MSI MAG B660M Mortar WiFi Motherboard - Close-Up
The MSI MAG B660M Mortar WiFi is themed in black and silver colors. This is a $250 US+ board and is on the expensive side within the B660 category. The motherboard comes in the Micro-ATX form factor and is jam-packed with features.
The board uses the LGA 1700 socket to support Intel Core processors. The socket is compatible only with Intel's 12th Generation core family. The socket has a protective cover on top of it that points out the exclusivity with Alder Lake 12th Gen CPUs & refrains users from running an older 11th and 10th generation CPUs as they won't fit in the socket at all and forcing them in the socket is only going to cause permanent damage to your motherboard.
Next to the socket are four DDR5 DIMM slots that can support up to 128 GB dual-channel memory. These slots are rated to support XMP profiles up to 6200 MHz (OC Plus). The DIMM slots feature metallic shielding around them for extra durability. Each slot is labeled, making it easier to install DIMMs in the proper orientation. DDR5 memory comes with a different latch position so forcing a DDR4 module into a DDR5 slot will cause permanent damage.
The MSI MAG B660M Mortar WIFI packs a 12 phase power delivery configuration that makes use of the Renesas RAA229131 (75A) MOSFET. The motherboard also makes use of a 6 layer PCB with a 2oz copper design.
As you can see, the VRMs are getting ample cooling from two massive aluminum-based heatsinks.
The CPU is supplied power through an 8+8 pin power connector configuration. This will feed the CPU with up to 300 Watts of power. The Intel 12th Gen Unlocked CPUs are very power-hungry with the maximum turbo power rated at 241W for the Core i9-12900K.
Getting a closer look at the VRM heatsinks reveals an aluminum fin design underneath the baseplate for the topmost heatsink. Each heatsink has 7w/Mk thermal pads located underneath for efficient transfer of heat.
The MSI MAG logo is laser-etched on both heatsinks and provides a nice aesthetic for the motherboard.
Expansion slots include three PCI Express (1 Gen 4 x16, 1 Gen 3 x1, 1 Gen 3 x4), and 2 M.2 slots. The M.2 slots are rated to support NVMe PCIe gen4 x4 and Intel Optane series memory.
MSI is using a metallic cover on the sides of the expansion slots which provides protection to some extent. It adds more retention and shearing resistance by reinforcing the slots with metal plates. Aside from adding more protection, they do look really sweet.
The dual M.2 slots are cooled off by the thermal pad and aluminum baseplate cooling. This is part of MSI's M.2 Shield Frozr cooling technology and ensures stable operation for M.2 storage devices. The thermal adhesive has a plastic cover over them which needs to be removed before using them with the storage devices.
The Z690 PCH is housed beneath a large heatsink with the Mortar logo on top of it. The design on the heatsink cover is just for aesthetic.
Storage options include six SATA III ports rated to operate at 6 GB/s. These can support six different storage devices at once. There are also dual USB 3.2 (1x Gen 2 / 1x Gen 1) front panel connectors of which one is right-angled. Many fan headers and jumpers can be found beneath the storage ports.
MSI is using its Audio Boost 5 HD system for audio which is a combination of hardware, software audio solutions. 7.1 CH HD audio with the latest Realtek ALC4080 audio codec.
A bunch of other connectors for chassis power, RGB, and fan headers can be spotted next to them.

MSI is using Intel's Wi-Fi 6E AX210 to power wireless connectivity such as 802.11ax WiFi (2.4G WiFi) and Bluetooth 5.2. In terms of Ethernet, there are single Gigabit Ethernet LAN ports which include an I225V 2.5G Networking chip.
The I/O plate comes with an I/O cover with the same silver color scheme as the board itself. Following is the full list of I/O ports on the MSI MPG Z690 CARBON WIFI motherboard:
- USB 2.0
- 2.5G LAN
- Audio Connectors
- USB 3.2 Gen 2x2 20Gbps Type-C
- Optical S/PDIF Out
