4 3 Phases Pure Digital VRM Solution with Low RDS(on) MOSFETs GIGABYTE UD series motherboards use a 4 3 phases pure digital PWM Low RDS(on) MOSFETs design to support the 3rd Gen AMD Ryzen CPUs by offering incredible precision in delivering power to the motherboards most power-hungry and energy-sensitive components as well as delivering enhanced system performance and ultimate hardware scalability. NVMe PCIe Gen3 x4 M.2 Connector GIGABYTE Motherboards are focused on delivering M.2 technology to enthusiasts who want to maximize their systems potential. Exclusive Realtek 8118 Gaming LAN High Speed Gigabit LAN with Automatic Bandwidth Allocation Realtek 8118 LAN is a high performance and friendly network chip for gaming players with automatic bandwidth allocation to ensure the highest network priority of the game or application. It can provide users the most comprehensive features and the fastest and smoothest Internet experience. HDMI 2.1 for 4K / 60P / 21:9 / HDCP 2.3 Support HDMI 2.1, which is backwards compatible with HDMI 2.0/ 1.4 and offering 48 Gb/s of bandwidth  twice times more than previous generation. This unlocks the potential for users to transfer multiple video streams, as well as a native cinematic 21:9 ratio (which most movies are shot in), Full HDR and HDCP 2.3 support, to offer the best visual experience for viewers. Note: Only New Gen AMD Ryzen with Radeon Graphics processors support displaying function. The Industrys Leading LAN Static-Electricity & Surge Protection GIGABYTE motherboards use ICs with up to 3 times the ESD resistance levels compared to traditional ICs. This helps to better protect the motherboard and its components against potential damage caused by static electricity. GIGABYTE motherboards also feature special anti-surge ICs that protect your motherboard, and your PC from any surge in power delivery that may occur, helping to ensure that your PC is equipped to deal with any potentially irregular and inconsistent power delivery. High-End Audio Capacitors GIGABYTE 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. Audio Noise Guard GIGABYTE motherboards feature an audio noise guard that essentially separates the boards sensitive analog audio components from potential noise pollution at the PCB level. Smart Fan 5 With 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. Different models have different number of fan pin headers and temperature sensors. Smart Fan 5 function may vary by model. Fan Stop Achieve fan silence. With Fan Stop, map any fan to stop completely when temperatures drop below a specified threshold. Which fan stops, based on readings from which sensor, and at what temperatureall of it can be customized to your liking. Hybrid Fan Pin Headers Assume complete control over your liquid cooling setup! Smart Fan 5 receives up-to-the-second information on flow-rate and water-temperature through the Hybrid Fan Pin Headers or external thermistor sensors giving you absolute mastery over your PC. All Hybrid Fan Headers can automatically detect the type of cooling device whether it be fan or pump with different PWM or Voltage modRGB FUSION 2.0 With A520 Motherboards, RGB Fusion 2.0 is even better with Addressable LEDs. RGB Fusion 2.0 offers users the option to control onboard RGB and external RGB / Addressable LED light strips* for their PC build. Already feature filled with colors and patterns, RGB Fusion 2.0 are now upgraded to improve the Addressable LED support. With external Addressable LED strips, where each LED is digitally addressable that users can experience even more patterns, styles, and illuminations. With A520 Motherboards support the external 5V Addressable LED lighting strips and up to 300 LED lights. RGB Fusion 2.0 with Addressable LEDs comes with new patterns and various speed settings with more to come. * The external RGB LED strips and Addressable LED strips are not included with Motherboard purchase. Q-Flash Plus Update the BIOS easily without installing the CPU, memory and graphics card. With GIGABYTE Q-Flash Plus, you dont 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 youre good to go! Solid Pin Power Connectors A520 motherboards feature solid plated ATX 12V 8pin power connectors for offering stable power supply while CPU overloading. Solid Pin Power connector advantages Larger contact area for electricity More metal quantity to sustain higher power and generated heat Ultra durable and longer lifespanSTART SULFURIZATION PROTECTION Sulfur compounds in the air can penetrate tiny onboard resistors creating chemical change and causing these resistors to open or short. If either of these occurs the motherboard will fail to function. By equipping resistors with an Anti-Sulfur Design GIGABYTE gives Ultra Durable Motherboards a whole new meaning.
