Fremont, CA, Sept. 8th, 2009 – ASUS, the leading innovator of advanced motherboard solutions, today launches the ASUS P7P55D Series motherboards. Featuring the Intel P55 Express chipset, the P7P55D Series supports the latest LGA 1156 socket for Intel Core i7/Core i5 Processors for maximum performance. The P7P55 Series is based on groundbreaking “Xtreme Design”, a winning design formula drawn from many years of engineering innovation, to optimize overall system performance and hardware reliability. It also includes the latest Hybrid Technology – Hybrid Processor, Hybrid Phase, and Hybrid OS – to give users intelligent performance enhancements, active cooling, and rapid online access.

Achieving 6Gbps Storage Bandwidth with Exclusive Expansion Bridges
Equipped with a specially-designed onboard chip, the P7P55D Premium is the first motherboard to natively support 6Gbps data transfer bandwidth with the latest SATA storage interface. The P7P55D Premium’s expansion bridge nearly doubles the throughput on the latest SATA devices, – enabling 50% faster reading and writing of disk data. For other P7P55D Series models, ASUS also provides an expansion card to achieve the same results.

Optimizing Efficiency with Revolutionary Hybrid Phase Power Delivery
Users can expect maximum power efficiency, extremely cool operation, and enhanced component longevity from the P7P55D Series. With its Hybrid Phase Technology – combining ASUS Xtreme Phase with ASUS T.Probe – the series delivers maximum efficiency and extremely stable power. ASUS T.Probe is the world’s first active cooling technology that detects and balances power phase loadings and temperatures in real time. A new frequency conversion technology further improves efficiency by maximizing energy utility. High-grade materials enhance component longevity and further minimize power loss.

Enhancing Performance with an Intelligent Hybrid Processor
The P7P55D Series lets users achieve superior overclocking performance with the latest Intel CPU and the ASUS Hybird Processor: TurboV EVO. Both novice and advanced overclockers can easily boost system performance with TurboV EVO’s intuitive interface and three easy-to-use tools. Auto Tuning automatically overclocks and self-tests the system to an extreme yet stable state. ASUS OC Profile offers the best overclocking settings for different scenarios. ASUS Turbo Key assigns keyboard hotkeys for instantaneous overclocking. ASUS TurboV Remote* allows users to adjust performance settings from a convenient controller.

Hybrid OS Delivers Express Gate and Windows 7 Benefits
Hybrid OS integrates Windows readiness and ASUS Express Gate onto the ASUS P7P55D Series for more flexibility. Users can upgrade to Windows 7 and have better security and faster performance, while Express Gate delivers rapid access to common online applications – within five seconds.

Warranty and Service
ASUS offers a no-strings attached 3 year warranty on all P7P55D Series models. Additionally, many models qualify for ASUS Premium Service, offering cross-ship replacement for minimal downtime. For more information about APS, visit:
