Cooler Master also proposes a workaround for PSUs that may lack support:
Should customers experience problems nevertheless, 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 adding a single silent case fan to the system, connected to the power supply, should provide enough additional load to keep the system running in advanced power saving mode. The only disadvantage would be that power savings in idle mode on such a system would only surmount to around 2-3W instead of ~5W.
Hmm. Interesting.

XFX
Here's the word from XFX on Haswell compatibility:
XFX power supplies use a +12V design that allows for a minimum of 0A so they will not have an issue with the new low power sleep states allowing the CPU to enter deep sleep mode without any problems. XFX manufacturing partner Seasonic in conjunction with Intel have worked together to confirm that all XFX Pro Series PSUs listed below are compatible with Intel's new 4th generation Core processor family for new CPU upgrades to current systems and future new builds.
And here's the compatibility list:
Pro Series Core Edition: PRO650W, PRO750W, PRO850W
Pro Series XXX Edition: PRO650W, PRO750W, PRO750W, PRO850W, PRO850W
Pro Series Black Edition: PRO750W, PRO850W, PRO1050W, PRO1250W
Pro Series Black Edition: Limited PRO1000W
The firm adds that its XFX Pro Series 450W and 550W units are not Haswell-ready. However, XFX is "working closely with Seasonic to develop a new 550W Gold Pro Series PSU that will be compatible later this year."
got this from another website and is what I used when choosing my PSU.
