Sea Sonic and Corsair Power Supplies Certified for Haswell
 

The Haswell launch gets just a little more complicated each day, with the latest wrinkle being that standard ATX power supplies that conform to the ATX 2.3 standard may not actually be capable of supporting Haswell's extremely low power sleep states. The result has been power supply manufacturers scrambling to see if their power supplies can handle Haswell's requested 0.05A on the 12V rail as opposed to the ATX 2.3 minimum's 0.5A.

Both Corsair and Sea Sonic have been rigorously testing their power supplies to determine which ones definitely can handle Haswell's C6/C7 states, and both have a list of power supplies which are certified to run Haswell, and in the case of Corsair and their substantial portfolio, which power supplies should be able to handle Haswell with no problems.
