Enermax Power Supplies Are Ready For New Haswell CPU Sleep States

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 750W (EPM750AWT)
    • Platimax 850W (EPM850EWT)
    • Platimax 1000W (EPM1000EWT)
    • Platimax 1200W (EPM1200EWT)
    • Platimax 1500W (EPM1500EGT)
  • Enermax Revolution87+ Series
    • Revolution87+ 550W (ERV550AWT-G)
    • Revolution87+ 650W (ERV650AWT-G)
    • Revolution87+ 750W (ERV750AWT-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)
    • Triathlor 450W (ETA450AWT)
    • Triathlor 550W (ETA550AWT)
  • Enermax Revolution85+ Series
    • 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!

Press Release:

"Enermax power supplies are ready for forthcoming Intel® Haswell™ CPUs
Zero Power – Stable Voltages

May 2nd, 2013, Taoyuan, Taiwan. Intel® has just released more details about the new Haswell™ processors. It sets new benchmarks in terms of energy efficiency. The new C6 and C7 states are able to reduce the CPU power consumption to just 0.05A while previous Ivy Bridge processors draw up to ten times more minimum power.

But the positive progress of the CPU technology is subject to certain restrictions, because only few power supplies will be able to deliver stable voltages at such low loads. End users are therefore groping in the dark with no clues if their own power supply will be compatible with the new energy functions of Intel® Haswell™ CPUs. PSU manufacturers usually do not state the possible minimum load of their products.

http://www.enermax.de/presse/2013/Zero-Load.jpg Compatibility of Enermax Power Supplies
As one of the technologically leading power supply manufacturers, Enermax makes a step forward and publishes a PSU compatibility list. All current high-end and mid-range models from Enermax are already prepared for the upcoming Intel® processors. They are equipped with a DC-to-DC converter which enables the so-called ZERO Load Design. These power supplies will deliver rock-stable voltages even at 0W load. Also the owners of older Enermax power supplies can be relieved: The manufacturer applies the ZERO Load Design already in all high-end power supplies since the Revolution85+ series which has been launched in 2008.

Is there an official intel list showing which PSU's are compatible?

I currently have a Corsair HX750 and was thinking of using that for next upgrade/Haswell build.

A link would be divine.

For resellers(not all PSU there):
http://www.intel.com/reseller/psu_selector/

Third last column is correct filter. According to that table, looks like your PSU is fully compatible.
