Enermax Power Supplies Support Forthcoming Haswell CPUs

by Hilbert Hagedoorn on: 04/30/2013 12:07 PM | source: | 6 comment(s)

Intel has just released more details about the new Haswell proccessors. 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 manufaacturers 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.

Ready for future Intel® Haswell CPUs due to ZERO Load Design:

Most of BeQuiet! PSUs have Zero load design.
I don't think it's big deal.

Question is , how the Haswell cpu will work on PSU That doesnt support Zero load design.

I can only assume the CPU just simply unable to enter C6/C7 state (which is a moot point for most desktop systems) rather than being non-operational.

I think most of the newer PSU's shouldn't have any problems.

intel would barely sale Haswell if it required all new PSU. nonetheless they stated that adoption rate will be slow, but seriously unless they OC performance can gain 50%+ performance over Sandy Bridge, then i upgrade if not then sb for life!
