Note: Certain high-performance AGP graphics cards, when installed in slot 1, block access to the adjacent PCI slot. The remaining three expansion slots, labeled 2, 3, and 4, accommodate PCI cards up to 12 inches long. Slot 1 is designed specifically to accept AGP cards. The AGP video card, installed in slot 1, contains the graphics processor unit (GPU) and provides the computer's display ports. Note: Maximum power consumption for all four expansion slots (the three PCI expansion cards and the AGP card) should not exceed 90 watts (W). AGP cards and PCI cards have different connectors, so you cannot insert a PCI card into the AGP slot.
Power Mac G5 computers have four expansion card slots, three of which accommodate Peripheral Component Interconnect (PCI) cards and one that accepts an advanced graphics port (AGP) video card.
