ATX motherboard with silver heatsinks and black PCB

ASUS

ASUS ROG STRIX B850-A GAMING WIFI S AMD motherboard

SKU CH-3FDP-BQC5F

ATX board for AMD Ryzen 7000/8000/9000 CPUs with 16+2 70A power stages, PCIe 5.0 x16, dual M.2, WiFi 6E and 2.5G LAN

  • CPU Socket TypeAM5
  • ChipsetAMD B850
  • Stable overclocking with 16+2 power stages rated at 70A
  • Next-gen GPU and storage speed via PCIe 5.0 x16 and dual M.2 slots
  • Cooler VRM and M.2 operation through stacked-fin heatsinks and thermal pads
  • Fast wired and wireless networking with 2.5G LAN and WiFi 6E
  • High-speed USB 3.2 Gen 2x2 Type-C at 20Gbps plus USB4 header support

AM5 Platform for Ryzen 7000 8000 9000

This ATX motherboard uses the AMD B850 chipset and AM5 socket to support Ryzen 7000 8000 9000 series processors. A 16+2 power stage design rated at 70A with alloy chokes and durable capacitors delivers stable current for overclocking. It targets builders who want a high-performance foundation for gaming or content creation.

PCIe 5.0 DDR5 Connectivity and Thermal

One PCIe 5.0 x16 SafeSlot and two M.2 slots — one PCIe 5.0 x4 and one PCIe 4.0 x4 — provide fast storage and graphics bandwidth. DDR5 memory slots are optimised for high-speed kits. VRM heatsinks with stacked fins and M.2 heatshields with thermal pads handle heat, while multiple hybrid fan headers including AIO pump support keep airflow flexible.

WiFi 6E 2.5G LAN USB 20Gbps Upgrade

Rear USB 3.2 Gen 2x2 Type-C at 20Gbps, front-panel USB 3.2 Gen 1 Type-C header and USB4 support via header expand peripheral options. WiFi 6E and 2.5G LAN with LANGuard improve network reliability over older boards. The jump is worth it when moving from an earlier chipset that lacks PCIe 5.0 graphics and storage lanes or 20Gbps USB.

Perguntas sobre este artigo

What PCIe standard does the top x16 slot use and what bandwidth does it provide?

The primary slot is PCIe 5.0 x16 SafeSlot, giving up to 5.0 x16 bandwidth for a graphics card.

What are the physical dimensions and mounting points of this board?

ATX form factor with standard mounting holes; four M.2 slots and a front-panel USB 3.2 Gen 1 Type-C header require matching case cut-outs.

How do I install a CPU on the AM5 socket and what step is often missed?

Lift the retention arm, align the triangle markers, seat the processor gently, lower the arm, then apply thermal paste before mounting the cooler.
