Mini ITX PCI Express Port Multiplier — PCIe 1 to 4 (PCI Express 1X) External 4 PCI-e Slot Adapter ASM1184e

This Mini ITX-compatible adapter converts a single PCI Express 1X slot into four external PCI-e slots using the ASM1184e port multiplier. Designed to expand a PCIe 1 to 4 configuration, the card enables multiple add-on cards to be connected from one motherboard slot. Ideal for small-form-factor builds where additional external PCI-e connectivity is needed, the adapter presents four external PCI-e slots while retaining the original PCI Express 1X interface and ASM1184e controller.
