## Description

Buy

Review: If you want a solid AM4 board for a Ryzen build, this is a great foundation - If you are looking at the MSI B550 Tomahawk and wondering whether it is a dependable base for a Ryzen PC build, yes. A motherboard is not the flashiest part of a build, but it is the part you really want to feel solid and well laid out. This board feels sturdy, the layout makes sense, and the connections are where you expect them to be. The M.2 support, PCIe options and 2.5G LAN make it feel like a board with room to grow rather than something bare minimum. My tip would be to update the BIOS if needed, plan your front-panel and fan headers before fitting everything, and enable the right memory profile once built. Strong board and five stars.
Review: A great choice at the right price - I just upgraded to this board coming from an aging Gigabyte board with a Ryzen 7 1700. Thankfully this board was at a good price and lets you flash the bios to allow it to take the latest 5000 Ryzen CPUs. You can do this with no other hardware attached to the board apart from the power supply in the 24 pin and 8 pin connectors. Nice and east too. Just grab the latest NON-BETA release, pop it on a formatted (Fat32) flash drive and make sure you set the extension to .ROM on the downloaded bios file (See YouTube for a guide) Then plug the stick in the highlighted USB port on the rear IO and press the button above it (It's recessed, so us a pencil or something) It took about 5 mins, but you might want to wait another 5 mins after it stops flashing, just to be sure it's complete. I then powered down, added my hardware and that was that. It took about 15 mins from getting the file to being ready, and that's factoring in extra waiting times to be sure. The board is built well and weighs a fair bit, thanks to it's chunky heatsinks. I've overclocked a 5800 to 5Ghz with no issues apart from temps, which are a little higher on the 5800X anyway, due to how they are made. I'm not running it at that though, I've decided to keep it at 4.8 and get the voltages down as much as possible. I'm really pleased with everything! Motherboards have come a long way over the years and this one is very capable. If you get it on offer then go for it. You're likely looking at x570s too, so keep those in mind when comparing prices. The MSI x570 is another good choice if it fits your budget too and you want the extra bells and whistles. This board has 1x Gen 4 NMVe slot and a single PCI-E 4.0 slot for the GPU. So you're still getting good specs. Check out the specs in full vs some of the others out there as they do differ... some by a fair way too. I'd buy MSI again for sure (Coming from a long time Gigabyte customer) It just fits perfect and has been trouble free. The bios is awesome to work with too.

## Questions & Answers

**Q: How do you get WiFi to this motherboard**
A: Buy a WiFi PCIe Card! You can buy a wifi 6 card for between twenty and forty bucks and they take minutes to fit. If you don't need an ultra-fast and capable wifi connection you can also buy a wifi dongle that plugs into a spare USB port (preferably a USB 3.0 port) however I'd strongly recommend a PCIe plug-in card.

**Q: Will this support Ryzen 7 3700x out of the box?**
A: Yes it does finished my build with it yesterday

**Q: Can it support mvme ssd?**
A: It has support for two NVMe devices although only the first supports PCIe 4. The second supports PCIe 3. I use both slots with each having a capacity of 1tb. Either slot can support both PCIe 3 and 4 devices but you only get the fastest performance matching a PCIe 4 drive to the first slot. The X570 motherboard offers 2 slots and both are PCIe 4 capable.

**Q: Does this mobo fit a musetex phantom atx mid tower case?**
A: That depends on whether the Phantom ATX mid tower case can
accommodate a motherboard with the dimensions 12 in. x 9.6 in.
(30.5 cm x 24.4 cm).

### ⭐⭐⭐⭐⭐ Great board for the price - has almost everything you'll need.
*by A***R on 23 July 2021*

First of all before going into anything further, I'd like to point out the review below me is incorrect and your older GPU's will be fine. It is likely that the user beneath me reporting his GTX 980 didn't work, did not have an up to date BIOS on his board (mine had a BIOS revision compatible with the Ryzen 9 5900x CPU, if he had a Ryzen 5000 series CPU, it's likely he had to flash it if he was recieving no video) and didn't do enough research. Your older graphics cards will work with this board, I originally had a GTX 960 in here and it worked right away. I also didn't have to flash my BIOS... some boards made prior to 2021 of this variant might need a flash - in which case, look up a YouTube video for it - it's a pretty simple process and doesn't require a compatible CPU to do it... just a USB pen! Easy installation into most modern ATX cases as no having to mess around the I/O shield as it's pre-applied to the board as part of the heat sink... long gone are the days of messing around with those unless you go for a cheaper board. There's enough space between the PCIE x16 4.0 slot for your GPU to the lower down PCIE x16 3.0 slot for another peripheral with a modern graphics card installed... although I'm not sure about the width/bulk of RTX 3090, a RTX 3070 fits here fine with enough space inside a Corsair 4000d Airflow. Lots of system fan headers for a good case to have everything connected individually for monitored RPM usage on most, if not all your fans (depending on how many you have!) without having to connect multiple fans to the same header. The CPU PUMP header can be used as a CPU OPT header also (optional CPU fan) if you say, want to monitor both fans of a cooler like the very popular Noctua NH-D15. The only cons here I'd say are as follows: Two PCIE x1 ports... really? Just make them X4's or X16's are PCIE 3.0 - so many modern peripherals don't fit an X1 slot and need the wider variant. if the PCIE x16 3.0 slot is in use, I believe the lower M.2 slot also become nulled... I've not treid this myself, but the manual mentions it. Please look up the manual and read about this yourself for more information if having two NVME M.2 drives is a necesscity for you... (the lower M.2. slot is also 3.0, not 4.0) for me, it isn't, and the one NVME 4.0 slot is enough.
