I would say around 80% of the current Haswell certified PSUs are pre-Haswell. So, I guess most recent quality PSUs would work with Haswell.
However, there is of course no guarantee. But it should work fine.
I just saw a link:
http://coolermaster-usa.com/press_release/haswell/haswe...

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
That's what they say...

Basically,certified,Haswell ready PSU means, that PSU sure will power up your Haswell system. But the others,there exist doubts...though it doesn't mean they won't...Just not completely sure...

From what I know Haswell has a really deep sleep state. Any PSU should be able to power Haswell. But if you choose to use the sleep function in windows if your PSU handle the low load it will reboot. If you don't use sleep this won't be an issue.

Edit: Let me try this again...
