Maxsun has launched three new B850 microATX motherboards for the AM5 platform supporting AMD Ryzen processors: MS-B850M I-CAFE, B850M-P WIFI, and B850M-B WIFI.

The MS-B850M I-CAFE measures 245 x 210 mm and features two DDR5 DIMM slots supporting up to 128 GB at DDR5-8000 OC. It includes one PCIe 5.0 x16 and one PCIe 4.0 x4 slot, two M.2 slots, two SATA ports, 2.5 GbE, and HDMI 1.4. It lacks Wi-Fi but has four USB 5 Gbps and two USB 2.0 Type-A rear ports.

The two Challenger models share most specs: PCIe 5.0 x16 and PCIe 4.0 x4 slots, two M.2 slots, two SATA ports, Wi-Fi 6 and Bluetooth 5.2 via MediaTek MT7902, 2.5 GbE, a USB-C 20 Gbps front header, and four USB 5 Gbps plus four USB 2.0 rear ports. The B850M-P WIFI is larger at 245 x 245 mm with four DIMM slots for up to 256 GB DDR5. The B850M-B WIFI is 245 x 215 mm with two slots for 128 GB. Both offer HDMI 2.0 and dual DisplayPort 4K at 60 Hz.

All three use a Realtek ALC897 audio codec. Pricing and availability for the full lineup have not been officially announced, though the MS-Challenger B850M-P WIFI has appeared listed in the Chinese market at CNY 799 (around $119).
