PCIe is the interface used to connect high-speed components. Desktop PC motherboards have many PCIe slots to add graphics cards, various peripheral cards, wireless LAN cards or solid-state drives, etc. The type of PCIe slots available in your PC will depend on the motherboard you purchase.

PCIe slots come in different physical configurations: x1, x4, x8, x16, and x32. The number after the x tells you how many lanes the PCIe slot has (how data is transferred to and from the PCIe card). x8 PCIe slots have eight lanes and can move data at a rate of eight bits per cycle. x32 PCIe slots have eight lanes and can move data at a rate of thirty-two bits per cycle.PCI Express Connectors in a through-hole configuration for high-bandwidth workstation and server applications, PCI-E x1(36P); PCI-E x4(64P); PCI-E x8(98P); PCI-E x16(164P).we have PCIe 3.0(8GT/s)&PCIe 4.0(16GT/s)&PCIe 5.0(32 or 25GT/s) connector,we have Straight DIP;right angle DIP;Straddle type;vertical SMT Type.
