certainly no lack of competition in the market for the Unify.

For specifications, the Unify is set up quite well with a 14+2 power design, MSI using Infineon stages this time around each able to handle 90A output current, plenty for the latest Zen 3 series. Of course, AM4 is the socket, and B550 is our chipset, so we have support for DDR4; 2133MHz JEDEC through 5100MHz via DOCP. Max memory is rated at 128GB across four slots.

Connectivity on this platform starts with six SATA 6Gb/s ports alongside four NVMe slots, one being Hyper M.2 and the other three Ultra M.2. USB connectivity includes four USB 2.0 ports with an added PS/2 port for legacy keyboard and mouse and four USB 3.2 Gen 2; one being Type-C and the other three Type-A.

Networking gives us the Realtek RTL8125BG 2.5Gbe chipset alongside Intel AX200 Wi-Fi 6. Additionally, the rear I/O houses HDMI and DP outputs alongside 3.5mm output for audio.

Pricing

The MEG B550 Unify carries an MSRP of $289.99 with a three-year warranty.

Unify uses Click BIOS 5 from MSI. This is one of the better BIOSes for those wanting to use mouse control. From the main menu, you have access to Game Boost CPU, XMP profiles, and boot priority. At the top, you can check both CPU and DRAM speed with hardware specifications to the right.

Around the center logo of the BIOS, there are six options for further control; these include board settings, overclocking, and M-Flash for BIOS updates. You can also dive into a hardware monitor to set up your chassis fans.

Motherboard Software

Audio - Dynamic Range

MSI MEG B550 Unify Motherboard Review 60 | TweakTown.com

Testing audio, we set up RMAA with a 3.5mm cable from the line-in to speaker out (green to blue) and set both to 24Bit 192KHz. Unify picked up 90.1 dBA in this scenario.

Networking

MSI MEG B550 Unify Motherboard Review 61 | TweakTown.com

With networking, we have 2.5GBE and Wi-Fi 6. Wired LAN picked up 2351 Mbps while the AX200 managed 1314 Mbps in testing.

Power, Thermals and Final Thoughts

Power Consumption

MSI MEG B550 Unify Motherboard Review 62 | TweakTown.com

Wrapping up testing, power consumption saw a low of 140w at idle and a peak of 367 watts under CPU load. These numbers may coincide with the lower performance we did see in specific benchmarks.

Thermals

MSI MEG B550 Unify Motherboard Review 63 | TweakTown.com

Thermals were on par at 28c idle and peak of 76c during testing.

Final Thoughts

I was able to keep the Unify on my test bench for several weeks and came away quite happy with the board's performance; through several AGESA updates, this has become quite an excellent overclocking platform and even runs PBO quite well on our 5800X. The design gives this board exceptional power capabilities well over 1000A from the Infineon stages, plenty for the 5900 or 5950X.

The colorway is a mix of PCB black and matte black on the heat sinks, fantastic in my opinion, as it allows for flexibility for consumers going with a themed build. Additionally, for those hating on RGB, you will be happy to know this board has Zero RGB integrated but can be added via headers.

BIOS and software are both easy to navigate; as I said earlier in the article MSI Click BIOs is one of the more mouse-friendly applications we have seen. Dragon Center, on the other hand, is a complete suite that allows you to manage your games and gaming profiles along with monitoring hardware and setting up any RGB lighting you have.

What We Like

Zero RGB: A complete blacked out motherboard!

M.2 Slots: Four M.2 for those wanting massive NVMe support!

Compatibility: AM4 offers massive socket compatibility.

What Could Be Better

Thunderbolt: No integrated Thunderbolt

Price:Pricing could be better considering the competition.
