- PCI Express power cable: This is the cable that goes to the PCI Express cards
(e.g. graphic cards). Some graphic cards have 6 pin PCI Express power
connectors and others have 8 pin connectors. Many power supplies come with
a 6+2 PCI Express power cable which is compatible with both kinds of
graphic cards. The 6+2 PCI Express power cable is made up of two pieces: a
6-pin piece, and a 2-pin piece.
