VIA Introduces New pc3500 Mainboard

Enables OEMs and SIs to build most energy-efficient Windows Vista PCs that draw over 50% less power than the latest Energy Star requirements

Taipei, Taiwan, Tuesday 21st August 2007 – Further strengthening its leadership in providing the world’s most energy-efficient computing platforms, VIA Technologies, Inc. today announced the VIA pc3500 Mainboard, a low power, feature-rich platform that enables OEMs and System Integrators to build Windows Vista desktop PCs that draw less than 24 watts in Idle State – less than half the requirement of the U.S. EPA’s latest Energy Star Program Requirement for Computers: Version 4.0.

In addition, a system based around the VIA pc3500 Mainboard draws only 1.09 watts in Sleep Mode, and 0.68 watts in Standby (Off Mode), comfortably meeting the Energy Star requirements for a Category A system, as summarized in the table below. The system even draws under 35 watts when playing back a DVD, one of the most power-intensive computing applications.

Mode Energy Star Category A Requirements VIA pc3500 Mainboard System
Standby (Off Mode) ≤ 2.0W 0.68W
Sleep Mode ≤ 4.0W 1.09W
Idle State ≤ 50W 23.62W
DVD Playback N/A 34.48W

“With the launch of VIA pc3500 mainboard we are leading the way in developing innovative low power platforms that enable our OEM and SI customers to meet the growing worldwide demand for energy-efficient PCs,” commented Richard Brown, Vice President of Corporate Marketing, VIA Technologies, Inc. “Consumers and business users who purchase PCs based on the VIA pc3500 mainboard will not only be able to significantly reduce their energy costs but also minimize their environmental impact while running all the latest software applications.”
