Easy to install motherboard
Best mobo for the AM4 generation. Easy to install and worked right out of box. I did not need to update the bios. It also is visually striking without all the anoying led. Although you can hook up ungodly amounts of led if you choose. I highly recommend this board

Best AM4 board for the money
Best motherboard I've ever had. Works very well, no issues and booted first try. At a time when PC hardware is expensive and hard to find, the AM4 set up is the best option for gaming and this motherboard will definitely buy some time until the next upgrade. Its VRMs will handle the best of the AM4 CPUs and have more than enough cooling to handle overclocking due to having over kill heatsinks. Great optical audio out for it being built in. Decent USB ports though it could use a couple more. Operating with a liquid cooled Ryzen 7 5800x, MSI RTX 3070, 32GB DDR4 3200 RAM, Samsung NVMe 980 M.2 SSD. CPU overclocked hitting 4.82Ghz, GPU overclocked, RAM overclocked to 3600. In a case with proper fan placement it never runs hot and runs most everything at high to ultra settings at 120+ FPS. I intentionally have my FPS capped at 120 (118) for cooling purposes and to not stress my gpu so that it lives longer but it hit 244 FPS when uncapped (on a 244Hz monitor).

Works for Ryzen 5000 after relatively painless bios update
I bought a Ryzen 5600x and you need a bios update to run these chips for any mobo currently available as far as I'm aware, none will run these new generation Ryzen chips out of the box. This mobo does have the feature where you can flash a bios update without a CPU installed. This is VERY key, if like me, you do not already have a compatible AMD chip. 1st Mobo I bought did not have the BIOS flash ability. And would not post. Nada. I found out the hard way that the only way to update the bios, unless the mobo has the CPU-less bios flash ability, is to A) already have a compatible Ryzen chip on hand or B), I guess AMD will send you a chip on loan to perform the bios install. Those are the only solutions, seriously?? Would have taken weeks seemingly to get the loaner chip in the mail and what a colossal PITA. Nowhere in that mobo's description was any of this mentioned. It just said the BIOS could be updated without elaborating on how painful it was going to be and how many prerequisites and hoops to jump through. Great. False advertising, I call that. So I sent back the mobo and got this one. Got the proper bios install file onto a thumb drive, put it into the proper USB slot on the mobo, pressed the button, waited with baited breath....and it actually worked. You can google the instructions. It's not too hard. So now I'm rocking the new Ryzen 5000 chip, this mobo was pretty easy to work with, seems well built, good connectivity, no Wifi but I didn't need it. You don't need to futz around with a back plate, which is a long overdue improvement in mobos as far as I'm concerned. I did have to go into the Bios and change a setting, UEFI to CSM I believe, to get it to boot out of bios and into the windows boot drive. I do kinda wish there were a few more USB ports. But the fact that it was relatively painless to update this mobo's bios, and the fact that the process for doing so *actually worked*, is invaluable. I also got significantly faster transfer speeds via PCI between hard drives than I was used to with the old setup. I'm up and running and happy with this mobo.

Wonderful replacement for my quirky previous board.
I bought this as a replacement for an ASRock X570 Steel Legend that I've had since they first launched back in the summer of 2019. As, it was gradually showing more signs of failure over the time that I had it in my system. First, the onboard audio stopped working. Which, I just switched over to using the audio interface that I had for recording. So, that didn't bother me TOO much. I also was noticing that games were starting to have more and more issues with micro-stutter. I did some tinkering and got it behaving a little better. But, that never fully went away. The final thing that prompted me to look for a replacement was I started having really bad lag issues while playing online games. Yes, legitimate lag. Not the "I missed my shot, the stupid server must be lagging!" type of lag. As, I'm very well aware of and openly recognize how bad I am at competitive games. This is "friend and I are in a car together, friend awkwardly crashes car into a building, I wonder why they did that, then the game suddenly snaps to us being on a completely different street and still moving" level of lag. Quite a frequent occurrence, at that. I tried a list troubleshooting steps. Driver updates for everything, lowering the games' settings, reinstalling the games, cleaning the operating system, reinstalling the operating system, adjusting settings and also resetting the router back to factory defaults, port forwarding, pestering the cable company about connection issues, different ethernet cables, etc. I figured seeing as the motherboard was already having other issues, perhaps it was drying out even further. So, I decided to start looking for replacement options. Which, being that the 7000 series processors had been out for a while, I knew that my options would be slimmer than before. At least for a NEW board. Also, pricing may not be ideal. But, reading a bunch of reviews and doing comparisons, this particular board sounded like it would be a solid choice without having to spend a lot more for the available higher end boards. I had mixed feelings about "stepping down" a notch to the B550 chipset. But, upon further consideration and reading, the performance difference was minimal. Plus, I didn't use enough of the extra features that X570 had over B550 to really be concerned about that. So, I went ahead and grabbed it. Yeah, it was a great decision to grab this board! Though there are still occasional lag quirks (which, is to be expected, honestly), there was a HUGE improvement in connection stability with games. Plus, games and the system overall feel notably smoother than before. Far less micro-stutter and things just feel more responsive, as a whole. Oh, and I have onboard sound back. Which, is cool too! But, yeah, I am VERY happy with this board! Everything about it seems to work great! And, I can't think of any major complaints. Maybe that the UEFI menu feels a little messy to navigate. But, that could just be a familiarity thing. Also, I don't use any of the "software suite" stuff that often comes with motherboards. That's just unnecessary bloat, to me. So, I can't comment on any of that stuff. I was worried that I was getting a step down from my previous board. But, that was not at all the case. A very solid choice for anyone that plays demanding games, does content creation, and/or software/game development.

Great motherboard, solid build
This review is for the MSI MAG B550 Tomahawk motherboard. I purchased one for $179 in January 2022, and it has been a solid performer. I paired it with an AMD Ryzen 5 5600G processor, 32 GB of G.Skill 3200 RAM, and an EVGA 750 watt power supply. The board is well-built and has a solid, hefty feel to it. Installation was a snap, and the user guide includes ample diagrams for component locations, pin-outs, and connectors. I flashed the BIOS before install for the new 5000 series Ryzen processors (a simple process, well-documented on the MSI website), and I didn't have any issues at start up. The Ryzen 5 5600G processor comes with a Wraith Stealth cooler, and removing the stock cooler bracket (4 screws) was a cinch, then just mount the Wraith cooler with 4 screws and done. After a 48 hour burn-in session I've been running the machine from 8 to 12 hours a day for over a month and I haven't had a single issue. I do mainly gaming, music and video streaming, word processing, and web browsing. CPU and board temps have not gone above 85 centigrade even when gaming. There are 6 SATA ports, which is plenty for most mainstream rigs, and plenty of USB connectivity counting the motherboard ports and front panel ports on my case. If you're planning on hanging a ton of USB devices off your board you might want to look for one with more connectivity, but for most this board will be plenty. I'm no audiophile, but I know what sounds good, and the audio from this board is great for music, movies, and gaming. The PCH and M.2 heatsinks are a nice touch, and the minimal amount of LED lighting on the board is pleasant and low-key. I haven't yet used a dedicated graphics card (waiting for prices and supply to ease), nor am I using the M.2 slot (I have 2 SATA drives installed). The UEFI Bios interface is presented well and provides mutiple memory profiles and overclocking options for those who are so inclined.. I haven't overclocked the board, but I did bump the RAM speed from the stock 2166 up to 3200, which improved my gaming frame rates. I'm happy with the price, features, and performance of this motherboard. I deducted one star from my rating because I'm not happy with MSI's policies. In order to register the warranty they demand that I install the Chrome web browser on my computer and create a user account, and I won't do that. They don't offer any other options for registering the warranty. If they want to form an unholy alliance with Google that is their business, but they won't dictate what programs I install or what web browser I use. I may or may not ever buy another MSI product, but I am pleased with this purchase.

Rock-solid motherboard for Ryzen. Fast, stable, and easy to work with
Iโm using MSI MAG B550 TOMAHAWK with my Ryzen 7 5800XT, and itโs been absolutely flawless. It booted up right away with no issues, the BIOS is clean and easy to navigate, and all components like RAM, SSDs, GPU, and AIO cooler worked perfectly from day one. The VRM temperatures stay cool even under load, and the board handles overclocking without any instability. Iโm running 32GB DDR4 3200 MHz memory, dual NVMe drives, and a Radeon RX 5700 XT. Everything runs smooth and stable. It has plenty of USB ports, strong build quality, and a great layout for cable management. The RGB lighting is subtle but adds a nice touch to the setup. Overall, one of the best-value B550 motherboards you can buy. It performs like a high-end X570 while staying affordable and reliable.

Great B550 Board
If you want a solid board for a Ryzen 3xxx or 5xxx, the B550 MAG Tomahawk is a great choice. 1) For under $200, the motherboard has quality vrms that can handle those monster 12 and 16 core processors (Hardware Unboxed has videos that verify this). I have the board paired with a Ryzen 3800XT for a work and play build and I don't worry about overheating my vrms. 2) If you are into overclocking or just tweaking your processor and ram, all the parameters are easy to find in the bios. I don't overclock my processor but I see the many parameters while manually tuning RAM. 3) The RAM QVL list is extensive, which is a major positive when dealing with Ryzen builds. Find QVL listed RAM and you can turn on A-XMP to easily run your ram at the rated speed. I had no trouble with running Hyper X Predator 3200 CL 16 DDR4 RAM with A-XMP and was able to get better tuning with help of the Ryzen Memory Calculator 4) Two M.2 NVME SSD slots (Gen 4 and Gen 3) and 6 sata ports (none disabled when using M.2). This is a major plus if you run SATA SSDs and HDDs for gaming and mass storage needs while still getting the benefits of NVME speeds for booting and apps. The NVME slots come with removable heatshields, which is a nice bonus if you have an NVME that supplies its own heatsink 5) There's a switch for turning the color lights off on the board. Great for those of us who are more about function and without see through cases. 6) The IO Shield is integrated with the board. This is great for not having to fight with the shield when lining up your motherboard mounting. 7) Reinforced video card PCIE slot. Those gaming GPUS aren't light! 8) Onboard sound is solid quality and includes SPDIF output 9) The motherboard layout is great for accessing the various ports and installation hookups during a build I can't think of much else to say. I've had this motherboard for a build since October and its having no problems being the heart of my personal use system where I practice programming, make audio for language learning, play some triple A games on Steam, and do other trivial things (web browsing, Office, etc)

Durable motherboard Quality, Excellent Performance, and Great Features!
Paired with the Ryzen 7 3700X, RX 6650 XT, 700W power supply, and 32GB of RAM, it's been a very good combination. One of the standout features of this motherboard is the 2.5G LAN support, which provides blazing-fast internet speeds. This is a game-changer for online gaming and streaming, as it reduces latency and allows for smoother performance. Iโve noticed a significant improvement in network stability and speed, especially when multiple devices are connected. Another aspect that caught my attention is the six-layer thick PCB design. This not only enhances durability but also improves signal integrity, which is crucial for maintaining performance and stability. The build quality feels solid, giving me confidence that it will last through many upgrades and years of use. Pairing it with the Ryzen 7 5800X3D would likely be an excellent choice for even more powerful gaming performance. Overall, the MSI Tomahawk delivers exceptional performance with its advanced networking capabilities and robust construction. I highly recommend it for anyone looking to build a high-performance system at this price range!
