• 1 x Q-Flash Plus button

Internal headers provide additional USB 3.2 Gen 1, USB 2.0, USB Type-C, RGB LED, addressable LED, TPM, and multiple fan connections, offering excellent flexibility for custom PC cases and lighting setups.

High Definition Audio and LAN
The integrated Realtek audio codec supports high definition 2, 4, 5.1, and 7.1 channel audio. With high end audio capacitors and noise guard design, it delivers clean sound for gaming headsets and speaker systems.

Networking is handled by a Realtek Gigabit LAN chip, ensuring reliable wired internet performance for online gaming, streaming, and large file transfers.

DIY Friendly Design
Building with the Gigabyte B550 Eagle is straightforward thanks to thoughtful design elements such as:

• PCIe EZ-Latch for easier graphics card removal
• Q-Flash Plus for BIOS updates without installing CPU, memory, or GPU
• Clearly labeled headers and accessible layout
• Solid pin UD power connectors for improved conductivity and durability

These details make it suitable for both first time PC builders and experienced enthusiasts.

Software and OS Compatibility
The motherboard supports Windows 11 64-bit and Windows 10 64-bit. It includes access to Gigabyte utilities such as BIOS management, system monitoring, RGB lighting control, and performance tuning tools through the APP Center.
