Product Features
Broad AMD Ryzen Support: Build around Socket AM4 with support for AMD Ryzen 5000 Series, 5000 G-Series, 4000 G-Series, and 3000 Series desktop processors. This flexibility makes it easier to match the board to your current CPU or plan a future upgrade. Pairing the right processor lets you focus on performance without changing your platform.
Fast Expansion And Storage Paths: Enjoy a lightning fast experience with a PCIe 4.0 slot and Lightning Gen4 x4 M.2 support. This setup helps you take advantage of high-speed PCIe devices where supported by the installed processor. With two M.2 slots available, you can organize storage builds more cleanly while keeping the system responsive.
EZ DIY Setup And Troubleshooting: Simplify the build process with EZ Debug LED and EZ Mounting. When something is not quite right during assembly, the debug LEDs help you identify issues faster. That means less guesswork and more time getting your PC up and running.
Audio And Software Experience: Audio Boost is designed to reward your ears with studio-grade sound quality for everyday listening and gaming. MSI Center brings MSI exclusive tools together in a user-friendly interface, helping you manage supported features from one place. This combination makes the system feel more polished once everything is installed.
