FAST AND FUTURE-READY STORAGE

MSI B550 motherboards support all the latest storage standards, which allows users to connect any ultra-fast storage device. Higher efficiency makes your work easier.

OPTIMIZED STORAGE DESIGN

MEG B550 UNIFY series motherboard features exclusive onboard quadruple M.2 connectors for the maximum storage performance. The Industry leading design maximizes bandwidth to fully utilize high-end storage devices, provides multiple configurations for demanding gamers and power users.

CONNECTIVITY

MSI motherboards are built with a variety of connectors to satisfy gamers. Enhanced audio, advanced LAN networking capabilities, USB and Mystic Light turn any gaming experience into an immerse one.

HIGH-BANDWIDTH AND LOW-LATENCY NETWORK

2.5Gbps LAN provides incredible data transfer speed faster than general Gigabit LAN. This is a premium solution for demanding users.

SURFACING WITH THE REAL MU-MIMO TECHNOLOGY

The WIFI 6 adopts the latest OFDMA and two-way MU-MIMO technologies and could provide up to 4X network capacity and efficiency in the high signal density environment. Comparing to the WIFI 5, which can only send the data packet to one device at a time on each channel, the WIFI 6 could combine the packet, separate to several devices and allow signals from the different devices bundled together. This new technology provides all the devices in the same network environment with same and harmonious traffic bandwidth in an efficient way.

OPTIMIZE ONLINE GAMING TRAFFIC FOR LOWER LATENCY!

MSI LAN Manager automatically classifies and prioritizes the latency-sensitive applications for online games, giving you the best online gaming experience with low latency.
