The AMD Sapphire PULSE B850M WIFI is a Micro-ATX motherboard built on the AMD B850 chipset, designed for Socket AM5 processors including the AMD Ryzen 7000, 8000, and 9000 Series. With support for up to 192GB of DDR5 memory across four DIMM slots in dual-channel configuration and overclocked speeds up to 7600 MHz, this board delivers a solid foundation for high-performance builds. Its compact 235 x 244 mm form factor makes it suitable for space-conscious system builds without sacrificing functionality.
Connectivity and Storage
The PULSE B850M WIFI offers extensive connectivity options, including two M.2 slots — one supporting PCIe 5.0 and one PCIe 4.0, both up to 2280 in size — alongside four SATA III connectors for additional storage. A single PCIe x16 Gen 4 slot accommodates a dedicated graphics card. For peripheral connectivity, the board provides eight USB 2.0 ports, three USB 3.2 Gen 1 Type-A ports, one USB 3.2 Gen 1 Type-C port, as well as HDMI and DisplayPort outputs for display flexibility.
Wireless and Audio Capabilities
Wireless connectivity is handled by Wi-Fi 6 (802.11ax) with two antenna jacks, complemented by Bluetooth 5.3 for versatile wireless communication. Wired networking is supported via a Realtek RTL8125BG 2.5GbE LAN controller. Audio is managed by a Realtek ALC897 chip delivering 5.1-channel output, with three headphone outputs and a front panel audio connector. Three chassis fan headers and a CPU fan connector complete the thermal management options.
