Enermax Modu 82+ II 525W (ErP Lot 6) Power Supply Review

Rating: 9.0.

Enermax are highly respected in the enthusiast community, especially for their high quality power supplies. Today we are looking at an update on their new Modu 82+ II 525W unit, which adds EU regulation ‘ErPLot6’ compliancy.

These new revisions are being rolled out in 2011 to meet the new guidelines and the 525W model will be available from March 2011 onwards for around £100 inc vat. This is an 80 Plus Bronze unit with a reported 84%-88% efficiency.

So why another revision? ErP (Energy-related product) is a new directive to establish a framework for the setting of eco-design requirements. All products must meet the ecology design requirements and obtain the ‘CE’ certification. Only then, can the product be sold into the EU market.

ErP Lot 6 (previously EuP = Energy-using Products) is part of the EU FrameWork Directive on Eco-Design of Energy Using Products from the 21st of October 2009. A new regulation (no 1275/2008) states that from the 7th of January 2010 a PC system should not consume more than 1W during off state or standby. From the 7th of January 2013 the limit will change to 0.5W. In the future, only systems which meet this requirement will receive CE certification.

To meet this requirement a PSU is only part of the equation, the motherboard also has to be compliant, ultimately reducing power consumption and meeting the ErP Lot 6 demands. In the case of a power supply, the standby consumption depends on the efficiency of the 5V standby rail (5Vsb).

Enermax say “We improved the efficiency of the 5V standby rail to make its PSU ready for the newest EU standard. We gained around 20% efficiency on the 5Vsb rail – up to 55% instead of around 35% (0,09A load, 230V). The first models will be launched at the beginning of 2011 – series by series, starting with Pro82+ II and Modu82+ II. Enermax is one of the first PSU manufacturers to react on this regulation.”

    Fantastic product. Only gripe for me is the price. I understand if it was gold certified, but seems a bit steep for bronze. even with the new standby power saving mode.

  • Jim

    I have the older version of this supply and it has been a great workhorse for me. I have actually built a crossfire system around it with two 5770s and it was great.

  • Jullian

    Its always good to see companies focusing on power consumption, its very important. Well it is for me anyway.

  • Tech Head

    Enermax are one of the few companies who design their own power supplies AND build them. for this alone I give them a lot of credit. I know many people prefer Antec or Corsair, but I always buy Enermax. never had any problems or failures.

  • Ben

    Very nice indeed, bit expensive though for the output.

  • Seth

    I like enermax power supplies, but im not sure 525w is offering much futureproofing. id aim for high quality 850w this time minimum.

  • Tech Head

    @ Seth. I think people get caught up with wattage output figures. unless you want to run multiple GFX there is no need for anything more, this will handle even a GTX580 and high end CPU without a problem. Worth thinking about !

    Education on the new energy standards, thanks. Shame they couldnt get this rated at silver 80 plus, but its pretty close.
