ASUS TUF GAMING B850M-PLUS WIFI AMD B850 Micro ATX Motherboard

The ASUS TUF GAMING B850M-PLUS WIFI delivers military-grade reliability and advanced performance for AMD Ryzen processors on the AM5 platform. This Micro ATX motherboard combines robust power delivery, extensive connectivity, and comprehensive cooling to handle demanding gaming workloads and AI PC applications.

Military-Grade Power Delivery

Engineered with a 14+2+1 phase power design featuring 80A DrMOS power stages, this motherboard ensures stable power delivery for high-core-count AMD processors. The eight-layer PCB design efficiently dissipates heat around voltage regulators, while ProCool power connectors maintain full contact with PSU cables to prevent hotspots. TUF components including durable chokes and 5K black metallic capacitors provide 52% wider temperature tolerance and 2.5X longer lifespan than standard capacitors.

DDR5 Memory and PCIe 5.0 Performance

Four DDR5 DIMM slots support up to 256GB of memory with speeds reaching 8000+MT/s through overclocking. AMD EXPO support and ASUS AEMP technology automatically optimize memory profiles for maximum performance. The primary PCIe 5.0 x16 slot delivers twice the bandwidth of PCIe 4.0 for next-generation graphics cards, while three M.2 slots (including one PCIe 5.0 M.2) provide flexible high-speed storage options with dedicated heatsinks.

Advanced Cooling System

Enlarged VRM heatsinks cover MOSFETs and chokes for improved thermal management. All three M.2 slots feature dedicated heatsinks to maintain optimal SSD temperatures. Multiple fan headers support both PWM and DC fans with intelligent control through Fan Xpert 4, allowing temperature mapping from CPU, motherboard sensors, and compatible ASUS graphics cards.

Connectivity and Expansion

Wi-Fi 6E provides tri-band wireless connectivity across 2.4/5/6GHz frequencies with Bluetooth 5.3 support. Realtek 2.5Gb Ethernet with TUF LANGuard protection delivers enhanced network performance. USB connectivity includes rear USB 20Gbps Type-C, multiple USB 10Gbps ports, and front USB 10Gbps Type-C support. DisplayPort and HDMI outputs enable integrated graphics functionality.

DIY-Friendly Features

PCIe Slot Q-Release enables tool-free graphics card removal with a single lever. M.2 Q-Latch eliminates screws for SSD installation. Q-Antenna allows snap-in WiFi antenna attachment. BIOS FlashBack supports firmware updates without CPU or memory installed. Q-LED diagnostic lights provide instant troubleshooting during startup.

Enhanced Protection

SafeSlot reinforced PCIe slots and SafeDIMM memory sheaths ensure secure component installation. ESD Guards provide up to +/-10kV air discharge protection. The corrosion-resistant stainless steel rear I/O panel passes rigorous 72-hour salt fog testing for extended durability.

Premium Audio and RGB

Realtek ALC1220P codec delivers 7.1 surround sound with 120dB SNR for line out. DTS Audio Processing enhances gaming audio with reduced distortion and deeper bass. Aura Sync RGB lighting synchronizes with compatible ASUS components and peripherals through addressable Gen2 RGB headers.
