Vszerda Dual USB 3.0 A Female to 20/19 Pin Header Adapter

SKU CH-21BT-64E5M

Adds two USB 3.0 Type-A ports to a motherboard 20/19-pin header at 5 Gbps

  • Connector DetailUSB Type A
  • Constructioncopper
  • Add two USB 3.0 ports via a 20/19 pin motherboard header
  • Supports 5 Gbps transfer speed for fast external drives
  • Backward compatible with USB 2.0 and 1.1 devices
  • Copper construction ensures reliable signal integrity
  • Horizontal PCBA design fits tight internal chassis spaces

Internal USB 3.0 expansion adapter

This Vszerda adapter converts a single motherboard 20 or 19 pin header into two external USB 3.0 Type A ports. It targets builders who need front-panel or bracket-mounted USB 3.0 connectivity without using rear I/O slots. The horizontal PCBA layout fits tight internal clearances. Backward compatibility with USB 2.0 and 1.1 devices is maintained.

Passive thermal and power profile

The adapter draws power directly from the motherboard header and adds no active cooling or fan noise. Copper construction handles the 5 Gbps signal path without extra heat under normal peripheral loads. No external power connector is required. Power consumption stays within the header's rated limits.

Plug-and-play connectivity

No drivers, firmware or bundled software are included; the device relies on the motherboard's native USB 3.0 controller. The two Type A ports accept flash drives, USB-LAN adapters or other peripherals immediately. Buyers who need internal USB-C ports or additional headers beyond the single 20/19 pin input will not be served by this adapter.

Questions about this item

How do I plug the 20-pin header into the motherboard USB 3.0 connector without bending pins?

Align the keyed 20-pin box header with the motherboard's USB 3.0 male header, press straight down until fully seated, then secure the bracket to the case so the two Type-A ports face outward.

Will the copper contacts need cleaning or replacement after repeated USB 3.0 device swaps?

The copper contacts are rated for standard mating cycles; occasional dry contact cleaner on the Type-A ports is enough if resistance appears.

What throughput ceiling appears first when two USB 3.0 drives transfer simultaneously?

The single 20-pin header carries one 5 Gbps USB 3.0 channel shared by both ports, so combined sustained throughput cannot exceed 5 Gbps.
