Possible to install a PCI express video card into a PCI video slot?

I've never replaced my video card before So, just curious...|||Absolutely incompatible! There is also no adapter or riser card. The PCI bus is much slower than x16 PCIe graphics. The PCI slot is only capable of supporting up to 25 watts power draw. x16 PCIe slots support up to 75 watts power draw (150 watts in PCIe 2.0). Thus, it was never even practical to adapt PCIe cards on the slow PCI slot.



In the case of current AGP cards, they are actually PCIe cards by design. A bridge chip is added then an AGP connector is used.|||No, you can only install a PCI-E card into a PCI-E slot. A PCI-E card wont even physically fit into a normal PCI slot. You can however buy a PCI video card for your PCI slot.|||Nope. They are completely different slot types.



PCI can only fir into PCI, and PCIe can only fit into PCIe.|||No, the connectors are different. Most motherboards these days have both slots though. Refer to your documentation, or open your case and verify before buying one or the other.
