The Power eSATA solution combines the eSATA connector and power source together, allowing you to use external SATA devices without the need of additional power source.
|Dual Intelligent Processors 2 with DIGI+ VRM
Digital Power Design: The New Standard. The world’s first Dual Intelligent Processors from ASUS pioneered the use of two onboard chips - EPU (Energy Processing Unit) and TPU (TurboV Processing Unit). The new generation of Dual Intelligent Processors 2 with DIGI+ VRM provides precise Vcore PWM, integrated graphics voltages and frequency module adjustments with minimal power loss through BIOS tuning and an exclusive user interface to increase the board’s overclocking range while performance reaches its full potential. ASUS DIGI+ VRM digital power design empowers users with superior flexibility and perfect precision to ensure optimized performance, extreme system stability and greater power efficiency.
The Ultimate Turbo Processor. Unleash your performance with ASUS' simple onboard switch or AI Suite II utility. The TPU chip offers precise voltage control and advanced monitoring through Auto Tuning and TurboV functions. Auto Tuning offers a user friendly way to automatically optimize the system for fast, yet stable clock speeds, while TurboV enables unlimited freedom to adjust CPU frequencies and ratios for optimized performance in diverse situations
Energy Efficiency All Around. Tap into the world's first real-time PC power saving chip through a simple onboard switch or AI Suite II utility. Get total system-wide energy optimization by automatically detecting current PC loadings and intelligently moderating power consumption. This also reduces fan noise and extends component longevity!
Auto System Level Up. Achieve extreme yet stable overclocking results automatically with Auto Tuning! With built-in stability testing, Auto Tuning allows beginners to easily upgrade their CPU performance at no extra cost.
Herald the Arrival of a New Digital Power Design Era. VRM, or voltage regulator modules, are considered among the most essential motherboard design components. They supply the voltage demanded by the CPU, and a good VRM must intelligently detect actual CPU power draw to provide precise power accordingly. ASUS DIGI+ VRM features a digital programmable microprocessor onboard to perfectly match digital power signal (SVID) requests from the CPU, eliminating digital-to-analog conversion lag. The precise power delivery minimizes power transfer loss to provide highest power efficiency, greater performance, and rock solid stability with the most flexible power adjustment than traditional analog power design.
Active Quiet & Cool. ASUS Fan Xpert intelligently allows users to adjust both the CPU and chassis fan speed according to different ambient temperature, which is caused by different climate conditions in different geographic regions and system loading. Built-in variety of useful profiles offer flexible controls of fan speed to achieve a quiet and cool environment.
|AI Suite II
One-stop Access to Innovative ASUS Features. With its user-friendly interface, ASUS AI Suite II consolidates all exclusive ASUS features into one simple-to-use package. It allows users to supervise overclocking, energy management, fan speed, voltage, and sensor readings. This all-in-one software offers diverse and easy to use functions, with no need to switch back and forth between different utilities.
|UEFI BIOS (EZ Mode)
Flexible & Easy BIOS Interface. Exclusive to ASUS motherboards, its UEFI (Unified Extensible Firmware Interface) is the first ever mouse-controlled graphical BIOS interface designed with dual selectable modes. It delivers a user-friendly interface that goes beyond traditional keyboard-only BIOS controls to enable more flexible and convenient input with quick scrolling. Users can easily navigate the UEFI BIOS with the smoothness of their operating system. Quick and simple overclocking and setup sharing is facilitated by the F12 hotkey BIOS snapshot feature. The exclusive EZ Mode displays frequently-accessed setup info, while the Advanced Mode is for experienced performance enthusiasts that demand far more intricate system control, including detailed DRAM information.
DIY quickly, DIY easily! ASUS Q-Design enhances your DIY experience. All of Q-LED, Q-Slot and Q-DIMM design speed up and simplify the DIY process!
The motherboard is European Union´s Energy-related Products (ErP) ready, and ErP requires products to meet certain energy efficiency requirements in regards to energy consumptions. This is in line with ASUS vision of creating environment-friendly and energy-efficient products through product design and innovation to reduce carbon footprint of the product and thus mitigate environmental impacts.
