PCI Express (PCIe) is a high-speed expansion card interface standard for personal computers. It is the successor to the PCI and AGP standards and provides much higher bandwidth and lower latency. PCIe is used for a variety of devices, including graphics cards, network cards, and storage controllers.
There are a few different ways to check if your computer has PCIe slots. One way is to look at the motherboard. PCIe slots are typically located on the bottom of the motherboard and are black or white. They are also longer than other types of expansion slots.
