    • Excellent features and best-in-class design
Size: mATX Style: MAG B660M MORTAR WIFI DDR4
Arguably the main feature on Z series boards is overclocking, and mostly gone are the days where overclocking provided substantial benefit. Looking to the B series, you can find most of the same features without paying the Z series premium, and all you're giving up is some extra power handling that does nothing for non-K CPUs, and a couple extra M.2 slots you weren't going to use. The B660M Mortar comes with two standard M.2 connectors, and that's plenty. Oh, and actually, while you can't overclock the CPU, you CAN overclock the RAM. Now in fairness, that can be a finicky process. But hey, welcome to overclocking, am I right? The point is, you can do it, and if your use case involves a lot of rapid data shuffling to and from RAM, the gains can be quite substantial. What else? The design is top-notch for a B series board. A beefy VRM ensures plenty of clean power available on demand for your CPU, and the substantial heat sinks all over the board help to move the heat away from your precious components and allow your case fans to do what they're meant to do. Lower temperatures, consistent performance, and less wear and tear. I appreciate that the board includes matching heat sinks for your M.2 drives as well, it's a nice touch. And seriously, I'm in awe at the sheer weight of this lad. For a small board, this has some heft to it. Absolute unit. This board is available in both DDR4 and DDR5 flavors, which I appreciate. As of June 2022, DDR5 still costs a lot more than I'd like to spend. And while my workloads do appreciate high bandwidth RAM, it's hard for me to justify paying twice as much for half the RAM when the performance gap isn't night and day. It will be eventually, but that's a few years off--by which time I'll probably have a new machine anyway. In the meantime, I can carry over the perfectly fine 16 gigs of DDR4 I had in my last machine and either save $50 now or double it to 32 gigs for only $50 extra. Incidentally, I'm loving the four RAM slots. Built-in WiFi? I almost never use WiFi on my PC. But the once or twice a year that I do... it's going to be great having it for the rare occasion I need it, instead of not having it, needing to spend $15-$20 on Amazon to order a WiFi USB adapter, wait a couple days, doesn't quite work, return it, order a PCIe card... just skip the hassle and pay an extra $10 up front for the feature, built-in, working perfectly. Boom. My only gripe is that at MSRP, you're paying twice the price of an entry-level board. Sure, that lesser board will run hot, your performance might suffer by 5, 6, 7 percent, and it will have one less USB connector than you wanted, or one less SATA channel, or one less PCIE slot, etc. But if all you wanted was a computer that just barely gets the job done, that would be a perfect fit. If you want a fine machine that does everything you need with effortless grace, the B660M Mortar is my top pick. And if you can find it on sale like I did, the price isn't even an issue--this was well worth every cent of the $145 I paid. ... show more

Review Image by Omar Delgado Omar Delgado
Motherboard is great. My last PC was huge so I decided to downsize. Has all the features i was looking for. Wifi might not work until you update drivers and windows. Biggest issue, not really an issue, inconvenience! i thought for sure on first start msi is supposed to start a program to update drivers. That wasn't the case. Just be prepared to be hardwired on to your internet searching for the drivers online. But well worth it! ... show more

researched mobos and this one always came on top. Using a 14th gen intel CPU and no issues, did not have to update the bios.

    • Looks solid
Size: mATX Style: MAG B760M MORTAR WIFI
So I made a rookie mistake. In my hurry to buy this motherboard which looks great, I didn’t realize Amazon had defaulted this to ship in MSI’s packaging. Which is just the box the motherboard comes in. I’m glad these boxes have thick walls, otherwise I’d have received a broken motherboard. As it is, the board looks a little bent but I’m not sure if that’s just natural or from the shipping itself. I see no cracks or breaks so I’ll test it when the rest of my stuff gets here. Board itself looks fantastic, has quite a bit of weight to it. I’ve owned MSI GPUs before so I’m expecting great things from this board. EDIT: Everything is set up. I have had no problems with this board. I've decided to go an unusual route in regard to audio. I bought a Sonos Ray soundbar on sale, I will use the optical connector on the motherboard to connect. I'll update later if it works. ... show more

    • Great So Far but Beware Buying Used
Size: mATX Style: MAG B760M MORTAR WIFI
Went together easily and nicely laid out with plenty of attention to detail. The complete instructions available online were very helpful. So far no issues. The BIOS was easy to flash. BEWARE if buying a used model . Mine shipped only in the original box with *one piece of bubble wrap* around the board. Very sketchy. I crossed my fingers and went for it though. ... show more

    • Best of the bunch.
Size: mATX Style: MAG B660M MORTAR WIFI DDR4
The MSI B660m Mortar Wi-fi DDR4 motherboard is a solid choice and a very well made product. It has won several B660 motherboard shootouts on various youtube channels, and for good reason. The VRM's and Power delivery system are the best available in the B660 motherboard space, with only the Asus Rog Strix series being comparable. But they cost nearly $60. more. The MSI Mortar has a 6 layer PCB, and it makes for a very solid, flex free feel to the board. The audio chip is a newer Realtek ALC1200, which is a step above other motherboards at this price point. It can easily handle an Intel 12700k CPU with an appropriate CPU cooler. I found the bios to be very user friendly, and the board has been fully stable running a four stick memory kit. The VRM's run cool and last but not least, the board looks great. I would highly recommend it. ... show more

I purchased this product for my gaming PC build. This motherboard works terrifically no issues, no overheating. It's a very fast reliable motherboard comes with the disc to install the lace updates and futures. Or you can download the online software as well. Had it for about 2 months now had no issues. I totally recommend this product. I also bought it when it was on sale also great for gaming. No lagging. No issues with the CPU as well ... show more
