Earlier this week, it was revealed that Intel’s upcoming Haswell processors would feature new C6 and C7 sleep states that draw as little as 0.05A on the 12V rail. Such low power draw on the 12V rail may cause problems for existing power supplies, which are not accustomed to facilitating such low power draw (especially on the 12V line). In an attempt to clear up a bit of the confusion for its customers, Enermax has put together a list of its mid-range and high-end power supplies that meet the standards required to support the new low-power processor states.

According to the press release (seen below), the Enermax power supplies use so-called Zero Load technology that uses a DC to DC converter to support low wattage power draw. This technology has been in Enermax power supplies since the Revolution85+ series which was launched in 2008. The company claims that the power supplies deliver “rock solid voltages” down to 0W load, which is within the Intel specification of 0.05A for the CPU alone.

The list of compatible Enermax power supplies is as follows:

  • Enermax Platimax Series
    • Platimax 500W (EPM500AWT)
    • Platimax 600W (EPM600AWT)

    • Platimax 850W (EPM850EWT)
    • Platimax 1000W (EPM1000EWT)
    • Platimax 1200W (EPM1200EWT)
    • Platimax 1500W (EPM1500EGT)
  • Enermax Revolution87+ Series
    • Revolution87+ 550W (ERV550AWT-G)
    • Revolution87+ 650W (ERV650AWT-G)

    • Revolution87+ 850W (ERV850EWT-G)
    • Revolution87+ 1000W (ERV1000EWT-G)
  • Enermax MaxRevo Series
    • MaxRevo 1200W (EMR1200EWT)
    • MaxRevo 1350W (EMR1350EWT)
    • MaxRevo 1500W (EMR1500EGT)
  • Enermax Triathlor Series
    • Triathlor 385W (ETA385AWT)

    • Revolution85+ 850W (ERV850EWT)
    • Revolution85+ 920W (ERV920EWT)
    • Revolution85+ 950W (ERV950EWT)
    • Revolution85+ 1020W (ERV1020EWT)
    • Revolution85+ 1050W (ERV1050EWT)
    • Revolution85+ 1250W (ERV1250EGT)
  • Enermax Modu87+ Series
    • Modu87+ 500W (EMG500AWT)
    • Modu87+ 600W (EMG600AWT)
    • Modu87+ 700W (EMG700AWT)
    • Modu87+ 800W (EMG800EWT)
    • Modu87+ 900W (EMG900EWT)
  • Enermax Pro87+ Series
    • Pro87+ 500W (EPG500AWT)
    • Pro87+ 600W (EPG600AWT)

The list includes power supplies from a number of series over the past few years that range from 500W to 1250W. I'm sure between now and the launch of Haswell in the first week of June that other PSU manufacturers will be announcing which models are compatible and which are not. Stay tuned to PC Perspective as more information becomes available!
