Since Haswell is going to be so power efficient and uses so little power at idle the discussion in some other places has been that some power supplies aren't able to run a Haswell CPU because they cant deliver clean power at such low power. 

 

If you are planning on a new Haswell PSU is that something you need to check before purchace of a PSU? Does it need to have a certification "Haswell Ready" or something?! 

 

I saw this (link above) on a hardware site in my country that CM in this one claimes that theirs are ready for it. In the item it also mentioned Corsair and other brands... 

 

What are your thoughts on this? All (not dino age PSUs) from a decent brand will be good for a Haswell system and no need to check for a Haswell Ready thingy?

 

Maybe some specs important? Singlerail? Or anything above 80+ xxxx certification?

It's a power saving setting that's disabled by default in your BIOS. So unless you enable it any powersupply will work. No need to upgrade your PSU.
