How PCI Cards Differ From One Another

Building a computer isn't all that hard, but there are a few parts that can be confusing. When you start installing PCI cards — video cards, network cards, and other expansion cards — it's hard to know which kinds of cards are compatible with your motherboard. Linus Sebastian from Techquickie fills us in.

You've probably seen many different types of PCI cards and slots: PCI, PCI Express, PCI Express 3.0, 1x cards, 16x cards, and so on. Techquickie runs through everything you need to know about PCI as fast as possible, so you'll never be confused again. We'll leave it to the video to explain it all, so check it out above.

PCI Express (PCIe) 3.0 - Everything you Need to Know As Fast As Possible [Techquickie]


    In a jam you can cut the connector down on certain cards to fit a certain slot (Don't blame me if you get it wrong). I cut the end of my dual NIC card to fit in a PCIe x1 slot on my HP Microserver!

      This is a universally bad idea. It might work, it probably won't, and it might permanently damage the motherboard. The PCI specification requires different combinations of pins be short-circuited to notify the controller of its size and those pins are not always located in the part you're cutting off.

      If you must use a PCI card in a PCI slot that won't support it, use an adapter. Here's what one kind looks like:

        I've cut PCI cards before, an adapter is better but if your cbf and its not a valuable system/component - it'll probably work.

          Did you reconnect all the ground pins you cut off as well? If not, every time the card is powered it risks damaging the components both on the card and on the motherboard itself. There are ground pins in every block, usually two or three at a time.
