FOR aad in card PCIe 1 to 4 Riser Card — PCI-E 1X to External 4 PCI-e Slot Adapter / PCIe Port Multiplier Card for PCI express 16X slots

The FOR aad in card PCIe 1 to 4 riser provides a simple way to expand one motherboard slot into four external PCI-e connections. As a PCI-E 1X to External 4 PCI-e slot Adapter, this board lets a single PCI-E 1X interface host devices that fit PCI express 16X slots. Marketed as a PCIe Port Multiplier Card, it’s designed to add four 16X-capable PCI-e slots without replacing the motherboard. The compact riser format makes it useful for multi-card setups such as GPU arrays, expansion test benches, or other applications that require extra PCI-e connectivity. Use this adapter when you need to multiply available PCIe ports from one PCI-E 1X slot into four external PCI-express 16X slots quickly and efficiently.
