  • great price, and great product MSI MPG B850 EDGE TI WIFI Motherboard, ATX
Model: MPG B850 Edge TI WiFi
Used this CPU, on my first PC build. I've been using it for about 2 months now, it works great. The entire experience from installation to booting up for the first time was totally painless. I never had to get additional info, from what I already known from basic building computer knowledge. First time build with all new components, I have build pc with used parts. I totally recommend this Mother Board, it looks great, and the quality of the parts are great. Wifi, connectivity is faster as it uses one of the latest standards. Bios update happened as soon as I booted the MB for the first time, and it keeps updating itself. This motherboard, has limitless possibilities on how it can be use, either for basic game users or advanced. ... show more

  • Best B850M You Can Get
Model: MAGB850MMORTARWIFI
Very stylish motherboard. Easy to build in with easy installs for the wifi and bluetooth antenna, including an very easy way of installing the uninstalling the GPU to the PCIe lane with the use of a button instead of a clip. Motherboard has no issues and has been working perfectly without any problems. Undoubtedly the best mATX motherboard currently in the market. ... show more

  • Very solid MATX mobo
Model: PROB850MAWIFI
Had it for around a month now, no problems so far. I like the abundance of usb 3 on the io, and it looks great in a white pc. The toolless m.2 installation was kind of strange as I've never encountered it before, but I figured it out. Overall, great motherboard, good stability, great features, looks clean. ... show more

  • The mATX board to get!
Model: MAGB850MMORTARWIFI
This is such a great matx board. As of right now, I think it is the best value and up to date mb out ther for matx. The board is very stable, I paired it with a processor aimed at productivity with 64 gb ddr5 6000 and a nvdia gpu. I was able to push all cores to just below 5.8 ghz with only a 240 aio, average temps at that point were at at 94c. I just wanted to check how far I can push the processor while keeping it stable, ram was oc'd to 6400, running very stable as well. I run the whole system with a corsair rm850x, the psu didnt really break a sweat. The board supports pcie gen 5 for the two front facing m.2 slots and the bonus slot on the rear ofr the board runs @ pcie gen 4. The graphics card slot is higher up on the board, closer to the cpu compared to most asus boards. That might be important if you are building in a tight matx case as I did. The board is also equipped with wifi 7 and here's something you wont find on other matx boards, a 5gb ethernet port. 10gb would have been a dream but 5gb is plenty enough for my use. The bios for the board can be really simple but if you dig in, you will find all the settings you can expect to find to overclock your cpu and ram. If you are into rgb lighting, there are enough argb connectors for that. Mystic Light is more stable than ever, just make sure to get rgb devices that are compatible with msi mystic light. So, for what it's worth, I am highly confident that the MSI Mortar is the mATX motherboard that will be more than good enough for most diy builders out there looling for a high quality motherboard. Also important to note, this board has no known backdoor at this time and nor does the MSI software give any access to remotely run malicious code on your pc. I habe not tested this board on linux but, I assume it will work just as flawlessly. ... show more

  • Everything worked right away, love that!
Model: MAGB850MMORTARWIFI
Not an expert or anything, but I really liked this board, super easy to install, the BIOS didn’t give me any problems and everything booted up first try. The Wi-Fi is crazy fast and the board looks super clean in my case. No flashy RGB or crazy stuff, just solid performance. If you’re building something compact, this one’s a win. ... show more

  • Mediocre at best.
Model: MPG B850 Edge TI WiFi
Board is not similar to the intel version at all so if you come from intel to AMD on what appeared to be the same white out board, you will be losing a few headers and the usb c for the front to its connection is not possible due to the location on the board. My GPU literally prevents its connection and so im out of a USB C port for the front of my case which is dumb. ... show more

  • Beast of a motherboard, well worth the price.
Model: MAGB850MMORTARWIFI
Coming from an ASUS TUF B650M, this motherboard has been nothing short of great to work with. The bios settings for voltages, specifically VSOC and the DDR5 DIMM, actually change when you set them to different values. The bios is super easy to navigate and it is not confusing as there is not multiple settings of the same kind to change. My system started right up after an M-FLASH to the latest bios version, and I am currently running a 9800x3d and 6400mhz cl32 DDR5 at EXPO with altered values, and it runs flawlessly with the tweaks I've made to lower voltages down without instability. Please take a look at this for your next MFF/SFF build, you won't regret it. Would like to point out that the PCIE slot would align with the top most slot on the motherboard, allowing for better GPU width clearance at the cost of possible cooler position conflicts. Looks great while in the case as well, much cleaner look without the MSI DRAGON LOGO ... show more

  • Excellent Value with all the important features for now and the next 3-5yrs.
Model: MAGB850MMORTARWIFI
Excellent value. Paired with Ryzen 9950x and 5090 in a Jonsbo D32 Pro. This had100% of the X870 capabilities that I needed for hundreds less. WiFi 7, Gen5 PCIe for GPU, dual Gen5 M.2 support when paired with Ryzen 9xxx CPU, tool-less M2 installation, easy and innovative unlock/lock GPU system. Just enough fan headers to manage the six fans in my build. The mATX form factor is the sweet spot for small form factor builds without much compromise. ... show more
