ENERGY USING PRODUCTS 2013

Conformité_Européenne(logo)Energy Using Products (EuP) 2013 is a EU directive 2009/125/EC.

The previous directive for energy using products only covered products that used energy, such as washing machines or computer. The new ErP-Directive covers products under the old EuP Directive as well as products that are energy-related and do not directly use energy such as water-saving taps and showerheads.

The 2013 standard says that a device, when turned off shall consume no more than 0.5 Watts of electricity.

In the case of a computer, both the motherboard and power supply are required to meet the standard, where the motherboard meets the 0.5W requirement, and the PSU must have a 5V standby power efficiency higher than 50% when drawing under 100 mA of current in order to be considered ErP/EuP compliant.

Motherboards and BIOS support started offering EuP which Windows 10 and above can support to provide better power management for desktop and mobile machines.

A machine that is in sleep mode (S3) should be under 0.5W to be compliant.

Energy Using Protocol is the initiative introduced by the EU to reduce PC idle power consumption. The stated goal is ½W which is also now being adopted by California. Laptop and desktop machines are generally powered continually so efforts towards overall power consumption have been ambitious. Wall chargers are notoriously inefficient.

Work published by the IEEE generally focused on battery powered devices that are becoming more common. Today the wireless networking is the biggest consumer of power for mobile. Additional work by the Bluetooth group are looking at power.

Our MSI 9701-G43 supports EUP 2013 in the BIOS. This configures unused devices to reduce more power when the machine is idle. We use Corsair power supplies which have long fully support energy initiatives. Some cheaper models power supplies may have issues with EUP 2013 in the BIOS.

Our Asus M5A99FX PRO R2.0 has a similar option that they call EPU. Asus marketing has long pushed the improvements with their motherboards.

Laptop machines usually do not offer as rich of options as desktop machines. For this reason we like the MSI approach which they call Click BIOS. The entire UEFI BIOS is manageable from within Windows which makes checking settings easier.

USB wall chargers are slowly becoming more efficient as new designs are instroduced. Low cost generic 5W chargers are mass prduced but these units have very poor 60% efficiency. The Apple A1265 charger is much more efficient ay 74%. Our 12W Belkin charger manages 70% efficincy.

Using a USB 3.0 port on a desktop PC with an 80 PLUS platinum PSU will be dramaictally more efficient. At home the PC can be used for gaming or web browsing while efficienctly chargng a mobile phone.
