MSI B450 Gaming Pro Carbon AC

The MSI B450 Gaming Pro Carbon AC sits as MSI’s premier and flagship B450 chipset motherboard and has a strong focus on gaming but moves away from the conventional MSI Gaming red and black theme. The B450 Gaming Pro Carbon AC also uses a variety of premium controllers and chips including the Realtek ALC1220 audio codec, an Intel 9260 dual-band 802.11ac 2T2R Wi-Fi adapter and an Intel I211-AT Gigabit LAN networking chip.

As mentioned, the B450 Gaming Pro Carbon AC moves away from the traditional gaming theme usually seen from MSI, and instead the carbon namesake features an all-black PCB with the bottom left quadrant having a grey lined pattern rising towards the heatsinks and passed the PCIe slots. Both the power delivery and chipset heatsink have a definitive carbon themed styling which blends in with the rest of the board to create a stylish look. The board also has two dedicated RGB zones with the first emanating from the right and side behind the 24-pin ATX power connector, with the second coming from the chipset heatsink. To expand on this, MSI has included a total of three RGB headers with two having support for 5050 RGB LED strips with a maximum power of 12 V, and the last supporting addressable RGB strips up to a power of 5 V.

The board conforms to the standard ATX form factor and has a full-length PCIe 3.0 x16 slot, a full-length PCIe 2.0 x4 slot and three PCIe 2.0 1x slots. The B450 Gaming Pro Carbon AC has a total of four memory slots supporting up to DDR4-3466 with a total of 64 GB system memory supported. A total of six SATA right angled ports and two M.2 slots with one offering PCIe 3.0 x4/SATA support, and the other allowing for just PCIe 2.0 x4 supported drives. 

On the rear panel, the B450 Gaming Pro Carbon AC has one USB 3.1 10 Gbps Type-C, one USB 3.1 10 Gbps Type-A, two USB 3.1 5 Gbps Type-A and two USB 2.0 ports. Delivering audio through the six 3.5mm audio jacks and S/PDIF optical output is the Realtek ALC1220 audio codec, with the single LAN port taking direction from an Intel I211-AT Gigabit chip and the Wi-Fi featuring Wave 2 2T2R capability due to the Intel 9260 Wi-Fi module. Finishing off the rear panel is a clear CMOS switch and a P/S2 keyboard and mouse combo port.

While none of the pricing on MSI B450 models has been announced prior to launch, the B450 Gaming Pro Carbon AC is expected to retail for around $149.99.

    Gavin, you made a table that shows B350 and A320 don't support PB2 and XFR2. This is incorrect. Raven Ridge (2400G, 2200G, 2X00U) work without a problem on these boards. Yes, Raven Ridge has PB2 and XFR2 from day one. AMD advertised it when they launched RR last year.

    It's not natively enabled from launch - it requires a BIOS update which not all vendors on all boards have provided. The CPUs work sure, but not all features of the CPUs will work in all products.

    PB2 and XFR work on A320 as well.

    If you buy the boards directly from there amazon store or on there website they should be Stock updated.

    Please fix your charts. PCIe should be 3.0 not 2.0
  • Ian Cutress - Tuesday, July 31, 2018 - link

    The Chipset supports PCIe 2.0 lanes. PCIe 3.0 lanes come from the CPU.

    yeah but the 2nd x16 slot is also from the cpu and thus 3.0, you can even choose to make it a 8x slot in the bios by downgrading the first slot to 8x.

    The review incorrectly states the second full length slot is only 2.0.

    StoreMI can work on 300-series motherboards but comes with an additional fee (I don't think it's BIOS dependent).

    The systems support 10 GbE, if you buy the cards. Yes it's picking hairs, but we're speaking native support.

    What does 10GbE have to do with StoreMI?!
