Agppci Card

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. AGP cards and PCI cards have different connectors, so you cannot insert a PCI card into the AGP slot.

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

The AGP video card, installed in slot 1, contains the graphics processor unit (GPU) and provides the computer's display ports. Slot 1 is designed specifically to accept AGP cards.

PCI Cards

The remaining three expansion slots, labeled 2, 3, and 4, accommodate PCI cards up to 12 inches long.

Note: Certain high-performance AGP graphics cards, when installed in slot 1, block access to the adjacent PCI slot. In this case, PCI cards can be installed in slots 3 and 4 but not in slot 2.

The only tool required for this procedure is a Phillips screwdriver.

Preliminary Steps

Before you begin, open the computer and lay it on its side with the access side facing up.

Part Location

Install an AGP video card in slot 1 only. Install either PCI or PCI-X cards in the slots labeled 2, 3, and 4.

Warning: When removing or installing a PCI or AGP card, handle it only by the edges. Do not touch its connectors or any of the components on the card. Lift the card straight out from the connector to remove it, and insert it straight into the connector to install it. Do not rock the card from side to side and don't force the card into the slot. Once the replacement card is installed, pull on it gently to check that it is properly connected.

  1. Remove the screw that mounts the card to the enclosure.
  2. If you are removing an AGP card, pull back the small locking clip at the front of the AGP connector.
  3. Holding the card by the top corners, gently pull up the card and remove it from its expansion slot.

Replacement Note: Align the card's connector with the expansion slot and press until the connector is inserted all the way into the slot. If you're installing a 12-inch card, make sure the card engages the appropriate slot in the PCI card guide.

  • Don't rock the card from side to side; instead, press the card straight into the slot.
  • Don't force the card. If you meet a lot of resistance, pull the card out. Check the connector and the slot for damage or obstructions, then try inserting the card again.
  • Pull the card gently to see if it is properly connected. If it resists and stays in place, and if its gold connectors are barely visible, the card is connected.
