Product features
Dual NVMe PCIe 4.0/3.0 M.2 connectors
With NVMe PCIe 4.0/3.0 x4 and PCIe 3.0 x2 M.2 connectors onboard, GIGABYTE Motherboards bring users to experience NVMe mode or SATA mode connectivity for M.2 SSD devices. Delivering up to 64 Gb/s data transfer speed, the dual M.2 connectors design provides an ideal storage solution while also supporting in RAID modes.GbE LAN with bandwidth management
GbE LAN features a network bandwidth management application which helps to improve network latency and maintain low ping times to deliver better responsiveness in crowded LAN environments.LAN static-electricity and 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.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.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.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 board's sensitive analog audio components from potential noise pollution at the PCB level.Solid pin power connectors
B550 motherboards feature solid plated ATX 12V 8pin power connectors for offering stable power supply while CPU overloading.Surge protection
GIGABYTE motherboards also feature special anti-surge IC that protect your motherboard, helping to ensure that your PC is equipped to deal with any potentially irregular electrical spikes.Humidity protection GLASS FABRIC PCB
There is nothing more harmful to the longevity of your PC than moisture, and most parts of the world experience moisture in the air as humidity at some point during the year. GIGABYTE motherboards have been designed to make sure that humidity is never an issue, incorporating a Glass Fabric PCB technology that repels moisture caused by humid and damp conditions. Glass Fabric PCB technology uses a PCB material which reduces the amount of space between the fiber weave, making it much more difficult for moisture to penetrate compared to traditional motherboard PCBs. This offers much better protection from short circuit and system malfunction caused by humid and damp conditions.High temperature protection Lower RDS (on) MOSFETs design
GIGABYTE motherboards use Low RDS (on) MOSFETs which reduce energy wastage through unnecessary residual heat dissipation. This all amounts to tangible energy savings which are beneficial for both end-users and the environment without impacting system performance.Refreshed BIOS
The BIOS is essential for users during initial setup to allow for the most optimal settings. With a GUI and easier to use functionalities, GIGABYTE has been able to reinvent the BIOS to give users a better experience while setting up their system.Key selling points
