A full range APFC will work with input from 90VAC through 264VAC. So yes, you have one hell of a voltage drop from 220VAC before a full range APFC PSU quits.
Europe and asia are said to have a fair number of 220V-only APFC units, which are a different story entirely. I haven't seen one personally, just 220V/240V-only PPFC or no-PFC.
