Power Delivery that\'s Precise and Efficient

4+3 PURE DIGITAL VRM WITH LOW RDS(ON) MOSFETSGIGABYTE motherboards utilize a 4+3 phases pure digital PWM + Low RDS(on) MOSFETs design to support 3rd Gen AMD Ryzen™ CPUs. It offers impeccable precision when delivering power to the motherboard\'s most demanding and energy-sensitive components, as well as delivering enhanced system performance and ultimate hardware scalability.

PCIe 4.0* Hardware Design

Enhance your Transfer Speeds

NVME PCIE 4.0*/3.0 M.2 CONNECTORWith an NVMe PCIe 4.0*/3.0 x4 M.2 connector onboard, you can utilise NVMe mode or SATA mode connectivity for M.2 SSD devices. They deliver up to 64 Gb/s data transfer speeds. The M.2 connector design provides an ideal storage solution for fast and efficient gaming.

Versatile Connectivity Options

I/O PORTS?|? REALTEK 8118 GAMING LAN?|?REAL-TIME NETWORK MONITORINGWith integrated I/O ports, building a GIGABYTE PC is even easier. Realtek 8118 LAN is an impressive network chip for gamers with automatic bandwidth allocation to ensure the highest network priority of the game or application. It can deliver the most comprehensive features and the fastest and smoothest Internet experience.

Stay Protected from Surges in Power

LAN STATIC-ELECTRICITY & SURGE PROTECTIONGIGABYTE motherboards use ICs with up to three times the ESD resistance levels compared to traditional ICs. This protects the motherboard and its components a lot better against damage caused by static electricity. GIGABYTE motherboards also feature special anti-surge ICs that protect your motherboard and PC from any surges in power, making sure that your PC is equipped to deal with any potentially irregular or inconsistent power delivery.

Full Support for Video Streams

HDMI 2.1 FOR 4K / 60P / 21:9 / HDCP 2.3 SUPPORT

HDMI SUPPORTHDMI 2.1, which is backwards compatible with HDMI 2.0/1.4 and offers twice more bandwidth than previous generations. This unlocks the potential for you to transfer multiple video streams, as well as a native cinematic 21:9 ratio, Full HDR and HDCP 2.3 support, to offer the best visual experience.

INCREDIBLE SPEEDHDMI 2.1 supports up to an impressive 48Gb/s bandwidth. Note: Only New Gen AMD Ryzen™ with Radeon™ Graphics processors support displaying function.

Stay Cool under Demanding Loads

SMART FAN 5With Smart Fan 5 users can ensure that their gaming PC can maintain its performance while staying cool. Smart Fan 5 allows users to interchange their fan headers to reflect different thermal sensors at different locations on the motherboard. Not only that, with Smart Fan 5 more hybrid fan headers that support both PWM and Voltage mode fans have been introduced to make the motherboard more liquid cooling friendly. Achieve fan silence. With Fan Stop, map any fan to stop completely when temperatures drop below a specified threshold. Which fan stops is based on readings from which sensor, and what temperature of the stopping threshold can be customized to your liking. With Smart Fan 5 choose from different modes, Quiet to Full Speed, to match your system usage preferences. For each fan or pump, you can use the intuitive fan curve to define trigger thresholds and corresponding fan speeds.

Illuminate your PC with RGB Fusion 2.0

RGB FUSION 2.0With this GIGABYTE motherboard, RGB Fusion 2.0 is even better. It offers addressable LEDs and lets you control onboard RGB and external RGB / addressable LED light strips for your PC. Filled with various colours and modes, RGB Fusion 2.0 on GIGABYTE motherboards are now upgraded with addressable LED support. With LED strips, you can experience more patterns, styles, and illuminations. Utilise support for either 5v or 12v addressable LED strips and up to 300 LED lights.

Enter the Gaming World with Incredible Audio

HIGH-END AUDIO CAPACITORSGIGABYTE motherboards use high-end audio capacitors. These high quality capacitors help deliver high resolution and high fidelity audio and offer the most realistic sound effects for gamers.

AUDIO NOISE GUARDThe audio noise guard essentially separates the board\'s sensitive analog audio components from the potential noise pollution at the PCB level.

Get Up and Running in Seconds

Q-FLASH PLUSWith 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!

STEP 1Plug the 24pin & 8pin power supply cable into the motherboard.

STEP 2Download and unzip the motherboard\'s compressed BIOS file and rename to \"gigabyte.bin\", save to a USB flash-drive, and plug it into the Q-Flash USB port.

STEP 3Press the Q-Flash button, and the motherboard will start updating the BIOS automatically.
