The GIGABYTE B850 AORUS STEALTH is a high-performance ATX motherboard designed for gamers, enthusiasts, and creators who want to fully leverage the power of the latest AMD AM5 platform. Built on the AMD B850 chipset, it supports AMD Ryzen™ 9000, 8000, and 7000 Series processors, delivering excellent performance, next-generation connectivity, and strong future-proofing for modern PC builds.
Performance & Compatibility
Equipped with the AM5 socket and AMD B850 chipset, the B850 AORUS STEALTH provides broad CPU compatibility and optimized performance for gaming, content creation, and multitasking workloads. It supports dual-channel DDR5 memory with speeds up to DDR5-8200 (OC) and a maximum capacity of 256 GB across four DIMM slots. Support for AMD EXPO™ and XMP memory profiles allows users to easily achieve high memory performance and stability.
Graphics & Display Output
The motherboard supports integrated AMD Radeon™ Graphics when paired with compatible Ryzen processors. A rear HDMI 2.1 port enables display output of up to 4096 × 2160 at 60 Hz, with support for HDR and HDCP, making it suitable for high-resolution monitors and multimedia setups without the need for a discrete graphics card.
Storage & Expansion
For high-speed storage and expandability, the B850 AORUS STEALTH features four M.2 slots and two SATA 6 Gb/s ports, allowing flexible storage configurations. CPU-connected M.2 slots support PCIe Gen5 SSDs with Ryzen 9000 and 7000 Series processors, while chipset-connected M.2 slots provide PCIe Gen4 bandwidth. Comprehensive RAID support includes RAID 0, 1, 5, and 10 for NVMe SSDs (RAID 5 available on Ryzen 9000 Series CPUs), as well as RAID 0 and 1 for SATA devices, offering both performance and data redundancy options.
Networking & Wireless Connectivity
The motherboard is equipped with a Realtek 5GbE LAN controller, providing ultra-fast and stable wired networking. It also integrates a Realtek Wi-Fi 7 wireless module, supporting 2.4 GHz, 5 GHz, and 6 GHz bands with advanced throughput and reduced latency for online gaming, streaming, and high-speed downloads. Bluetooth® 5.4 support ensures seamless connectivity with wireless peripherals and accessories.
Audio & I/O
High-quality audio is powered by the Realtek® ALC1220 codec, delivering immersive multi-channel sound with support for 2/4/5.1/7.1-channel audio, DSD playback via the rear line-out, and optical S/PDIF output. The rear I/O panel offers a wide range of USB connectivity, including USB-C®, USB 3.2 Gen 2, USB 3.2 Gen 1, and USB 2.0 ports, ensuring compatibility with modern peripherals and high-speed external storage devices.
Builder-Friendly Design & Features
Designed with system builders in mind, the B850 AORUS STEALTH includes Q-Flash and Q-Flash Plus for easy BIOS updates, even without a CPU or memory installed. Support for GIGABYTE Control Center (GCC) allows centralized control of system monitoring, fan tuning, and performance optimization. Advanced hardware monitoring, multiple fan and pump headers, and robust thermal design help maintain stable operation under heavy workloads. The stealth-focused layout and clean connector placement also contribute to a tidy, modern system build.
Ideal Choice for Modern AM5 Builds
With its combination of PCIe 5.0 readiness, high-speed DDR5 support, Wi-Fi 7 connectivity, and extensive storage options, the GIGABYTE B850 AORUS STEALTH is an excellent foundation for high-performance AMD systems that demand reliability, expandability, and next-generation features.
