The ASUS P5NT WS is built on the NVIDIAC55+MCP55PXE chipset structure which supports a LGA775 Socket for running Intel Dual-core/Quad-core CPUs with 1333/1066/800 MHz FSB and two NVIDIA SLI graphic cards with Dual x16 speeds on the same platform. This allows the user to enjoy the best CPU and graphics for the system build. With the addition of the PCI-X interface, the P5NT WS motherboard provides much more options in I/O configurations for SOHOs and power users to custom-build their ideal working or entertainment environment.

High Quality Solid Aluminum Capacitors
The ASUS P5NT WS motherboard is fitted with solid Aluminum capacitors and a conductive polymer to help secure perfect system stability. These high quality materials also help ensure that the motherboard will have a longer product life time.

New PCI-X Structure for More Efficiency
The PCI-X Structure of the P5NT WS motherboard is a newer, higher speed version of the conventional PCI standard. It is also fully hardware and software backward compatible to previous generations of PCI. These new standards keep pace with upcoming advances in high-bandwidth business-critical applications such as Fibre Channel, RAID, networking, InfiniBand Architecture, SCSI, and iSCSI.

Effective Heat-pipe Thermal Solution
The innovative Heat-pipe Thermal design of the P5NT WS motherboard effectively directs the heat generated by the chipsets to the heatsink near the back IO ports - where it can be dissipated by existing airflow from the CPU fan or optional fans. This unique Heat-pipe design highlights how fanless designs effectively curb the problem of chipset fans breaking down.
Furthermore, it provides options for users to install a side-flow fan or a passive cooler. The Heat-pipe design is the most reliable fanless thermal solution to date.

Cool and Quiet 8-Phase Power Design
The P5NT WS also encompasses an 8-Phase Power Design that reduces input ripple current and output ripple voltages - keeping the CPU and power modules from the risk of high power stress. It also provides reliability under heavy-loading and overclocking by
stabilizing output current and voltages. All this effectively lets components attain longer lifespans and allows them to operate at 15°C (36°F) lower than conventional solutions - resulting in lower fan speeds for quieter operation.

ASUS AI Clock Skew - Reliable Overclocking
This helpful feature automatically skews the memory clock signal timing to improve memory overclocking capabilities by 10 to 15%. The clock signal can be adjusted to reserve enough
Setup time / Hold time in order to maintain the system's stability.

Balance Performance and Quietness with AI Gear
ASUS's AI Gear allows users to choose from profiles to adjust the CPU frequency and voltage. This allows a balance for both system performance and quietness. Having two modes: High Performance for running heavy loading applications and Max Power Saving for minimizing system noise and power consumption; AI Gear provides Real-time adjustments under the OS to suit varying needs.

AI Nap - Powersaving and Noise Reducing
With AI Nap, users can instantly snooze the PC without terminating any tasks. The system will continue operating at minimum power and noise till reawakened.
Files will continue to download and applications will be run in the quietest state while the system is in AI Nap mode. The system will swiftly wake up in a matter of seconds with a simple click of the keyboard of mouse.
