Gigabyte GA-P55A-UD3 Motherboard

The Gigabyte P55A-series motherboards support the SuperSpeed USB 3.0 technology made possible through an onboard NEC uPD720200 host controller. With super-fast 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 power management features that include increased maximum bus power and device current draw to better accommodate power-hungry devices. 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.
