Great motherboard for the price, has everything I wanted for my build. Built in I/O shield makes installing even easier.
MrBenSpeck –
Price beat any other website. Been looking for one for a while and Best Buy had the best selection.

My Setup:
-MSI B550 Tomahawk (this board)
-Ryzen 7 3700x
-Mushkin 2x32gb ddr4 3600 ram
Thoughts:
This board just works. I haven’t had any issues with compatibility and it fires up every time. The VRM is great and I have no complaints. If you are looking for a solid board with good components, go with this.

I purchased this motherboard to go along with my 5800x because it seemed to get pretty good reviews. Installation was pretty smooth and everything seemed to be working OK, but I noticed that my computer would randomly get super slow after being on for an hour or two, and the only solution was to reboot. It would then be fine again for an hour or two, slow down, reboot, etc. I tried everything, updating drivers, switching ram, switching hard drives, and the problem persisted. I got tired of troubleshooting and returned it for an Asus board, and havent had any problems since.
Laxbro9090 –
This is a beautiful motherboard, and it works really well for me so far
pbrexn –
Tomahawk board looks amazing,worked perfect out of the box..Super sturdy Board.i absolutely loved building on this board
Raymon –
Great motherboard. It’s keeping up with my build. It’s great for the price.
Ryan –
Great motherboard for the price you cannot go wrong with any Tomahawks.
HomelessTadpole –
I needed an AMD mobo to start my PC build and this covered everything I was looking to get on a motherboard at a great price point. I didn’t need to break the bank on a “premium” tier board and this board sure seems premium to me for the features it has compared to my previous board. A solid product and one that flashing the BIOS for a Ryzen 5 5600X was super easy to do with the BIOS flashback button on this mobo. Would buy this same product over again without a thought.
Yeetuee –
Really good motherboard easy for oc. The board also really design.
rlamp2 –
Unfortunately the optimized memory slots were faulty right out of the box and couldn’t load out of BIOS.
yeayeahpoop –
MSI boards are always great and reliable, however i would have liked more usb ports and more rgb fan headers. If anyone is looking for an alternative I recommend the aorus pro b550 board from gigabyte. Got mine for even cheaper than this board and it has better features and value. If ports are not a problem for you, I absolutely recommend you keep this board, I had to return mine because of some compatibility issues on my end, otherwise i would still have this board today.

This motherboard is exactly what i needed, i upgraded from an a320 >< and also got a ryzen 5 5600x. best part about this besides having everything the average person would need, is flashing the bios with out a processor is super simple.
Best –
Overall a nice mother board, it fits very well into my Corsair case and handles all other hardware well and easy to install, would recommend!
CGerman –
Solid mid range motherboard with a solid feature set and plenty of usb connectivity. I have been using this board for 3 months now with no problems
Tfandango –
Full featured and good price. Very well made board.
mike –
Very good board until it asked for an update and died and no I didn’t do anything to it I know what I’m doing with computers
Matthew –
Great motherboard, easy to use BIOS, the BIOS flashback feature worked flawlessly for me to flash the mobo to support the 5000 series Ryzen cpus. Lots of fan headers and has a couple RGB and one ARGB header for all your lighting needs
Josh –
Could not get Ethernet jack to work on the board. Had to return the board. Had no issue getting the new Asus board to connect to internet.
Mikey –
Great quality motherboard, if your a gamer then this motherboard is worth it.
Teallaker –
This is a great motherboard! Super easy to organize and work with.
savannah –
works great! exactly what i needed for my first pc build
Rick –
Great motherboard, no complaints. has 2 m.2 slots which are great and just an overall good board
Will –
When I got the part it was broken and by the time I built my pc and found out they wouldn’t even let me return it so now I’m stuck with a broken board
Chris –
works great, i was finally able to use my ddr4 ram sticks
SteveGuy19 –
Great motherboard especially for the price. Does what a motherboard should.
Traumahawk17 –
This is a really great board. If I knew what I knew now, I would have went with x570 chipset. You cant go wrong with a tomahawk tho.
Brandon –
Good value board with headroom for overclocking though I’ve kept everything at stock (Ryzen 5600X). No issues and it was easy to build with. The RGB is pretty unremarkable and I leave it alone since I control everything else through iCUE. Only feature this is missing for me is Wi-Fi but I didn’t let that stop me from choosing it over other options.
grizzlybc –
Good MB so far. Good price, easy to install. Will update review if any issues occur
Entrey –
Exactly as described, easy to install, straight forward instructions and manual. Rgb is subtle but a nice addition.
Isaiah –
At this price theres no wifi or bluetooth but other than that pretty solid
User42 –
Very solid, looks great and works great too. Fast and reliable.
lady –
An amazing gaming board product by Msi every person to enjoy
Sonyshooter4 –
Solid motherboard that was used to built new gaming and editing computer
Kingjames2323 –
Computer running way faster with it price was right as well.
Septtiff15 –
Great producþ Everything it said it was going to be it was. Easy to install.
Kris –
Great motherboard, compatible with new Gen ryzens (if you update the bios) . The latest bios update fixed the USB flickering issue that plagued these boards as well, so just make sure you update to the current BIOS.
HoseA –
Good placement of all plugs.
Easy BIOS layout.
Didn’t come ready for my Ryzen 9 5900X, but it was easy to USB Flash update the BIOS.
Not a lot of RGB (which I like).
Love the dual LAN connections (great for work).
AverageshopperSoCal –
Great motherboard. Works extremely well with cases that have an external USB type C port on the interface. The motherboard also has a physical switch to turn the RGB lights on and off. Connectivity is great. Only thing is I wish it would have USB 2.0 ports.
Julez –
Works as intended.. Did not run into any issues…
Marioc899 –
It was very easy to install and looks great on my pc would definitely recommend
chaosjs01 –
The problem I had I recently fixed so No more problems and BTW Excellant Quality and fast as well…
Chris –
It’s works great but no built in Wi-Fi. Recommend buying a motherboard with it built in already
Widogast404 –
Simple to set up, makes sense visually. Decent board
DonnaL –
This motherboard was shipped to home after hours of installation displayed error in usb port which had none plugged it. Returned to local store , after diagnosing computer, it was a damaged motherboard. Thankful th tech manager took great care of us at Jensen beach store and had new one replaced in store as a purchase!
ChristopherB –
Very easy to install and setup. Have had no issues this far. Recommend any MSI products.
BriannaD –
Finally got all my parts together, built everything right and run it and…no display. Have narrowed it down to either the ram or the ports for the ram in the motherboard here 🙁 sadly now hunting for new ram to test whats causing the issue and hoping its not the board
MrMomo –
This is one of the best motherboard quality and price. The best choice if you are trying to start on build your own pc.
Dmoney –
It fixed all the boot issues that I was having. If you know what you doing when it comes to installation of motherboard
Jason –
Great motherboard still to this day. Been had this since 2020. Going strong for 3 years straight.
