Vszerda N23985 PCIe 1x to 4-slot riser card

PCIe 1x to four-slot riser

The Vszerda N23985 adapter converts a single PCI Express 1x slot into four external PCIe connectors. It targets builders who need to attach multiple expansion cards to a motherboard with limited slot availability. The card plugs directly into the board and includes an integrated IC heat radiator. No auxiliary power cable is required for the PCIe slot itself.

Bandwidth limited to one lane

All four connectors share the single 1x upstream link, so total throughput cannot exceed one lane of PCI Express bandwidth. Each attached device negotiates at 1x speed regardless of its physical connector size. The USB 3.0 label on the external ports describes the cable interface, not the electrical lane count. Performance scales with the host platform's PCIe generation.

Four physical PCIe connectors

The adapter provides four slots for add-in cards such as network interfaces or capture devices. It supports DOS, Linux and Windows XP through 10 without plug-and-play enumeration. Builders who need independent bandwidth per card or hot-plug capability should choose a different topology.
