AI Networking II

AI Networking II combines intelligent technologies to continuously optimize network performance, provide trustworthy and seamless connectivity, and unleash the full speed of WiFi 7*.

*Features may vary by model.

PCIE SLOT Q-Release Slim

With PCIe Slot Q-Release Slim, simply tilt the card toward the latching mechanism to automatically unlock it from the PCIe slot. This makes upgrades and maintenance easier than ever before. Users will no longer need to fiddle with a tricky latch or even press a button to release their graphics card from the slot.

M.2 Q-RELEASE

The M.2 heatsink features a convenient switch* to quickly remove it, eliminating the need for tiny screws during SSD installation. Its strong locking mechanism also provides a snug contact surface, helping to ensure reliable heat dissipation for your SSD.*Switch may be a lever or button, depending on motherboard model.

NEW M.2 Q-LATCH

The new Q-Latch design allows for tool-free installation or removal of M.2 SSDs with just one press.

PCIE 5.0

Fully embracing the new standard, the Strix B850-A offers end-to-end PCIe 5.0 support. The topmost x16 expansion slot is Gen 5-ready, and is protected with a SafeSlot retention bracket to bear the weight of the latest graphics cards. One of the onboard M.2 slots is geared for blistering 16 GB/s read and write speeds thanks to its PCIe 5.0 interface, while all the rest can deliver still-impressive 8 GB/s transfers. Every M.2 slot is covered with substantial heatsinks to dispatch the heat of next *-gen drives.

Power Design

POWER ARCHITECTURE

The VRM features 14+2+2 power stages, each rated to handle 80 amps.

2. ALLOY CHOKES AND DURABLE CAPACITORS​

Hi-end chokes and durable capacitors are engineered to resist extreme temperatures, enabling performance that exceeds industry standards.

3. EIGHT-LAYER PCB​

A multi-layered printed circuit board design quickly dissipates heat around the voltage regulators to improve overall system stability and provide the CPU with more overclocking headroom.​

DDR5 Strength

For those who want to fly past stock DDR5 speeds, the Strix B850-A is primed and ready for enthusiast-grade kits, courtesy of vast AMD Extended Profiles for Overclocking (EXPO) support. Seasoned veterans can further tweak performance via the extensive array of settings in the UEFI.

COOLING​

1. VRM HEATSINK ARRAY

Two VRM heatsinks, one expanding underneath the I/O shroud, provide ample surface area and mass to handle the power needs of high-performance AMD Ryzen 9000 Series processors .

2. High-conductivity Thermal Pads

High-quality thermal pads are utilized between power stages and heatsinks, helping to improve heat transfer and reduce VRM operating temperatures.

3. M.2 BACKPLATE

An integrated backplate helps ensure that high-performance drives can deliver peak performance, even when airflow is restricted.

4. M.2 HEATSINKS

Heatsinks cover every slot to help keep onboard NVME SSDs at optimal temperatures for consistent performance and reliability.

NETWORKING

1. WIFI 7

The revolutionary WiFi 7 is faster than standard WiFi 6*, thanks to tech like 160 MHz channels** on the 6GHz band and 4K QAM*. Multi-Link Operation (MLO) provides a more stable WiFi connection and lower latency, unlocking the realms of the unknown in gaming, streaming and industrial IoT.

* WiFi 7 features require onboard WiFi chipset, WiFi AP, and WiFi 7-supported operating systems to support the corresponding features.

** Specifications vary by model.

2. Intel 2.5Gb Ethernet

Onboard Intel 2.5Gb Ethernet gives your wired connection a boost, with speeds that are 2.5 times faster than standard Ethernet connections for speedy file transfers, low-latency gaming, and high-res video streaming.
