Vszerda N23985 PCIe 1x to 4-slot riser card

SKU CH-AX98-Q640F

Connects four PCIe cards to one 1x slot using a single cable with an IC heatsink, no extra power required

  • FeaturesDesktop
  • Expands one PCIe slot into four without extra power cables
  • Compact 120 × 66 × 21 mm board plugs directly into the motherboard
  • IC heat radiator keeps the multiplier card cool under load
  • Single USB 3.0 cable simplifies installation and cable management
  • Runs on DOS, Linux and Windows XP through 10

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.

Questions about this item

How many expansion slots does the N23985 provide?

The card converts one PCIe 1x slot into four PCIe USB slots for additional devices.

What bandwidth does the single 1x uplink deliver to the four slots?

All four slots share the throughput of one PCIe 1x link, so total bandwidth is limited to that single lane.

Which physical interface does the adapter plug into on the motherboard?

It inserts directly into a standard PCIe 1x slot on the mainboard without an extender cable.
