To ensure maximum Turbo Boost and overclocking performance of AMD's new generation CPU, GIGABYTE UD series motherboard equip the best VRM design ever built with the highest quality components.
GIGABYTE B650 Motherboards are ready to work with the PCIe 4.0 devices which are expected to experience twice bandwidth than the current PCIe 3.0 devices. To reach the high speed and maintain good signal integrity, GIGABYTE R&D uses the low impedance PCB to provide the maximum performance.
AORUS is offering a tested and proven platform that the memory overclocking capability is able up to 8000 and beyond. All users need to do for achieving this extreme memory performance boost is to ensure that their DDR5 memory modules are AMD EXPO™/ Intel® XMP capable, the EXPO/XMP function is activated and enabled on their AORUS motherboard.
Smart Fan 6 contains several unique cooling features that ensure gaming PC maintain its performance while staying cool and quiet. Multiple fan headers can support PWM/DC fan and pump, and users can easily define each fan curve based on different temperature sensors across the board via intuitive user interface.
We increase control points from 5 to 7 and larger fan speed graph for precise and easier fan curve control.
Fan curve can be quickly switch with Slope and Stair modes for different user scenario. Slope is traditional and intuitive linear fan speed curve. With newly added Stair non-linear mode, fan keeps at same speed between specified temperature interval.
For advanced users, we provide fan speed manual input for more precise control.
Use can place 4 EZ Tuning points at rough temperature/fan speed, and Smart Fan 6 can quickly generate a fan curve.
Fan curve profile can be saved in BIOS ROM, profile will be kept after updating BIOS

GIGABYTE Motherboards' unparalleled performance is guaranteed by innovative and optimized thermal design to ensure the best CPU, Chipset, SSD stability and low temperatures under full load application and gaming performance.

GIGABYTE Motherboards enable the ultimate connection experience with blazing data-transfer speeds through the next generation network, storage.

GIGABYTE motherboards bundle several useful and intuitive software to help users to control every aspect of motherboard and provide customizable lighting effect with outstanding aesthetics to fit your unique personality.
The USB Type-C with front USB 3.2 Gen 1 and rear USB 3.2 Gen 2 ports provide with speeds up to 5Gbps & 10Gbps . With doubled bandwidth compared to the previous generation as well as backward compatibility with USB 2.0, the improved USB protocol is available now over the new reversible USB Type-C™ and the traditional USB Type-A connector for better compatibility over a wider range of devices
AORUS motherboards use high-end audio capacitors. These high quality capacitors help deliver high resolution and high fidelity audio to provide the most realistic sound effects for gamers.
AORUS motherboards feature an audio noise guard that essentially separates the board’s sensitive analog audio components from potential noise pollution at the PCB level.
Twin Digital VRM design leverages 8 VCORE phases to ensure electrical throughput that can handle AMD's Ryzen 7000 Series processors as well as various overclocking parameters. EXPO and XMP overclocking boosts RAM up to 6400 MHz for enhanced multitasking and rendering performance.
The EASY MODE shows important hardware information in one page including CPU clock, Memory, Storage, Fan.
Add constantly used items into the favorite menu for quick access.
Show all kinds of storage information including SATA, PCIE and M.2 interface.
List all changes before saving and exiting bios. Quickly review overall settings modification.
Clearly show each loadline calibration setting in an intuitive curve graph.

A multi-function reset pin headers that can be reconfigured to other function in BIOS for different user scenarios.
Unlock the latch of the PCIe slot easily when remove the graphics card in the PCIe slot.
With GIGABYTE Q-Flash Plus, you don't need to install the CPU, memory and graphics card nor enter the BIOS menu to flash the BIOS. Just download and save a new BIOS file (rename to gigabyte.bin) on the USB flash drive, then press the dedicated Q-Flash Plus button and you’re good to go!
Designed to maintain thermal performance and prevent system throttling, the B650M K's advanced thermal heat sinks, VRM heat sink, M.2 Thermal Guard, and 6-layer 2x copper PCB work together to ensure that onboard components are safe under heavy loads. Smart Fan 6 application gives users the ability to monitor and operate connected fans to assist with cooling capabilities.
The back panel of the B650M K includes four USB-A 2.0 ports for low-powered devices such as mice, keyboards, and controllers. You also get two USB-A 3.2 Gen 1 and one USB-A 3.2 Gen 2 port, giving you up to 5 and 10 Gb/s data transfer speeds, respectfully, allowing you to connect external drives, audio interfaces, and more with ease. You also get two USB-C 3.2 Gen 2 ports with one located on the back panel and the other for the front panel, both covering a wide range of device utility complete with 10 Gb/s data transfer speeds.
With an array of RGB headers, you can use GIGABYTE's RGB Fusion and Control Center software to customize your rig with a wide range of colors and lighting effects, turning your rig into the centerpiece of your gaming room. UEFI BIOS settings can be easily accessed and allow you to fine-tune your performance profile according to your needs. A multi-key function reset button can be reconfigured to other functions within the BIOS to meet different user scenarios such as acting as an RGB switch, boot directly to BIOS, and enable Safe Mode.
Sporting an easy DIY design, the B650M K provides you with several enhancements that make the installation of components a breeze. PCIe EZ-Latch provides quick access to your M.2 storage drives and Q-Flash Plus enables you to update the BIOS settings with only a few power cables, RAM, and processor.
