MSI Mystic Light RGB Lighting

The right side of this motherboard features built-in LED lighting. Choose from over a million colors and a variety of lighting effects to fit your style. You can also sync it with other MSI Mystic Light-compatible hardware and peripherals to complete your build.

Cooling

For cooling, this motherboard has six fan headers that support both DC and PWM modes, which allow you to manually or automatically adjust speeds within BIOS or a third-party software, so you can find your preferred balance between cooling and noise.

Storage

Aside from standard SATA ports, the B450 Tomahawk also has a single M.2 slot, which is PCIe 3.0 x4 compatible for speeds of up to 32 Gb/s when used with an appropriate drive. Additionally, you can use MSI X-Boost and AMD STOREMI to help optimize your drives' storage and performance.

Audio

MSI Audio Boost consists of both hardware and software additions that are designed to provide you with a high-quality listening experience. The left and right channels are built on separate PCB layers, De-Pop Protection prevents loud popping noises, an EMI-shielded audio processor ensure clean stereo and surround sound, and a dedicated headphone amplifier automatically detects the optimal impedance for your headphones. For gaming, Nahimic 3 provides you with virtual surround sound with an in-game overlay that displays where noises are coming from.
