PCIe 1 to 4 PCIe 1X Riser Card, Mini ITX PCI Express Port Multiplier Adapter Expand 1 PCIe X1 to 4 External PCI-e X1 Slots

This PCIe 1 to 4 PCIe x1 port multiplier riser card is a practical expansion accessory for Mini ITX and compact motherboards with limited built-in PCIe slots. It takes one available PCIe x1 slot on your mainboard and extends it to four independent external PCIe x1 interfaces, greatly expanding the expandability of your small host.

Adopting professional signal processing circuit design, this adapter effectively reduces signal attenuation and electromagnetic interference to ensure stable and continuous data transmission for all connected PCIe peripherals. It is widely compatible with most common PCIe x1 devices, including Ethernet network adapters, video capture cards, audio sound cards, PCIe USB expansion boards and industrial control modules.

The external slot layout avoids crowded wiring inside narrow Mini ITX chassis, making hardware installation, replacement and maintenance much more convenient. Perfect for mini workstations, industrial control PCs, home media servers and small DIY hosts that need multiple external PCIe expansion devices simultaneously.
