Not the most expensive board, works great though. Has good audio options, and good connectivity (with 6 sata ports and a nice amount of PCIe slots). Worked out of the box with my new 5700x

I've purchased 3 different MSi products (2 motherboards and 1 laptop). The first motherboard and laptop were great feature wise. They were reliable and I never had any issues. So far this well designed motherboard has been running solid for 24 hours and no crashes or anything of the sort.

The motherboard was very easy to install and clear about what goes where. All parts clicked into place nicely. Only issue I had was with the cooler brackets, my wraith prism cooler wouldn't lock into it properly so I had to use the brackets that came with the cpu. Other than that and the fact it doesn't have wifi, it's a great atx motherboard to get on a budget since it has pcie 4.0 for both the gpu and m.2.

En cuento a sus características es una Motherboard muy completa y de una muy buena calidad, único detalle que le encontraría es que la cubierta de los puertos es fea, pero ya es un gusto personal y no afecta en nada al rendimiento del equipo

My 4th build with a AM4 motherboard. This board does everything I need, seems sturdy. No issues with updating firmware (there's a button...this is essential because if it fails during a firmware update, your motherboard is a brick -- this happened to me once. This motherboard has a button and USB slot so you can reinstall the firmware and not lost a motherboard! That by itself is worth it.)Didn't run into any problems at all -- but noticed nice things I appreciated when building.

System Specs:This mobo with a brand new shipped to me last week Ryzen 7 5800x that was on supported list since Rev 1.System worked great for 2 days until Windows 11 update declared my CPU no longer supported!After months of denial this issue is known to MSI and rather than recall all boards to fix it - they still shipped these broken motherboards.Installed the latest 04/24 update allegedly correctly and still won't work. This is a brand new PC build - all parts compatible, it's bull that I get this error.Bought in October 2023, open installed on May 24, ran for 2 days then update, then BSOD so fast that I can't even bring up the error message it was sending. After BSOD forces reboot - at times it can stay in desktop. Fresh install Windows 11 and 10, both failed. Note all HDDs clean low level formatted, with no issues in any other device including an unopened NVMe 1TB drive used for initial Win 11 install. Gave more BSODs after the last install.No other software installed btw, no games, no apps no nothing, just base. No RAM issues either, though they did state an apparent IRQ conflict but board refuses to boot into safe mode, just BSODs.Stay away; it's as bad as ASUS tech now; their tech just isn't up to snuff. Worried my new Gigabyte board may be broken on arrival as well.

Warnings: RAM is close to CPU, we had to raise one of the cooling fans on the heat sink to clear the RAM. Only has 1 CPU fan port, and 1 pump port, but you can just connect the CPU fan to one of the 5 case fan ports. Was difficult to align mounting screws properly, but that could have been my fault.Overall pretty good, but im only 1 day in so....

I've had the motherboard for three years now. In that time, I've used three different GPUs (lower, mid, and high end) with the board with no issues. I've also overclocked a 5800x to 4.5 Ghz at 1.150V and it remains completely stable. There have been no problems with temps, and I haven't run into any issues with component compatibility as of now.The BIOS interface is simple and easy to use with a sleek design. You can toggle between basic and advanced views, and if you still can't find what you're looking for there is a handy search function in the BIOS. I've had no problems updating the BIOS through the UI and through the handy BIOS flash button on the back of the motherboard.Overall, the board has been great to me for the last three years.

I flashed the BIOS, did everything I can think of, and still I get random BSOD: memory corruption, bad drivers, many various errors from Windows 10. I searched online and found out that other people complain from the same Motherboard model for random erros. I didn't expect this from MSI and doubt they would replace my motherboard, but my next Motherboard won't be an MSI for sure. You lost me MSI.

It has 7 USBs with an USB C in the rear, plenty enough to add a lot of peripherals if nescessary. The board itself is pretty thick and solid, I had no issues afterwards when I was wrestling with my PC trying to install it inside (yeah, I should have known I should have put the bolts first). The heat is pretty good at stock speed as I'm not an overclocker anyway. It's quite handy to have 6 SATA ports at the sides so it's easier to plug them in my opinion. I love the fact it has 2 PCIE M.2 Slots so I might instal a NVME SSD in a near future. I didn't do any bios update and I had zero problem installing my Ryzen 7 3700X and my Crucial Balistic RAMs at all.

Great price for a more budget oriented AM4 motherboard. Preparing it is even easier since it's already ready for Ryzen 5000 CPUs. Only critique I have is the rear i/o shielding feels low quality but this isn't a serious problem since people shouldn't look at the back of the case.
