    What is EuP/ErP?

    What is EuP/ErP?

    Some you of might have noticed your motherboard or power supply boasting something called EuP or ErP 2.0 LOT 6.

    You can ready about it here.
    Ecodesign - Sustainable and responsible business - Enterprise and Industry

    ErP Lot 6 is a directive of ErP regulation in the category of ‘Standby and
    off-mode losses of ErPs’ to define the Standby and/or off mode. ErP Lot 6
    requires that <0.5W Standby (S5) no WoL beginning in 1H 2013.
    PCs that are
    placed on the market by (ie, leaving the manufacturer) on or after that date must
    meet ErP Lots. An ErP Lot 6-ready power supply is needed to ensure the system
    will consume less than the requirement.
    Essentially, the aim of EuP/ErP is to reduce 'Phantom' / Standby Power draw.

    How is this achieved?

    Reducing the standby power requires a combination of
    1) EuP/ErP Ready Motherboard
    2) EuP/ErP Ready Power Supply Unit

    Today I'm going to test with
    1) Biostar TP67B+ (This board can turn on/off EuP/ErP compliance through its BIOS)
    2) FSP Aurum 400w 80+ Gold (EuP/ErP Ready)
    3) Corsair VX550 80+ normal (Not EuP/ErP Ready)

    The 2 power supplies featured today.

    My simple test system.

    The results easily show the difference between the less efficient standby design of
    the Corsair VX550 and the newer more efficient one of the FSP Aurum 400.

    The difference at the end of the day might only be 1-2w and over the course of a
    whole year, it might only save you less than $2 in total electrical savings.

    But multiply this savings by a whole nation or in the case of Europe, a whole
    continent, and you'll have a very sizeable savings.

    Standby consumes approximately 50 TWh electricity per year in the EU, and
    the regulation will trigger a reduction by 73% by 2020. The savings are comparable
    to Denmark's yearly electricity consumption
    , and correspond to approximately 14 Mt
    of avoided CO2 emissions.
    It'll be good to note that all new Intel LGA1155 motherboards are now EuP/ErP
    ready but not all power supplies on the market are ready.
    In Europe, EuP/ErP compliance is mandated but not locally (as it does cost
    more to implement over older designs )though you will be able to find products
    that comply with this standard.

    So if you do decide to go greener, look out for ErP/EuP compliance (you shouldn't pay more for it though) from the
    motherboard and power supply that you buy.

    Thanks for the info man. really appreciate what u did. I mean the insight sure is intruding .
    Never agree on the UNAGREEABLE MATTERS!!!
