Following news that not all power supplies will support the new C6/C7 power states of Intel's Haswell processor, Enermax published a list of its power supplies that fully support the new C6 and C7 states.
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.
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.

In related news, The Tech Report heard from Corsair that the company is working to ensure that all of its power supplies support the C6/C7 states. The company believes its PSUs already do but are checking to confirm.
