This patented ASUS technology lets you use your existing power supply rather than buying a new ATX 12V power supply. The ASUS EZ Plug™ is a 4-pin auxillary +12V connector mounted on the motherboard that connects a regular 4-pin device power connector from the power supply. This connector is necessary to provide the additional power required by the P4 CPU.

ASUS MyLogo™

This new feature present in the P4B-E motherboard allows you to personalize and add style to your system using customizable boot logos.

Digital audio interface

On audio models, a digital audio connector is onboard to accommodate the bundled Sony-Philips Digital Interface (SPDIF) In/Out module, which supports coaxial and optical interfaces. Experience 5.1-channel surround sound and enhanced 3D audio while playing your favorite DVDs and computer games.

RAID 0/RAID 1 support

The motherboard includes the Promise® chip PDC20265R and two extra Ultra ATA/100/66 interfaces to support Redundant Array of Independent Disks (RAID) configuration. This feature requires UltraATA 100/66/33 hard disks. The RAID chip onboard supports RAID 0 and RAID 1 configurations.

RAID 0 (called data striping) optimizes two identical hard disk drives to read and write data in parallel, interleaved stacks. Two hard disks perform the same work as a single drive but at a sustained data transfer rate, double that of a single disk alone, thus improving data access and storage. RAID 1 (called data mirroring) copies and maintains an identical image of data from one drive to a second drive. If one drive fails, the disk array management software directs all applications to the surviving drive as it contains a complete copy of the data in the other drive. This RAID configuration provides data protection and increases fault tolerance to the entire system.
