List of Power Supplies Compatible with Intel Haswell CPUs

The next generation Intel Core processors, codenamed Haswell, offers promising features like super power efficiency, much better integrated graphics processor and expected to be more powerful than the previous CPUs. Because the Intel Haswell can operate on a very low power consumption this is a problem with the current power supply lineup that manufacturers produce. According to Intel Haswell’s C6 and C7, it requires that a minimum load of 0.05 amps on the 12V2 rail. But the problem is, some if not most, PSUs can’t operate on such a very low power, or they can’t deliver a stable and low power output. I’m sure you are wondering if your PSU can handle Haswell, so below is a list of PSUs that are confirmed to be compatible with Haswell processors.

List of Power Supply Compatible with Haswell Processor

UPDATE: I have updated the list and more manufacturers have already announced which PSU are Haswell compatible.

As of to date, only Enemax has confirmed that some of their models are ready for Haswell. But I’m sure popular PSU manufacturers like Corsair, Silverstone and others will have PSUs compatible with Haswell. Check the list below.

Seasonic Power Supplies Compatible with Intel Haswell Processor

Seasonic didn’t made a more detailed list, but according to their press release the following Seasonic PSU series are ready for Intel Haswell:

Our full lines of 80 PLUS Platinum and Gold power supplies have been designed to be ready to meet Haswell’s new technical requirements! The ultra efficient Platinum series, which also includes the industry leading true fanless models, and our long running, award winning X Series, which is now supported by the 80 PLUS Gold G series – are all Haswell READY! In addition, our 80 PLUS Bronze line up, consisting of the M12II-750 & 850W models, is also compatible to be used with Intel’s new Haswell Processors.

For now, the above PSUs are the confirmed units that will be compatible or ready with Intel Haswell processors. I’ll continue to update this post once other manufacturers have also confirmed what PSUs of theirs are compatible with Haswell.

Cooler Master Power Supplies Compatible with Intel Haswell

Cooler Master recently released a press release regarding their PSU lineup that are compatible with Haswell. I’ll list them down below, but before that, check out what Cooler Master has to say about this whole compatibility issue. There are some misconceptions and things that the public should be aware of that Cooler Master wants us to know. Here’s an excerpt from their PR.

  • Most power supplies don’t support Haswell – False
  • I need a Haswell certified power supply to build a Haswell system – False
  • Haswell only works with DC-DC Power Supplies – False
  • Haswell only works with 80+ Gold and better Power Supplies – False
  • Haswell requires a second 12V rail and doesn’t work with single rail Power Supplies – False
  • On some older power supplies, Haswell consumes 5W more in idle mode – True

Among other improvements of Intel’s latest Core Processors, power consumption in idle mode has been greatly reduced from around 6W to less than 1W. This might cause some older power supplies to shut the system off when the CPU enters idle mode, or prevent the system from waking up out of sleep mode. To our knowledge all mainboard vendors will disable this advanced power saving mode by default, and no customer upgrading to Haswell should experience any issues whatsoever.

Nevertheless, should customers experience problems or would like to enable the advanced power saving mode on older power supplies that might not support it, there is a simple fix. Simply add a single silent case fan to the system and connect it to the power supply. It should provide enough additional load to keep the system running in an advanced power saving mode.

The only disadvantage would be that power savings in idle mode on such a system would only amount to around 2-3W instead of ~5W.
