The GIGABYTE B860 DS3H WIFI6E (Part Number: 9MB86D3H6-00-G13 / Model: B860 DS3H WIFI6E) brings GIGABYTE's legendary Ultra Durable™ engineering to the Intel B860 LGA 1851 platform. Designed for gamers, content creators, and workstation builders who want full-size ATX expandability without paying a Z890 chipset tax, it combines PCIe 5.0 graphics and storage bandwidth with effortless DIY assembly features.
Expanded Key Features
8+1+2+2 Hybrid Digital VRM & RL-ILM Socket: Delivers clean, stable power to Intel Core Ultra Series 2 processors using 50A P-PAK power stages and a solid-pin 8-pin CPU power connector. The Reduced Load Independent Loading Mechanism (RL-ILM) prevents CPU heatspreader bending and lowers temperatures by up to 4°C.
D5 Bionic Corsa DDR5 Performance (Up to 9066 MT/s): Equipped with 4× DDR5 DIMM slots supporting up to 256GB (64GB per DIMM) in dual-channel architecture. Powered by AORUS AI Snatch and HyperTune BIOS, it unlocks Intel XMP memory speeds up to 9066 MT/s (O.C.).
PCIe 5.0 x16 Graphics & Dual M.2 Thermal Guard Storage: Features 1× PCIe 5.0 x16 UD Slot (reinforced for heavy GPUs), 4× PCIe 4.0 x1 slots for capture or expansion cards, and 2× M.2 slots (1× PCIe 5.0 x4 + 1× PCIe 4.0 x4, up to Type 25110) outfitted with M.2 Thermal Guard heatsinks to prevent SSD thermal throttling.
Wi-Fi 6E (6GHz) & Realtek 2.5GbE LAN: Enjoy low-latency online gaming and rapid file transfers with 802.11ax Wi-Fi 6E across the 2.4/5/6 GHz bands, Bluetooth 5.3, and a Realtek 2.5 Gigabit Ethernet port.
DIY-Friendly EZ-Latch & WIFI EZ-Plug: Assemble and upgrade in seconds. WIFI EZ-Plug combines both Wi-Fi antenna leads into a single one-click plug, while PCIe EZ-Latch and M.2 EZ-Latch Plus provide screwless, quick-release installation for your GPU and NVMe drives.
20Gbps USB-C & Dual 4K Display Outputs: The rear I/O panel includes a high-speed USB 3.2 Gen 2x2 Type-C (20Gbps) port, HDMI 2.1 (4096×2160@60Hz), DisplayPort 2.1 (3840×2160@144Hz), and an internal EZ Debug Zone with Q-Flash Plus for updating the BIOS without a CPU or RAM installed.
Why This Product Stands Out
While competing entry-level B860 boards often restrict builders to cramped Micro-ATX layouts or downgrade the primary graphics and M.2 slots to PCIe 4.0, the GIGABYTE B860 DS3H WIFI6E gives you a full-size ATX footprint with both PCIe 5.0 x16 graphics and PCIe 5.0 M.2 storage, plus WIFI EZ-Plug and 9066 MT/s DDR5 support.
