With the changeover to PCI Express, there are actually only the 6-pin and 8-pin PCIe power connectors for current graphics cards. The 4-pin connector, used by older drives, is only employed by graphics cards using the AGP interface.
The most powerful graphics cards are equipped with 6-pin and 8-pin power connectors on the power supply.
Since not all power supplies are equipped with PCI Express connectors, many name brand manufacturers of graphics cards include the necessary adapter. Today, you can pretty much get every adapter needed to be compatible with 6-pin or 8-pin power connectors.
