Noise Level Data
VIA and the EPIA series have been at the forefront of the quiet computing initiative.
The EPIA V–Series has been designed to be totally non-obtrusive with noise levels
equivalent to a person whispering. With noise levels ranging from the totally silent
EPIA VE5000 to 25dBA for the EPIA V10000, a new wave of system design
innovation and exciting opportunities are being created in an almost limitless number
of emerging new market segments - ranging from silent running mini-PCs and living
room digital media entertainment centers to Car PCs and a host of embedded
applications such as Kiosk, POS, and Industrial Control machines.

The dBA scale is logarithmic, i.e. 10 dBA represents a doubling in volume. dBA values are measured at a
distance of one meter.
Power Consumption Data
The following graphs are a comprehensive comparison of power consumption results
for a range of typical PC applications with the VIA EPIA V-Series mainboards
compared to the typical “one size fits all” platform that is being promoted by others
in the PC industry. We have also included the EPIA M10000 mainboard as a frame of
reference.
The “one size fits all” system that we are using as a reference platform is an Intel
845-based Pentium 4 platform and we are comparing the power consumption to that
of the VIA EPIA V-Series Mini-ITX mainboards. All tests were conducted using the
Microsoft Windows® 2000 operating system and include the wattage consumed by
the total platforms.
