Gigabyte B850 AORUS STEALTH ICE AM5 ATX Motherboard Wi-Fi 7
The Gigabyte B850 AORUS STEALTH ICE AM5 ATX Motherboard Wi-Fi 7 is built for users who demand fast storage, reliable power delivery, and modern connectivity on the AM5 platform. It pairs PCIe 5.0 M.2 slots with Wi-Fi 7 and 5GbE networking, designed for content creators, gamers, and enthusiasts who need both speed and stability.
Why this product
Four M.2 slots including PCIe 5.0
Two slots run at full PCIe 5.0 x4 speed for the fastest NVMe drives, with two additional PCIe 4.0 x4/x2 slots for flexibility. All four slots ship with thermal guards to manage heat during sustained transfers.
Wi-Fi 7 and 5GbE networking
Dual connectivity options with Realtek Wi-Fi 7 (supporting 2.4/5/6 GHz) and a dedicated 5GbE LAN port. The Wi-Fi antenna is tuned for directional gain.
7+7 phase power design
Parallel power stages deliver stable voltage to the CPU under load, essential for multi-core workloads and overclocking. Combined with thermal armor around the VRM, this keeps power delivery cool even during sustained use.
PCIe 5.0 x16 slot with UD protection
The primary graphics slot is rated for 10× mechanical strength and features enhanced heat dissipation. Supports the latest high-end graphics cards without compromise.
GIGABYTE User-Centred BIOS
Quick Access function pulls nine essential settings into Easy Mode, cutting navigation time for common tweaks. Q-Flash Plus allows BIOS updates without a CPU installed.

- DDR5 memory from 4800 MT/s up to 8200 MT/s (overclocked), with support for up to 256 GB across four DIMM slots.
- NVMe SSDs in M.2 2280 and 22110 form factors, SATA 6 Gb/s drives, and external USB storage via 11 total USB ports (3 USB-C, 8 USB-A).
- ATX-sized cases with standard power connections (24-pin ATX and 4+8 pin CPU headers with UD Solid Pin connectors).
- RAID is supported for NVMe SSDs (RAID 0, 1, 5, 10) and SATA drives (RAID 0, 1 only); RAID does not apply to single drives.
Best for
- Multi-core workloads and content creation. The 7+7 phase VRM and thermal armor handle sustained CPU power draw without throttling.
- Fast storage builds. PCIe 5.0 x4 M.2 slots and RAID support for NVMe SSDs enable both speed and redundancy.
- Enthusiasts and overclockers. Robust power delivery, debug LEDs, and BIOS Quick Access reduce trial-and-error tuning time.
- Wireless-first networking. Wi-Fi 7 with directional antenna and 5GbE wired option provide modern connectivity without compromise.
- RGB-heavy builds. Four LED headers (one RGB, three ARGB GEN2) let you sync lighting across the motherboard and peripherals via GCC.
Trade-offs
- Budget builds. This is a high-end AM5 board designed for performance; entry-level B850 options exist at lower cost.
- Very large memory setups beyond 256 GB. Only four DDR5 DIMM slots are available.
- Compact or ITX cases. The ATX form factor requires a full-size chassis.
- Users who do not need Wi-Fi. The Wi-Fi 7 module is built-in and cannot be removed, and no Wi-Fi-free SKU is offered.
