USB 3.0 support
The Gigabyte P55A-series motherboards support the latest generation SuperSpeed USB 3.0 technology made possible through an onboard NEC uPD720200 host controller. With superfast transfer rates of up to 5 Gbps, users are able to experience an almost a 10x improvement over USB 2.0. Additionally, backwards compatibility with USB 2.0 assures users of long term use of their legacy USB 2.0 devices. The onboard NEC SuperSpeed USB 3.0 technology also provides new power management features that include increased maximum bus power and device current draw to better accommodate power-hungry devices. -
SATA 6 Gbps support
Yet another onboard feature of Gigabyte P55A motherboards are Marvell's new SE9128 chips for high-speed SATA Revision 3.0 compatibility, delivering superfast 6Gbps link speeds for twice the data transfer rates of SATA Revision 2.0 (3 Gbps). When used in RAID 0 (Stripe) mode, Gigabyte P55A series motherboards offer even faster data transfer rates of up to 4x the speed of current SATA interfaces. -
3x USB power boost
Gigabyte P55A-series motherboards feature a 3x USB power boost, delivering greater compatibility and extra power for USB devices. Gigabyte's unique USB power design is also able to efficiently regulate output over the full voltage range, which greatly enhances USB device compatibility. In addition, dedicated lower resistance fuses ensure lower voltage drops, and provide more stable and plentiful power delivery. -
Industry's first 24 phase power vrm design
Gigabyte's 24 phase power VRM design utilizes the highest caliber components to provide unadulterated, smooth power delivery for the CPU. Like a high performance sports car engine, Gigabyte's 24 phase power design enables the best delivery of power to supercharge your system, giving extreme users unparalleled overclocking ability and the lowest temperatures to reach maximum performance levels. The innovative 24 phase power VRM has been designed and engineered to deliver fast transient response times through quick and seamless power delivery during extensive CPU loading variations. In addition, heat from the VRM is effectively reduced by spreading the load between the 24 power phases, resulting in a cooler and more stable platform. -
Ultra Durable 3
Gigabyte Ultra Durable 3 design, featuring 2 ounces of copper for both the Power and Ground layers which dramatically lowers system temperature by delivering a more efficient spreading of heat from critical areas of the motherboard such as the CPU power zone throughout the entire PCB. Gigabyte's Ultra Durable 3 also lowers the PCB impedance by 50%, which helps to reduce electrical waste and further lowers component temperatures. A 2oz Copper layer design also provides improved signal quality and lower EMI (Electromagnetic Interference), providing better system stability and allowing for greater margins for overclocking and more. -
Smart 6- a smarter way for PC system management
Gigabyte Smart 6 is designed with user-friendliness in mind, and offers a combination of 6 innovative software utilities that provide easier and smarter PC system management. Smart 6 allows you to speed up system performance, reduce boot-up time, manage a secure platform and recover previous system settings easily with a click of the mouse button. -
Dynamic Energy Saver 2
Gigabyte Dynamic Energy Saver 2 incorporates a host of intelligent features that use a proprietary hardware and software design to considerably enhance PC system energy efficiency, Reduce power consumption and deliver optimized auto-phase-switching for the CPU, Memory, Chipset, VGA, HDD, and fans with a simple click of button. -
XHD (eXtreme HardDrive)-Accelerating hard drive performance with ease
Accelerating system performance is made easy with the user friendly Gigabyte eXtreme Hard Drive (X.H.D). Gigabyte eXtreme Hard Drive (X.H.D) provides a quick and easy way to boost your hard drive performance simply by adding another hard drive. -
EuP Lot 6 support
The EuP (as known as Energy Using Products Directive) is part of new European Union's environment regulations. EuP established is based on the concern of environmental issues regards electronic devices been gained popularity and how to improve energy efficiency for better and greener life. Gigabyte presents standard motherboards to help you effectively improving system performance and saving more energy.
