PCIe expansion slots are typically found on motherboards that are designed for high-end graphics and gaming systems. They offer extra connectivity options for add-in cards, storage devices, and other peripheral components.
A PCIe slot is a type of expansion card slot found on motherboards that support the PCIe bus. PCIe stands for Peripheral Component Interconnect Express and is a serial bus standard for attaching hardware devices to a computer.
PCIe slots typically offer more bandwidth and speed than traditional PCI slots. This means they can support faster graphics cards and storage devices.
The types of devices that can be installed in PCIe slots vary depending on the motherboard and model of graphics card you are using. Some common items that can be installed in PCIe slots include:
Graphic cards
Storage devices, such as hard drives and optical drives
Sound cards
Network adapters, such as Ethernet cards
USB 3.0 flash drives.
