Vszerda PCIe 1x to USB 3.1 20-pin front panel adapter VL805

SKU CH-ZP81-HDN5K

Adds a USB 3.1 front-panel header to any motherboard via a PCIe 1x slot, using the VL805 controller for 5 Gbit/s speeds

  • Adds a USB 3.1 front-panel header via PCIe 1x slot
  • Delivers 5 Gbit/s bandwidth through VL805 controller
  • Converts a USB 3.0 20-pin header to USB 3.1 20-pin
  • Enables Type-C or Type-A front-panel ports on any board
  • Compact plug-in design needs no extra cables or brackets

PCIe 1x to USB 3.1 front panel adapter

This Vszerda adapter converts a spare PCIe 1x slot into a USB 3.1 20-pin front panel header. It targets PC builders whose motherboard lacks a native USB 3.1 header but who want to use a case with a front USB-C or USB-A port. The card uses a VL805 controller and fits any standard USB 3.0 20-pin header on the board.

Adds a single USB 3.1 header for front-panel use

The bundled hardware provides one USB 3.1 20-pin header that connects directly to the case front panel. No extra cables, brackets or driver discs are included; the adapter relies on the operating system's built-in USB 3.1 support. This lets you enable a front USB-C or USB-A port without replacing the motherboard.

Limited to 5 Gbit/s over a PCIe 1x link

The interface runs at up to 5 Gbit/s, which is the ceiling of the USB 3.1 Gen 1 specification used here. Because the card occupies a single PCIe 1x slot, total bandwidth cannot exceed what that link provides. It does not support higher USB 3.1 Gen 2 speeds, nor does it add multiple independent ports.

Questions about this item

Will the VL805 controller or the 20-pin header need replacement after extended use?

The VL805 controller is a solid-state bridge with no moving parts, and the 20-pin headers are rated for standard insertion cycles; neither component has a scheduled replacement interval.

What limits sustained 5 Gbit/s throughput on this PCIe 1x adapter?

The single PCIe 1x lane caps total bandwidth at 5 Gbit/s, so continuous transfers at that rate will saturate the bus before the USB 3.1 header becomes the bottleneck.

How much heat does the card produce when the front-panel USB 3.1 port runs all day?

The VL805 draws minimal power from the PCIe slot, so the adapter stays cool during all-day operation with no active cooling required.
