PCIe slots are a key component of modern motherboards, as they allow for multiple expansion cards to be installed. A motherboard with PCIe slots will typically have at least one, but some models may have as many as eight or more.
The number of PCIe slots on a motherboard is important to consider when choosing an expansion card, as the more slots there are, the more options you have for choosing the right card. Additionally, if you plan on installing a lot of expansion cards, it is important to choose a motherboard with plenty of PCIe slots so that everything can fit without crowding.
