PCIe x1 to 4 PCIe x1 Slots Riser Card, Mini ITX External 4-Port PCIe Port Multiplier Adapter

Overview

Specs

Reviews

This PCIe port multiplier riser card turns a single PCIe x1 slot on your mainboard into four usable PCIe x1 slots, effectively resolving the shortage of expansion ports for Mini ITX small form factor PCs. The external structural design prevents space crowding inside tiny computer cases, allowing you to install multiple peripherals like network cards, capture cards, and controller cards at the same time. Optimized PCB wiring minimizes signal attenuation and crosstalk to maintain stable data transmission under multi-card load. Fully compatible with all standard PCIe slots from x1 to x16, this adapter requires no complicated driver setup.

It is an ideal expansion solution for mini workstations, industrial control equipment, home media servers and DIY Mini ITX builds.
