This adapter is designed to convert any 6-pin power supply PCI Express cable to an 8-pin PCI Express. The 6 to 8-pin PCI-E adapter is ideal for newer video cards that need the new 8 pin PCI-E connector and for those with older generation PSUs.

This is used to convert 6-pin PCI-E connector to 8-pin PCI-E 2.0 connector, normally PS is at least 500W to qualify for the conversion.
