Placa base Sapphire PURE B850M WIFI Micro ATX — AMD B850, socket AM5, DDR5 hasta 8000 MHz, 4 DIMM, Wi‑Fi 6, 2,5 Gb LAN, 2× M.2, PCIe 5.0 x16

Sapphire PURE B850M WIFI is a Micro ATX motherboard for AMD Socket AM5 processors, designed for AMD Ryzen 7000 series CPUs. It is built on the AMD B850 chipset and supports DDR5 memory up to 8000 MHz across four DIMM slots in dual-channel configuration, with a maximum capacity of 256 GB. The board includes integrated Wi‑Fi 6 and Bluetooth 5.3, Realtek 2.5 Gb Ethernet, 5.1-channel audio via Realtek ALC897, two M.2 slots (PCIe 5.0 and PCIe 4.0), SATA III connections for multiple drives, USB Type-C and several USB Type-A ports, and a PCIe 5.0 x16 slot for a discrete graphics card.

Advantages

The Micro ATX form factor offers a compact layout while retaining modern connectivity such as PCIe 5.0 x16, dual high-speed M.2 slots, and DDR5 support up to 8000 MHz. Integrated Wi‑Fi 6 and Bluetooth 5.3 provide wireless networking out of the box, and the Realtek 2.5 Gb LAN controller delivers faster wired connections. Multiple USB ports including USB 3.2 Gen 2 Type-A and Type-C, plus support for up to six storage drives, make the board versatile for both gaming and productivity builds.
