AM5 Platform Board

The ASUS X870 AYW GAMING WIFI W is an ATX motherboard built on the AMD X870 chipset for Ryzen 7000, 8000 and 9000 series processors. It targets enthusiasts who want a white-themed build with high-speed connectivity and robust power delivery.

DIY-Friendly Installation

A pre-mounted I/O shield, PCIe Slot Q-Release and M.2 Q-Latch simplify the build process. BIOS FlashBack allows firmware updates without a CPU installed. The PCIe 3.0 x16 slot shares bandwidth with two SATA ports, so using that slot disables those SATA connections unless the BIOS is adjusted.

High-End Gaming and AI Workloads

The 12+2+1 80A DrMOS power stages, DDR5 support up to 8000+ MT/s and PCIe 5.0 x16 plus M.2 slots suit demanding gaming and AI tasks. Builders needing more than four SATA ports or legacy PCIe 3.0 expansion should consider alternative boards.

Highlights

  • Supports Ryzen 7000, 8000 and 9000 series CPUs on AM5 socket
  • 12+2+1 80A DrMOS power stages with 8-layer PCB for stable delivery
  • PCIe 5.0 x16 slot plus PCIe 5.0 M.2 for fastest graphics and storage
  • Wi-Fi 6, 2.5Gb LAN and USB4 40Gbps Type-C for high-speed connectivity
  • Four DDR5 slots up to 8000+ MT/s with AMD EXPO and ECC support

Questions about this item

How do I confirm the 12+2+1 80A DrMOS power delivery is operating correctly after assembly?

Enter the BIOS and open the hardware-monitor page; it reports real-time CPU Vcore, VRM temperature and phase current for each of the 12+2+1 power stages, so you can verify stable readings under load.

What accessories are included and which items must be purchased separately for a complete build?

The box contains the ATX motherboard with pre-mounted I/O shield, SATA cables, M.2 Q-Latch screws, Wi-Fi 6 antenna, driver disc and manual; you still need an AM5 Ryzen 7000/8000/9000 processor, DDR5 memory, graphics card, storage drives and an ATX power supply.

Which M.2 slot should I choose for a PCIe 5.0 x4 drive versus a PCIe 4.0 x4 drive?

Use the M.2_1 slot (Key M, 2280) for a PCIe 5.0 x4 drive when paired with a Ryzen 9000 or 7000 CPU; use the M.2_2 slot (Key M, 2242/2260/2280) for a PCIe 4.0 x4 drive.
