This B550 board for me checked all the right boxes.

I paired this with an AMD 3600XT which allowed me to use PCIe 4.0 which I used for my storage solution. Blazing fast.

Other benefits that I was looking for in a board which other competitors didn't have:

-Rear I/O for 5.1+ surround speakers or optical input
-Mysticlight for RGB control
-PCI-E lanes not tied to SATA use.
-USB-C plug in for front case I/O
-Flash bios button
-Huge heatsinks for heat dissipation
-instant compatibility with the new 5000 series AMD processors for futureproofing

Some negatives that I can't really complain about since I was well aware prior to purchasing:

-I wish instead of the additional LAN port it had come with a WIFI/bluetooth option - remedied with PCI card
-NVME cards use PCI lanes so there is no way to fill up each PCI lanes and NVME at the same time. PCIe 4.0 is on separate lane.
-I wish there were one or two more rear USB options though this is nitpicking

All in all this is a great motherboard, performs great, and with great MSI options like the easy to navigate BIOS and utilities, backed with MSI reliability on boards this is a definite recommendation from me.

I have been using this motherboard for more than 2 months now and I could say a really sturdy motherboard. I'm using it for a ryzen 7 5700x and an RTX 3070Ti. With this configuration, the motherboard is performing very well. The only thing I wish this motherboard had was more USB 3.2 ports.

This is a top tier mother board, very good VRM and cooling, easy bios set up. I purchased a Amazon Warehouse item that said it was only consistent with being opened, but they obviously send one of the lesser value ones, as there was no operating manual, and could see that it had been installed.

Great quality motherboard. It was my first time building a PC and I was nervous, especially because I had to update the BIOS (my CPU is a 5000 series AMD) but thankfully this Mb has a bios flash button. I just used the USB method and it worked. Please make sure to plug in the connectors fully. I only half plugged in the motherboard connector during the bios update because Im a noob and was afraid it didn't update properly (but it did).
It made the building process smooth, the board is sturdy. Handle it gently regardless. The markings on the motherboard are clear but small. If you're building a PC for the first time please look up a tutorial that uses this motherboard for best results. Look up a bios flash update using this motherboard as well if you need it.

My PC turned on the first time with no issues! The mystic light is beautiful and I was able to sync my fans to the mystic light which looks awesome.
