Green PCIe x1 adapter card with 19 and 20 pin headers and 4 pin power connector

Vszerda

Vszerda PCIe x1 to 19/20 Pin Adapter NEC720200 network card

SKU CH-PQPA-6S2YD

Adds two internal USB 3.0 headers to a PCIe x1 slot using a NEC 720200 controller and IDE power

  • PCIe x1 slot converts to 19 or 20 pin internal header
  • NEC 720200 chipset drives the external-to-internal adapter function
  • IDE 4-pin power connector supplies onboard voltage
  • Expansion card installs in any standard PCIe x1 slot

Vszerda PCIe x1 adapter card

This Vszerda adapter converts a PCI Express x1 slot into 19-pin or 20-pin internal headers with an IDE 4-pin power connector. It uses the NEC720200 chipset to bridge the external PCIe interface to internal connectors. The card suits builders adding front-panel USB ports or similar headers to a desktop system.

Practical limits of PCIe x1 bandwidth

The single-lane PCIe link caps total throughput at the x1 electrical limit, so attached devices share that bandwidth. The IDE 4-pin power connector supplies auxiliary power but does not increase data rate. Buyers needing multi-lane speeds or additional power phases should choose a different expansion topology.

Questions about this item

Should I use the 19-pin or 20-pin header on this Vszerda adapter?

Match the pin count to your motherboard header; the card provides both 19-pin and 20-pin connectors so either can be used.

What does the NEC 720200 chipset do once the card is installed?

It bridges the PCIe x1 slot to the internal 19/20-pin headers, letting the board expose those ports through the expansion bus.
