Description
Expert Features
- Modern AMD AM5 Platform : The AMD B850 chipset and Socket AM5 support compatible Ryzen 9000, 8000 and 7000 Series desktop processors. Its micro-ATX footprint suits space-conscious productivity, creator and gaming builds.
- Wi-Fi 7 with MSI EZ Antenna : Built-in Wi-Fi 7 delivers next-generation wireless connectivity, joined by Bluetooth 5.4. The real MSI EZ Antenna attaches to the motherboard’s wireless connectors without tedious screw-on rotation and can be positioned for a cleaner desktop setup. Features and 6 GHz availability depend on region, router, operating system and configuration.
- Faster Wired Networking: 5G LAN : The onboard Realtek 8126VB 5 Gigabit LAN controller provides a high-bandwidth wired link for fast file transfers, busy networks and low-latency online work, when paired with compatible network equipment.
- Four DDR5 Slots, Up to 256GB : Four DDR5 UDIMM slots support dual-channel memory and AMD EXPO profiles. MSI specifies overclocked speeds reaching 8200+ MT/s with select Ryzen 9000 Series configurations, compatible memory kits and BIOS settings.
- PCIe 5.0 Graphics and Gen5 SSD Support : The reinforced primary PCIe x16 slot supports PCIe 5.0 with qualifying Ryzen 9000/7000 processors. Storage options include a PCIe 5.0 x4 M.2 slot, a PCIe 4.0 x4 M.2 slot and four SATA 6Gb/s ports; PCIe generations and link widths can vary with the installed processor.
- Efficient, Cooled Power Delivery : MSI’s Direct 8+2+1 phase power design, 60A Vcore Smart Power Stages, 8+4-pin CPU power connections, extended heatsinks and six-layer PCB with 2oz thickened copper are engineered for a stable platform under demanding workloads.
- Simplified Building and Maintenance : EZ M.2 Shield Frozr II, EZ M.2 Clip II and EZ PCIe Clip II ease installation and upgrades. A pre-installed I/O shield, Flash BIOS Button, Clear CMOS Button and diagnostic LEDs make setup and troubleshooting more convenient.
- Versatile High-Speed USB and Display I/O : The back panel carries three 10Gbps USB-A ports, two 10Gbps USB-C ports and three 5Gbps USB-A ports. HDMI 2.1 and DisplayPort 1.4 each support up to 4K/60Hz with a CPU that includes integrated graphics.
