MSI B350 Tomahawk Plus
Armored Military Styling Meets Rock-Solid AM4 Reliability
Overview
How It Works
Power Delivery Regulation
Incoming power from the ATX power supply is refined through a multi-phase Digital VRM architecture, delivering stable voltages directly to the AM4 socket for the CPU and integrated memory controller.
Data and Signal Routing
High-speed traces and PCIe Gen 3 pathways route data between the processor, DDR4 memory slots, and high-bandwidth storage devices like the onboard Turbo M.2 slot with minimal latency.
Thermal and Lighting Control
Onboard PWM fan headers and Mystic Light LED controllers dynamically adjust cooling performance and chassis illumination based on real-time hardware telemetry monitored by the Click BIOS 5 environment.

Setup Tips
Update the BIOS First
If you are installing a newer generation Ryzen processor, update the BIOS to the latest version before finalizing your hardware configuration.
Enable A-XMP in BIOS
Navigate to the UEFI settings upon first boot and enable A-XMP to ensure your DDR4 RAM runs at its rated high frequency rather than default JEDEC speeds.
Utilize EZ Debug LEDs for Troubleshooting
Pay attention to the onboard diagnostic LEDs if your system fails to post on the first attempt to instantly identify faulty memory or seating issues.
Connect Fans to PWM Headers
Plug your case fans into the designated PWM headers to take full advantage of MSI Total Fan Control curves within the Click BIOS 5 utility.
