The breakthrough technology of 16+2 phase VRM design is bringing to the
ASUS motherboards. 16+2 phase power design (16-phase to vCore; 2-phase to
vDRAM/QPI controller inside CPU) can reach high power efciency, dispel heat
generated by VRM module effectively, and lower more temperature compared to
other VRM solution. With the high quality power components such as low RDS (on)
MOSFETs, Ferrite core chokes with lower hysteresis loss, and 100% Japan-made
high quality conductive polymer capacitors, ASUS 16+2 phase VRM design also
ensure longer component life, minimum power loss, and help to reach the superior
overclocking score ever than before.

1-4 Chapter 1: Product Introduction
ASUS Workstation Features
ASUS Workstation features provide complete support to system maintenance and
storage technology.
True @16 3-Way SLI
The Best Graphic Performance you EVER have
The True @16 PCI-E Gen2 3-Way SLI will present you the fastest and the
most reliable graphic performance you ever have when you are engaged in
Mechanical/Architecture/Interior/Aircraft/Audio/Video Design or when you are
playing games in leisure time
Diag LED
Diag LED checks key components (CPU, DRAM, VGA card, and HDD) in
sequence during motherboard booting process. If an error is found, the LED
next to the error device will continue lighting until the problem is solved. This
user-friendly design provides an intuitional way to locate the root problem
within a second.
Built-in Dual Intel Server-Class Gigabit LAN
For more reliable networking, the P6X58-E WS features built-in dual Intel
server-class Gigabit LAN. It uses lower CPU utilization, increasing throughput
to achieve outstanding performance as well as better support for diverse
operating systems.Besides,Intel® 82574L chipset has certication of VMware
to support virtualization technology.
G.P. Diagnosis card
Bundled with P6X58-E WS motherboard (retail version), the G.P. Diagnosis
card assists users in system checking by effortlessly and quickly providing
precise system checks right after they switch on their PCs.
ASUS Power Saving Solution
ASUS Power Saving solution intelligently and automatically provides balanced
computing power and energy consumption.
ASUS EPU
The new ASUS EPU—the world’s rst power saving engine, has been
upgraded to a new 6 engine version, which provides total system power
savings by detecting current PC loadings and intelligently moderating power
in real-time. With auto phase switching for components (which includes the
CPU, VGA card, memory, chipset, hard drives and CPU cooler / system
fans), the EPU automatically provides the most appropriate power usage via
intelligent acceleration and overclocking - helping save power and money.
