Five black 15 cm adapter cables with 20-pin female and 9-pin male connectors

Vszerda

Vszerda USB 3.0 20-pin to USB 2.0 9-pin adapter cable 15cm 5pcs black

SKU CH-2SV5-30HXP

Five-pack of 15 cm black adapter cables connecting a motherboard USB 3.0 20-pin header to a USB 2.0 9-pin plug at 480 Mbps

  • Connect USB 3.0 headers to USB 2.0 ports with 20-pin to 9-pin conversion
  • Five cables included for multiple internal device connections
  • 15 cm length fits tight case routing easily
  • Double-shielded twisted-pair wiring reduces crosstalk for stable 480 Mbps transfer
  • PVC jacket provides durable, flexible protection for daily builds

Five-piece USB 3.0-to-2.0 header adapter set

This five-piece set converts a motherboard USB 3.0 20-pin header into a USB 2.0 9-pin connection. Each 15 cm cable has a USB 3.0 19-pin female plug on one end and a USB 2.0 9-pin male housing on the other. It lets builders attach front-panel or internal USB 2.0 devices to newer headers. The pack suits system integrators and hobbyists who need multiple adapters for a single build.

Passive wiring with double-shielded pairs

The adapters contain no active circuitry, so they add no heat and draw no extra power beyond the attached device. Double-shielded, twisted-pair data lines reduce crosstalk to keep the link stable at 480 Mbps. PVC jackets stay flexible during routing and resist cracking inside tight cases. Operation is silent because there are no fans or moving parts.

Direct header-to-device connection

Each cable plugs straight into the motherboard’s 20-pin header and the device’s 9-pin socket without brackets or extra cables. The short 15 cm length keeps internal routing tidy and frees space behind drive cages or power-supply shrouds. Five identical units let you equip several front-panel ports or internal hubs at once. Buyers who need USB 3.0 speeds or longer internal runs will need a different solution.

Questions about this item

How do I install the 20-pin to 9-pin adapter cable and which step is often missed?

Align the 20-pin female connector with the motherboard USB 3.0 header, noting the keyed pin‑20 position, then press the 9-pin male end into the USB 2.0 header; the step often missed is matching the missing‑pin orientation on both headers before applying force.

What maintenance or replacement will the 15 cm PVC‑shielded cables need later?

The cables are passive with no moving parts; inspect the PVC jacket and double‑shielded twisted pairs periodically for cracking or kinking, and replace any unit that shows damaged insulation or bent pins to keep 480 Mbps throughput reliable.

What limit appears first under sustained use of the USB 3.0 to USB 2.0 adapter?

The USB 2.0 9‑pin header caps the data rate at 480 Mbps, so sustained transfers will hit that bandwidth ceiling long before the 15 cm cable length or PVC construction becomes a factor.
