Maxsun has released 3 new Micro ATX motherboards based on the AMD B850 chipset for the Socket AM5 platform. The new lineup includes the MS B850M I Cafe alongside 2 Challenger models that feature Wi Fi 6 and memory speeds reaching 8000 MT/s. The MS Challenger B850M P WiFi is currently available first in the Chinese domestic market for 799 RMB.
Maxsun built the MS B850M I Cafe specifically for internet gaming centers and continuous uptime environments. The board features the signature red and black aesthetic common to the brand's commercial product line. Power delivery relies on an 8+2+1 phase layout using 50A DrMOS modules to handle modern AMD processors. Expansion options include 2 PCIe slots and 2 M.2 solid state drive slots for fast storage. Network connectivity is handled by a 2.5GbE LAN controller, and hardware troubleshooting is supported by distributed debug lights placed directly on the board.
The two other additions belong to the Challenger product family, offering nearly identical base hardware with a difference in physical width. The MS Challenger B850M P WiFi provides 4 memory slots on a standard width board, while the MS Challenger B850M B WiFi uses a narrower layout with 2 memory slots. Both motherboards support DDR5 memory overclocking up to 8000 MT/s and use a 6+2+1 phase power delivery design built with 60A SPS DrMOS modules.
Expansion covers 3 PCIe slots including Gen5 x16, Gen4 x4, and Gen3 x1 bandwidth. Storage connectivity includes 2 M.2 slots with support for PCIe Gen5 x4 and PCIe Gen4 x4 solid state drives, plus 2 SATA 6Gbps ports. Audio processing runs through a Realtek ALC897 codec, and high speed connectivity is supported by 2.5GbE LAN, Wi Fi 6, and a front USB C port running at 20Gbps.
