Design and build

To begin with, I will tell you that the MSI MAG B660M Mortar WiFi is a motherboard Micro-ATX format (or mATX) which has a standard size of 24.4 x 24.4cm. It is built on a 6-layer black PCB with a few glossy black silkscreens that go quite unnoticed.

On the contrary, something that does not go unnoticed are the brushed aluminum heatsinks that it has has spread over its entire surface. These heatsinks have a generous size and attractive design with indentations and black lines that give the plate some charisma. Another thing that I was surprised to see is that both M.2 ports have their own heatsink, which MSI calls M.2 Shield Frozr.

Although as you can imagine the main innovation of this board does not reside in the heatsinks, but under one of them. Specifically, I am talking about that small heatsink that indicates the name of the model. And it is that under him is a brand new Intel B660 chipset compatible with 12th generation processors and most of their new features.

An example of these new features is in memory slots. At first glance they do not seem special but they can be installed up to up to 128GB of DDR5 memory in Dual-Channel configuration. Besides that and thanks to the Memory Boost technology of MSI, the speed that this memory can reach is of up to 6200MHz (OC).

Later, in the lower right corner is the area for the integrated audio. This is where the Realtek ALC1200 chip What is it 7.1 audio compatible and a pinch of japanese capacitors that give you the only note of color that this plate has.

Now, I have to say that the latter is not entirely true. And it is that the Mortar does not have any type of integrated lighting except for a few LEDs called EZ Debug LED. These LEDs light up and change color as the equipment starts up and indicates, in the event of an error, which part is causing problems.

However and although it does not have its own lights, the MAG B660M Mortar WiFi has some ARGB and RGB connectors in addition to being compatible with technology Mystic light by MSI.


In this regard, the Mortar is frankly well stocked as it has the latest technology. Specifically I am talking about a 2.5G LAN connection governed by a Realtek 8125BG controller and a 6E WiFi module with Bluetooth 5.2

PCIe ports

The MAG B660M Mortar WiFi due to its small format does not have many PCIe ports. The first one is reinforced with metal, comes from the CPU and supports the connection PCIe 4.0 x16. Then there would be the second port that is x1 and the third one of x16, both come from the chipset and because of this they are PCIe 3.0.

For traditional storage units, the Mortar has 6 SATA III ports managed by the chipset. These ports are located in the lower right part of the board and are arranged horizontally and vertically.
