MSI MAG B550 Tomahawk

I had a great experience using this motherboard to upgrade an older system. Everything works out of the box using Windows 10. I didn't have to install any extra drivers or bloatware from the manufacturer. Setup and configuration was easy. All the connectors are accessible and nothing is placed in a weird spot, so cable routing was a snap. You should be aware that that there are a limited number of PCI lanes shared between the PCI-E connectors and the M.2 slots. It's not a big deal but read the motherboard manual for a complete description of all the PCI-E slot and M.2 slot configurations to understand how many lanes you can have accessible. For me, other than a video card I used one M.2 and a bunch of PCI-E x1 cards so the limited lanes wasn't an issue for me. The M.2 slot connected directly to the CPU is also right next to the CPU socket so be aware that there will be limited space around it for a large M.2 drive cooler with the CPU cooler next to it. I'd plan for that accordingly. You'll want to use that for your boot drive because it's the fastest M.2 slot on the board and doesn't waste any PCI-E lanes like the others do. I had to do a BIOS update and it was a little tricky; the MSI BIOS has no problem detecting USB thumb drives but the BIOS updater mode only supports specific USB thumb drives. So you will be able to see your USB drive easily in the MSI "Board Explorer" display, but still have the BIOS update tool be unable to detect it. I happened to have a bunch of old random USB thumb drives from 512MB to 8GB and just tried different ones until it worked. So if you have issues updating the BIOS it isn't you: it's the thumb drive and you'll just want to try a few. Not a big deal but this isn't clearly explained in the motherboard manual. The motherboard has HDMI and DisplayPort outputs but there is no onboard video; this only works if you have a CPU with integrated graphics. I didn't, I used a Ryzen 5900X so you'll need a PCI-E video card for most kinds of CPUs. The built-in WiFi works great. I didn't like the included antennas but it uses a standard WiFi antenna connector so you can put on other ones. So overall this is a great motherboard. Everything works, there's no hidden gotchas, and it is quite stable. Performance is exceptional. Since I had a lot of DDR4 RAM this was the newest motherboard I could get without having to dump the old RAM and buy a lot of DDR5 so I'm quite happy with it.

I did need an ethernet connection or a thumb drive with the downloaded Wi-Fi drivers to get the Wi-Fi started but it's a great motherboard. Very durable and works as intended. There are plenty of USB, video and audio ports. The price was right too.

Had a gigabyte 450 go bad after 4 years of use, a computer tech guy mentioned he only uses MSI boards as the quality seems above average compared to other brands. I had never used a MSI board, but this board is really great out of the box. Updating bios was a snap, the system went together very easy. Was able to keep my win 11 in place and change drivers without much trouble. In other words no fresh install of windows. The wifi runs really good. In the future if I upgrade I will only be looking at MSI. l was looking at upgrading and spending 1500 after my old board died. For the 170 bucks on this MSI board; my computer with AMD Ryzen 7 5800X3D 64 megs of ram,,, running pretty strong. I could not be any happier!!!!!!!!!!!!

This was my first PC build in more than 20 years. This motherboard is great. Its one downfall in my eyes, it could use a couple more USB ports in the back (competitor ASUS does better here.) But I have no complaints. I don't use any LED stuff, so you're on your own there, can't tell ya.
