If you’re building a PC or upgrading an existing one, you may have come across PCI slots while researching components. PCI slots were once a staple of motherboard design, but they’re becoming less common as newer technologies take their place.
Nevertheless, many modern motherboards still include at least one or two PCI slots. So what can you use them for? Let’s take a look.

Firstly, it’s important to understand what PCI stands for. It stands for Peripheral Component Interconnect, and it’s a type of interface that allows expansion cards to be connected to a computer’s motherboard. These expansion cards can provide additional functionality beyond what the motherboard itself offers.
One common use for PCI slots is to add additional ports to your system. For example, you could install a PCI card with additional USB ports, or one with additional Ethernet ports if you need more network connectivity. Similarly, if your motherboard doesn’t have built-in audio capabilities or if you want higher quality audio than what’s built-in, you can install a sound card in a PCI slot.
Another way to use a PCI slot is to add improved graphics capabilities to your system. While most modern computers have built-in graphics processors on the CPU or motherboard, these are often not powerful enough for demanding applications like gaming or video editing. By installing a dedicated graphics card in a PCI slot, you can significantly improve your system’s graphical performance.
PCI slots can also be used for specialized hardware that may not be available on all motherboards. For example, if you’re building a home theater PC (HTPC), you might want to install a TV tuner card in a PCI slot so that you can watch and record TV on your computer.
Finally, some users may choose to use older expansion cards that only work with older interfaces like PCIe (PCI Express) through the use of adapters that allow these cards to be used in newer systems with PCIe-only slots.
In summary, while the use of PCI slots is becoming less common, they can still be useful for adding additional ports, improved graphics capabilities, specialized hardware, or for using older expansion cards. If you’re building a new PC or upgrading an existing one, it’s worth considering whether a PCI slot might be useful for your needs.
