Focused on providing the best user experience, the MAG series has a simple installation process coupled with a friendly user interface making it the best choice for entry-level gamers. With more cores’ processors, thermal and power design is more important to make sure the temperature keeps lower. MSI extended PWM heatsink and enhanced circuit design ensures even high-end CPU to run at full speed with MSI motherboards. Utilizing 3rd Gen Ryzen processors, MSI B550 motherboards feature the latest Lightning Gen 4 M.2 which is the fastest onboard storage solution on the market with up to 64 Gb/s transfer speed. 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. 2.5Gbps LAN provides incredible data transfer speed faster than general Gigabit LAN. This is a premium solution for demanding users. 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 the same and harmonious traffic bandwidth in an efficient way. MSI LAN Manager automatically classifies and prioritizes the latency-sensitive applications for online games, giving you the best online gaming experience with low latency.
