ROG STRIX B850-A Gaming WiFi
Elevate your build with the ROG Strix B850-A Gaming WiFi. Featuring a sleek white PCB and support for AMD Ryzen™ 9000 Series processors, this motherboard delivers the power and connectivity needed for advanced AI applications. With DDR5 support, full PCIe 5.0 capabilities, USB 20Gbps port, and WiFi 7, it's the ultimate blend of style and performance.
PBO ENHANCEMENT
AMD Precision Boost Overdrive (PBO) pushes the CPU current and voltage budget to opportunistically increase performance. By aggressively tuning the PBO parameters, AMD's algorithm can leverage the motherboard's robust power solution to ramp up performance even higher.
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.
AEMP
ASUS Enhanced Memory Profile (AEMP) is an exclusive firmware feature for PMIC-restricted memory modules.
14(80A)+2(80A)+2(80A) Power Stages
The VRM features 14+ 2+ 2 power stages, each rated to handle 80 amps.
Alloy Chokes and Durable Capacitors
Hi-end chokes and durable capacitors are engineered to resist extreme temperatures, enabling performance that exceeds industry standards.
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.
Performance Cooling
- M.2 Backplate: An integrated backplate helps ensure that high-performance drives can deliver peak performance, even when airflow is restricted.
- M.2 Heatsinks: Heatsinks cover every slot to help keep onboard NVME SSDs at optimal temperatures for consistent performance and reliability.
- 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.
- 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.
- 4-Pin Fan Headers: The Strix B850-A features four chassis fan headers, each supporting auto-detection of PWM or DC fans.
Leading Connectivity
- 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.
- 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.
- 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.
- USB 20Gbps Port: A USB 20Gbps Type-C® port offers speedy data transfers up to USB 20Gbps.
Gaming Audio
- Dolby Atmos: ROG and Dolby® have partnered to bring superior gaming audio quality to users. Dolby Atmos expands on traditional surround sound systems by adding height channels, which enables immersive three-dimensional audio to be perceived from above, below, and around the listener.
- SupremeFX: ROG SupremeFX is a unique blend of hardware and software technologies that provide superior audio. The Strix B850-A implementation features the ALC4080 codec for high-resolution playback up to 32-bit/384 kHz across all channels. Front-panel output is streamed through the integrated Savitech amplifier that can drive high-fidelity acoustics to a wide variety of speakers and headsets.
Undeniably ROG Strix
The ROG Strix B850-A stands out with its striking white PCB, offering a fresh and modern aesthetic that seamlessly complements almost any system build. The matching metallic heatsinks enhance its clean, crisp look, while subtle RGB lighting on the I/O shroud allows you to either maintain a sleek, understated appearance or showcase a bold, luminous design.
Outshine the Competition
ROG Strix motherboards feature ASUS Aura technology, enabling full lighting control and a variety of presets for both onboard RGB LEDs and third-party accessories. Effects can be easily synced across compatible ROG graphics cards, monitors, keyboards, and mice to give your setup a unified look.
