MSI is already one of the most prolific providers of Ryzen-ready motherboards, but over the weekend the company launched four more ATX boards. The X370 Gaming Pro Carbon-AC, X370 Gaming Plus, B350 Gaming Plus, and B350 Krait Gaming all belong to the company's Performance Gaming family, marking them as enthusiast-class hardware with an emphasis on stylish design.

MSI says the X370 Gaming Pro Carbon-AC is the new flagship for its Socket AM4 Performance Gaming lineup. This board is fundamentally unchanged from the standard X370 Gaming Pro Carbon, except that MSI now throws an Intel Wi-Fi-plus-Bluetooth adapter in the box. With that said, this high-end offering sports a trio of PCIe 3.0 x16 slots, a pair of USB 3.1 ports, and a pair of M.2 sockets. Realtek-powered eight-channel audio and an Intel Gigabit Ethernet controller complement the package. As befits a top-tier model, the X370 Gaming Pro Carbon offers onboard RGB LED lighting.

Compared to the flagship model, the B350-chipset version of the Gaming Pro Carbon sacrifices two SATA ports, an M.2 socket, and SLI support. This board otherwise retains its bigger brother's accoutrements, including the USB 3.1 ports.

The X370 Gaming Plus and B350 Gaming Plus bear the same edgy black-and-red color scheme common to most of MSI's gaming hardware, and are very similar in appearance as well as function. Almost all of the differences between the two boards come down to their chipsets' feature set.

The X370 Gaming Plus comes with three PCIe x16 slots, six 6 Gbps SATA ports, and a pair of USB 3.1 ports. Meanwhile, the B350 Gaming Plus only has a pair of PCIe x16 slots, four SATA ports, and no USB 3.1 ports Both boards use Realtek controllers to provide LAN and audio functionality, and have a single PCIe 3.0 x4 M.2 socket. The B350 Gaming Plus does offer some connectivity that its bigger brother doesn't have: two legacy PCI slots. Neither of these boards offers LED lighting.

Finally, the B350 Krait Gaming is a little bit fancier than the B350 Gaming Plus above. The Krait is similar to the Gaming Plus in its basic layout, meaning you get two PCIe x16 slots, four DDR4 DIMM slots supporting up to 3200 MT/s, four 6 Gbps SATA ports, and an M.2 socket with four lanes of PCIe 3.0 connectivity. Since the B350 chipset doesn't offer USB 3.1 support, MSI added an ASMedia controller powering USB 3.1 Type-A and Type-C ports at the rear panel. Lastly, there's backside white LED lighting to provide an ambient glow behind your motherboard.

All five boards support for MSI's Mystic Light Sync via onboard RGB LED control headers. MSI didn't announce any prices for the new boards or say when they'll be available. We wager that they'll be showing up at e-tailers any moment now, though.
