If you’re wondering what PCI slots you have on your computer, you’re in the right place! PCI (Peripheral Component Interconnect) slots are used to connect expansion cards to your motherboard. These cards can be used to add new functionality, such as a dedicated graphics card or a sound card.
There are several different types of PCI slots, each with its own capabilities and limitations. In this article, we’ll take a closer look at the different types of PCI slots and how you can determine which ones you have on your computer.

PCIe Slots
PCIe (PCI Express) is the most common type of PCI slot found on modern motherboards. PCIe slots come in different sizes, including x1, x4, x8, and x16.
The “x” stands for the number of data lanes that the slot has. The more lanes a slot has, the faster data can be transferred between the expansion card and the motherboard.
PCIe slots are typically used for high-speed devices such as graphics cards and solid-state drives (SSDs). If you’re building a gaming PC or workstation, you’ll likely need at least one PCIe x16 slot to accommodate a high-end graphics card.
PCI Slots
The original PCI standard was introduced in 1992 and has since been largely replaced by PCIe. However, some older motherboards still have one or two PCI slots available for use.
PCI slots are typically slower than PCIe slots and are limited to a maximum bandwidth of 133MB/s. This makes them unsuitable for high-speed devices such as graphics cards or SSDs but they can still be useful for connecting legacy devices such as sound cards or modems.
AGP Slots
AGP (Accelerated Graphics Port) was an older type of expansion slot that was specifically designed for graphics cards. AGP slots were faster than standard PCI slots but were eventually replaced by PCIe.
If you have an older computer, you may still have an AGP slot available. However, it’s unlikely that you’ll find any modern graphics cards that are compatible with AGP slots.
Identifying Your PCI Slots
So, how can you determine what type of PCI slots you have on your computer? The easiest way is to check your motherboard manual or visit the manufacturer’s website. They should have a detailed specification sheet that lists all of the expansion slots available on the motherboard.
If you don’t have access to your motherboard manual or can’t find the information online, there are a few other ways to identify your PCI slots. Firstly, you can physically inspect the motherboard and look for the different types of expansion slots. PCIe slots are typically longer than PCI or AGP slots and are usually located closer to the CPU socket.
You can also use software tools such as CPU-Z or Speccy to identify your hardware components, including your motherboard and its expansion slots.
Conclusion
In summary, there are several different types of PCI slots available, including PCIe, PCI, and AGP. PCIe is the most common type of expansion slot found on modern motherboards and is typically used for high-speed devices such as graphics cards and SSDs. Older computers may still have one or two PCI or AGP slots available for use with legacy devices.
To determine what type of expansion slots you have on your computer, check your motherboard manual or use software tools such as CPU-Z or Speccy. With this information in hand, you can ensure that any new expansion cards you purchase are compatible with your system’s hardware.
