AMD AM5 platform bundle

This package pairs an ASUS ROG STRIX X870-A GAMING WIFI S motherboard with an AMD Ryzen 7 9800X3D processor. The board uses the X870 chipset and AM5 socket, supporting Ryzen 7000, 8000 and 9000 series CPUs. The included 9800X3D delivers 8 cores and 16 threads based on Zen 5 architecture with a 5.2 GHz boost clock.

AI-assisted tuning and storage layout

ASUS-exclusive AI Overclocking, AI Cooling II, AI Networking and DDR5 AEMP automate performance and stability adjustments. The board also provides Dynamic OC Switcher, Core Flex, Asynchronous Clock and PBO Enhancement for manual control. Storage includes two PCIe 5.0 M.2 slots and two PCIe 4.0 M.2 slots, each fitted with substantial cooling.

Power delivery and connectivity headroom

A 16+2+2 power stage design rated at 90A per stage with dual ProCool II connectors supports heavy multi-core workloads. WiFi 7 and USB4 provide high-throughput wireless and wired connectivity. The platform earned a CES 2025 Innovation Award Honoree designation for its engineering.

Questions about this item

Will the 16+2+2 power stages rated for 90A each need active cooling upgrades later?

The 16+2+2 power solution uses dual ProCool II connectors, alloy chokes and durable capacitors designed for multi-core processors; no maintenance or replacement of the VRM components is expected under normal use.

What thermal limit appears first when the Ryzen 7 9800X3D runs at 5.2 GHz all day?

The CPU's 5.2 GHz boost is governed by its own thermal design; the motherboard's substantial M.2 heatsinks and AI Cooling II manage platform heat, but the processor's junction temperature remains the first limiting factor.

How loud or hot does the board get with all four M.2 slots populated under sustained load?

Two PCIe 5.0 and two PCIe 4.0 M.2 slots each have substantial cooling solutions; AI Cooling II adjusts fan curves automatically, keeping noise and temperatures controlled during continuous operation.
