ASUS P5N64 WS Professional with EPU Provides High Performance with Exceptional Power Savings

Taipei, Taiwan, May 13, 2008 - Catering to users who require a workstation motherboard with advanced data transfer solutions, superb performance and still provide huge energy savings, ASUS, worldwide leader in motherboard design, has today released the powerful ASUS P5N64 WS Professional motherboard. Joining the growing ranks of ASUS EPU-equipped motherboards, the ASUS P5N64 WS Professional helps users save energy by utilizing a combination of the ASUS EPU and HE 95 technologies. This top-notch piece of hardware also features astounding performance with support for the latest NVIDIA nForce 790i Ultra SLI chipset and DDR3 1333; and provides industry-leading technology in the form of an onboard SAS device for enhanced data transfer experiences.

ASUS EPU for Outstanding CPU Power Savings
The new ASUS exclusive EPU is the world's first intelligent on-demand power saving microprocessor. This intelligent automatic energy saving chip is more stable than software-driven solutions (where stability can be an issue), and provides users with superior performance while in energy-saving mode in comparison to other solutions. By utilizing an innovative power technology, the EPU is able to digitally monitor current CPU usage levels and automatically fine-tune the CPU power supply with improved VRM efficiency to suit any loading. The EPU is thus able to provide users with the ability to moderate power for higher performance if required, or save CPU power under low processing periods for the best possible performance with the least amount of power - achieving industry-leading power savings.

Exclusive HE 95 for Exceptional Power Efficiency
Excellent performance is a mandatory requirement for most workstation users, and it is not likely that their PCs will stay in low-loading modes. ASUS has developed a brand new feature - the HE 95, which can provide 28% enhanced power efficiency during periods where extensive processing like 3D rendering are required. Working hand in hand with the exclusive EPU, this allows users of the P5N64 WS Professional to achieve enhanced power savings in light or heavy loadings. What's more, this new HE 95 feature doesn't require any driver or software, and activates automatically as users switch on their PCs - allowing users to start saving energy immediately.

Onboard SAS for High Performance Hard Disk Operations
The P5N64 WS Professional is also the first channel motherboard to feature the cutting-edge onboard SAS chipset, which supports Serial Attached SCSI (SAS) hard disk. With this technology, SAS hard disks will provide higher data transmission speeds and stronger data storage reliability in comparison to current SATA interfaces; and could herald the dawn of a new age for mainstream storage devices that cater for enterprise users. Utilizing the SAS technology, users of the P5N64 WS Professional will be able to enjoy more reliable, more stable and faster data transfers for storage I/O interfaces than ever before.

NVIDIA Quadro Certified with 3-way SLI Support
The latest chipset of NVIDIA's nForce 790i Ultra SLI- supports 3-way SLI mode, the P5N64 WS Professional also passes the Quadro Certification of NVIDIA. This provides 2D/3D users the best compatible hardware platform for series of NVIDIA Quadro graphic cards. Furthermore, 3-way SLI technique allows users to have more powerful and higher performance when completing sophisticated 2D/3D design works.

Multi-Displays for Effective Multi-tasking
The P5N64 WS Professional is distinctive in its ability to support 4 PCIe x16 slots - which allows users to display a maximum of 8 monitor displays. This is ideal for users who require a large amount of screen and desktop space like CAD/CAM programmers, banking and finance executives and SOHO users.
