Gigabyte B840 Motherboard - WiFi 6E, Socket AM5, ATX

Gigabyte B840 Motherboard - WiFi 6E, Socket AM5, ATX arrives as a versatile ATX platform for AMD Ryzen desktop builds, offering modern connectivity and broad CPU support for enthusiasts and productivity users alike.

This motherboard is built around the AMD B840 chipset and supports Socket AM5 processors from the AMD Ryzen 7000, 8000 and 9000 series, making it suitable for current and next-generation Ryzen CPUs. The board uses a UEFI AMI BIOS (256 Mbit) and includes clear CMOS button and jumper options for easy recovery and tuning.

Memory support is cutting-edge with four DIMM slots for DDR5-SDRAM in dual-channel configuration, accommodating up to 256 GB (up to 64 GB per slot) and speeds up to 8200 MHz (supported profiles listed). Memory is unbuffered and non-ECC, ideal for high-performance gaming and content creation systems.

Storage options are plentiful with three M.2 slots (two supporting PCIe 4.0 and one PCIe 3.0) and four SATA III connectors, enabling up to seven drives (HDD & SSD) and RAID 0/1/5/10 support for performance or redundancy. Expansion space includes three PCIe x16 (Gen3) slots plus one PCIe x16 (Gen4) slot for flexible GPU and add-on card configurations.

Connectivity and audio are well covered: HDMI 2.1 and DisplayPort 1.4 outputs support up to 4096 x 2160 resolution with HDCP 2.3, a Realtek RTL8125 2.5 Gigabit Ethernet port provides fast wired networking, and onboard Wi-Fi 6E (Realtek RTL8852CE) with Bluetooth 5.3 offers modern wireless speed and range. USB connectivity includes multiple USB 2.0, USB 3.2 Gen1 and Gen2 Type-A and Type-C ports for peripherals and fast data transfer.

Cooling and system management features include passive cooling, multiple fan headers (two CPU fans, four chassis fans), two water-pump connectors, and PC health monitoring for fan, temperature, voltage and water cooling. The board also supports TPM and includes RGB LED headers (four) for personalized lighting.

Typical use cases include a high-performance gaming rig using a Ryzen 7000/8000/9000 CPU and a PCIe 4.0 SSDs setup, a content-creation workstation requiring lots of fast RAM and multiple storage devices, or an all-purpose home/office PC that benefits from Wi‑Fi 6E and 2.5 GbE networking. The Gigabyte B840 ATX motherboard is a reliable, future-ready foundation with a three-year warranty and bundled essentials such as antenna, screws and a CR2032 battery to get a build started quickly.
