ASUS PRIME X870-P, AMD X870, Socket AM5, ATX
Overview
ASUS Prime series motherboards are expertly engineered to unleash the full potential of AMD Ryzen™ 9000 series processors. Boasting a robust power design, comprehensive cooling solutions and intelligent tuning options, the PRIME X870-P provides users and PC DIY builders with a range of performance optimisations via intuitive software and firmware features. It is designed to be Advanced AI PC-ready, offering the power and connectivity needed for demanding AI applications.
Power Design & Performance
Robust 14+2+1 Power Stage Design
Stable power is crucial for maximising the performance of AMD processors. The PRIME X870-P features 14(80A) + 2(80A) + 1(80A) power stages that integrate high-side and low-side MOSFETs and drivers into packages rated for up to 80 amperes each. This configuration ensures optimal power delivery, efficiency, stability and performance for both current and future AMD processors.
Memory & Storage
Enhanced DDR5 Performance
The PRIME X870-P maximises the potential of your DDR5 modules, from entry-level to extreme-speed kits. For entry-level modules without EXPO™ support, ASUS Enhanced Memory Profile (AEMP) automatically detects memory chips and provides optimised profiles for enhanced performance. For those looking to surpass stock DDR5 speeds, the board offers extensive AMD Extended Profiles for Overclocking (EXPO™) support and a wide array of UEFI settings for further performance tweaks. Supports up to 192 GB across 4 DIMM slots, dual-channel, up to 8000 MHz, ECC & Non-ECC unbuffered.
Four M.2 Slots (up to 128 Gbps)
PRIME X870-P offers a total of four M.2 slots: one supporting data-transfer speeds of up to 128 Gbps via PCIe 5.0, two supporting 64 Gbps via PCIe 4.0, and one supporting PCIe 3.0. This enables quicker boot-up and app load times with OS or application drives. Paired with 2x SATA III ports and RAID 0, 1, 5, 10 support across up to 6 storage drives.
Connectivity
USB4 Gen 2×2 (40 Gbps) Type-C® Ports
Two rear USB4 ports each deliver up to 40 Gbps of bi-directional bandwidth for the latest super-speed devices and drives. Both ports can be used for up to two external 4K displays.
PCIe 5.0 Slot
The primary x16 slot runs at PCIe 5.0, doubling data transfer speeds compared to PCIe 4.0, with backward-compatible CEM connectors and support for previous PCIe versions. Additional slots include 2× PCIe 4.0 x16.
2.5 Gigabit Ethernet
Realtek 2.5GbE wired networking for fast, reliable connectivity. No Wi-Fi onboard.
Rear I/O Summary: 4× USB 2.0, 3× USB 3.2 Gen 1 Type-A, 1× USB 3.2 Gen 2 Type-A, 2× USB4 Gen 2×2 Type-C, 1× HDMI 2.1, 1× DisplayPort 1.4a, 1× RJ-45 (2.5GbE), Line-in, Mic-in.
Cooling
Cooler by Design
The PRIME X870-P is engineered with multiple onboard heatsinks and an array of hybrid fan headers (1× CPU fan, 4× chassis fan) to help ensure your rig stays cool and stable under intense workloads. Cooling is passive on the chipset heatsink.
ASUS Fan Xpert 4
Comprehensive control over fans and AIO coolers. Auto-Tuning mode configures settings with one click, while Extreme Quiet mode reduces fan speeds for silent operation during light tasks. Controls are also available via the UEFI BIOS.
AI Cooling II
Optimised thermals and reduced noise via dynamic adjustment of fan speeds based on CPU temperatures.
Design & Aesthetics
Black PCB with Aura Sync RGB lighting. Three addressable Gen 2 RGB headers detect LED counts on compatible devices and automatically adjust lighting effects. Customise via Armoury Crate software. Form factor: ATX (305 × 244 mm).
