The ASUS PRIME X870-P WIFI, model 90MB1IS0-M0EAY0, is an ATX motherboard built around the AMD X870 chipset and Socket AM5 platform. It supports AMD Ryzen 7000, Ryzen 8000 and Ryzen 9000 Series processors, with capacity for one processor. Designed as a flexible foundation for a high-performance PC, it combines DDR5 memory support, PCIe expansion, multiple M.2 storage connections, RAID functionality, Wi-Fi 7, Bluetooth 5.4, 2.5 Gigabit Ethernet and an extensive selection of USB connectivity.
The motherboard provides four 288-pin DIMM slots and supports a maximum memory capacity of 192GB using DDR5 memory. Memory can operate at a bus clock of up to 4000MHz when overclocked, while dual-channel memory architecture is supported for efficient memory operation. Its memory capabilities also include AMD EXPO technology and ASUS Enhanced Memory Profile, or AEMP. Supported memory configurations include unbuffered on-die ECC, ECC and non-ECC memory.
Expansion options include one PCIe 5.0 x16 slot together with three PCIe 4.0 x16 slots operating in x1 mode, giving the motherboard several options for adding compatible expansion hardware. Storage expansion is provided through four M.2 sockets. Three accept 2280 M.2 Key M devices, while the fourth supports 2242, 2260 and 2280 M.2 Key M formats. The board also includes two SATA-600 connections using 7-pin Serial ATA connectors.
The storage interfaces cover several PCIe generations. One M.2 connection uses PCIe 5.0, two M.2 connections use PCIe 4.0 and one M.2 connection uses PCIe 3.0. RAID 0, RAID 1, RAID 10 and RAID 5 configurations are supported across the specified SATA-600 and M.2 storage interfaces. AMD RAID Xpert2 Technology is also included to provide the motherboard's RAID functionality.
A broad range of external connections is available for peripherals, displays, networking and audio. These include two Thunderbolt 4/DisplayPort/USB4 interfaces, one USB 3.2 Gen 2 port, three USB 3.2 Gen 1 ports and four USB 2.0 ports. An HDMI connection is provided for display output, with onboard graphics functionality requiring a suitable CPU. Wired networking is handled through a 2.5 Gigabit Ethernet LAN connection. The rear connectivity also includes separate mini-jack connections for microphone input, audio line-out and audio line-in.
Additional USB and system connections can be added through the motherboard's internal headers. These comprise one USB-C 3.2 Gen 2 header, two USB 3.2 Gen 1 headers and four USB 2.0 headers. Internal connections also include an audio header, an SPI header and a serial header. Power is supplied through a 24-pin main power connector together with two 8-pin ATX12V power connectors.
Wireless networking is built into the PRIME X870-P WIFI, with support for IEEE 802.11a/b/g/n/ac/ax/be standards and Wi-Fi 7. Bluetooth 5.4 is also supported, while the integrated 2.5 Gigabit Ethernet connection provides the wired networking option. An ASUS Wi-Fi Q-antenna is included with the motherboard for its wireless connectivity.
The integrated audio system provides 8-channel HD Audio and complies with the High Definition Audio standard. For compatible display connectivity, the motherboard also complies with DisplayPort 1.4a. These capabilities sit alongside the HDMI connection and the two combined Thunderbolt 4, DisplayPort and USB4 interfaces.
Cooling features are incorporated throughout the motherboard, including M.2 heatsink support, a VRM heatsink design and a chipset heatsink. ASUS AI Cooling II and ASUS Fan Xpert 4 are also part of the motherboard's cooling and system-management feature set. These technologies are complemented by an 8-layer PCB and a 14+2+1 phase power design.
The motherboard includes a wide selection of ASUS hardware and installation features intended to support system assembly, component management and protection. ASUS EZ DIY and the DIY Friendly Design are joined by Q-DIMM and Q-Slot, while PCIe Slot Q-Release provides another installation-focused feature. M.2 Q-Latch is included for M.2 installation, and the board also incorporates Q-Dashboard, Q-LED Core and ASUS Q-Design. A pre-mounted I/O shield is fitted, alongside an ASUS Stainless Steel Back I/O and ASUS SafeSlot.
Additional hardware protection and power-related technologies include ASUS 5X Protection III, ASUS DIGI+ VRM, ASUS Overvoltage Protection, ASUS ProCool and LANGuard. The motherboard also supports ASUS Aura Sync for compatible lighting integration. BIOS-related hardware provisions include a BIOS FlashBack button and BIOS FlashBack LED.
The PRIME X870-P WIFI uses an AMI BIOS and supports UEFI BIOS, ASUS EZ Flash 3 and ASUS UEFI BIOS EZ Mode. CrashFree BIOS 3 is also included. Wake functions include Wake on LAN and wake on PME, while Preboot eXecution Environment, or PXE, is supported as part of the motherboard's hardware feature set.
The motherboard measures 30.5cm wide by 24.4cm deep and follows the ATX form factor. Its combination of AM5 processor compatibility, AMD X870 chipset technology, DDR5 memory support, PCIe 5.0 expansion, multiple M.2 interfaces, RAID capabilities and extensive wired and wireless connectivity makes it suitable as a configurable platform for gaming, content creation and general computing systems.
Included with the ASUS PRIME X870-P WIFI are two Serial ATA cables, one M.2 rubber package, two M.2 screw packages and an ASUS Wi-Fi Q-antenna. The supplied software selection consists of Armoury Crate, ASUS AURA Creator, ASUS DriverHub, ASUS Fan Xpert 4, TurboV Core and ASUS CPU-Z. Norton 360 Deluxe is supplied as a 60-day trial, while WinRAR is provided as a 40-day trial.
