ASUS Prime X870-P WiFi (AM5/AMD X870/ATX/Four M.2 Slots/Wi-Fi 7/PCIe 5.0) Review
The Prime X870-P WiFi gives value-focused AM5 builders X870-level chipset features, including PCIe 5.0 GPU and M.2 support, at a lower price than ASUS's TUF or ROG X870 boards.
ASUS does not publish an exact phase count for this board, though it is commonly reported in reviews as a 14+2+1 design using 80A DrMOS stages, sufficient for Ryzen 9000 non-X3D chips at stock clocks. Four DDR5 DIMM slots (ECC and non-ECC, unbuffered) support up to 256GB total, with AMD EXPO enabling overclocked speeds up to 8000+ MT/s. Expansion includes a PCIe 5.0 x16 primary slot (PCIe 4.0 on Ryzen 8000 APUs) and three additional PCIe 4.0 x16 slots running at x1. Storage covers four M.2 slots: one PCIe 5.0 x4, two PCIe 4.0 x4, and one PCIe 3.0 x2. A Realtek 2.5Gb Ethernet controller handles wired networking, paired with 2x2 Wi-Fi 7 (802.11be). Audio uses a Realtek 7.1 surround codec. Against the ASUS TUF Gaming X870-Plus WiFi in this catalog, the Prime X870-P WiFi trades TUF's military-grade component certification for a lower price while matching its PCIe 5.0 GPU and Wi-Fi 7 support.
