MSI tend to include their higher end audio on the top-tier motherboards, with the Gaming Pro Carbon AC coming under that umbrella. AudioBoost4 uses Nahimic3 software to help create an even more vibrant audio profile. MSI have also divided the right and left channel into separate PCBs, as well as isolating the entire region of the motherboard to reduce any interference as much as possible.



The rear IO is well featured for a B450 motherboard, coming with a BIOS flashback button, allowing you to flash to the latest BIOS without the need for a CPU, RAM or a GPU. Next up is the PS/2 port, for legacy support of keyboards and mice, as well as a pair of USB 2.0 ports which are still perfectly adequate for keyboards and mice, even with a 1000Hz polling rate or RGB lighting.

Due to the possibility of using an AMD APU, there’s a DisplayPort and HDMI port for connecting up high resolution monitors.

The two gold ports are for antenna connections, for the Intel WiFi and Bluetooth chip.

Carrying on to the right, the first red stack is a pair of USB 3.0 ports and the Intel Gigabit LAN port.

Then we get to the high-speed USB connectivity, with the Type A and Type C USB 3.1 Gen. 2 ports.

Last up, audio, with 7.1 audio support, or gold plated SPDIF out for digital audio.
