It is true. The Haswell platform introduced two new C states, C6 and C7 which allow the PC to sleep on about 0.05A and the PSU has to be able to recognize it otherwise it will shut down thinking the board has no power at all.
Most good, well built PSUs are fine. I also disabled all the C states.
By the way, I don't even know what a C State is.
Some info.

Like Gary said, most well built, decent power supplies support the Haswell architecture. Also, quite a few PSU's that are Haswell compatible will say so in the description. If you need a recommendation, just let us know.

C-States are advanced CPU current lowering technologies. These are configured in the BIOS and are automatically used by the OS.
