EuP Ready Motherboard EuP Ready Power Supply EuP System

What is EuP?

EuP, stands for Energy Using Product, was a provision regulated by European Union to define the power
consumption for the completed system. With the great quantity and the popularly using of the electrical products
nowadays and the continuously increasing of the electrical products categories in the following 20 to 30 years,
European Union decided to establish an effective strategy to solve the energy consumption problem. That is,
according to EuP, the total AC power of the completed system shall be under 1.00W in off mode condition.

ATI Radeon® HD4200 DirectX 10.1 Onboard Graphics

Key features of DirectX 10.1 include an updated shader model, improved anti-aliasing support, more flexible data access,
and tighter specifications for better applicationcompatibility.

DirectX 10.1 Anti-Aliasing

DirectX 10 –Standard
MSAA:Foliage edges do not
get anti-aliased –causes
shimmering and crawling
when they move

DirectX 10.1 –Alpha Test
MSAA:Foliage edges are
smoothed and anti-aliased
–offers significant image
quality improvement
