ASUS Prime B850-Plus WiFi

The Prime B850-Plus WiFi is ASUS's value-focused ATX board for the AM5 platform, giving budget-minded Ryzen 9000/8000/7000 builders a full-size board with PCIe 5.0 GPU support and Wi-Fi 6E, without the premium pricing of the TUF or ROG lines.

Power delivery runs through ASUS's DIGI+ VRM with Dr. MOS power stages as part of the 5X Protection III design suite; ASUS does not publish an exact phase count for this board, but reviewers consistently rate it sufficient for any Ryzen 9000 non-X3D chip at stock clocks. Four DDR5 DIMM slots support up to 256GB total capacity, with AMD EXPO and AEMP profiles enabling overclocked speeds up to 8000+ MT/s on Ryzen 9000/8000/7000 processors. Expansion includes a PCIe 5.0 x16 primary slot, a PCIe 4.0 x16 slot running at x8/x4, and two PCIe 3.0 x16 slots wired at x1 for legacy cards. Storage covers three M.2 slots (PCIe 5.0 x4, PCIe 4.0 x4, and PCIe 4.0 x2) plus four SATA 6Gb/s ports. A 2.5GbE Realtek LAN controller with ASUS LANGuard protection handles wired networking, and Wi-Fi 6E 2x2 covers the 2.4/5/6GHz bands. Audio uses a Realtek 7.1 surround codec. Against the Gigabyte B850M AORUS STEALTH ICE in this catalog, the Prime B850-Plus WiFi trades the micro-ATX form factor for full ATX and adds a third PCIe 3.0 slot, making it the better pick for builders who want more expansion room in a standard case.
