Motherboards with PCI slots

PCI slot(s)

— the presence on the motherboard of one or more slots of the PCI standard.

Note that this interface should not be confused with PCI-Express. The PCI bus is the predecessor of PCIe; it is also intended for connecting internal peripherals, however, it has much more modest characteristics and is now considered completely obsolete. Therefore, slots of this standard are rarely found in modern "motherboards", usually in an amount of less than 1 – 2 pcs — based on some outdated and specific expansion cards that do not require high speeds
