Some 3.3v cards pull power from the 5v rail and convert it to 3.3v in order to get a "cleaner" or more accurate 3.3v than what the PCI Spec (and some vendors) provides. And for PCI 2.1, 3.3v power rail is optional. That turned into a requirement for PCI 2.2 compliance. (Caveat: this is all second hand info - I'm a SW dork - not HW eng. but I believe it's correct.) grant
