USB 3.0 (3.1 Gen 2) Internal IDC 20 Pin Motherboard Header to A-Key 20 Pin Female Header Active Converter for Type C Panel Mount Adapter


USB 3.1 Type E Extension Adapter


  • It is a converter to convert the available USB 3.0 header of a motherboard into a USB 3.1 header. Thus the USB 3.1 port of a housing can also be supplied with USB 3.1 without a suitable mainboard.
  • Even the most up-to-date motherboards with AMD AM4 or Intel 2066 sockets are not always equipped with a USB 3.1 header. So it is the perfect solution to use the USB 3.1 connectors with Type-C or Type-A.
  • The small converter is plugged into a USB 3.0 header that provides two USB 3.0 lanes. Thus, two data lines with 5 Gbps each are available, which are bundled into a USB 3.1 header with 10 Gbit / s. The converter thus provides a full-fledged USB 3.1 port.
  • Converter plug-in for the mainboard ; Fits into any USB 3.0 header ; Convenient accessory for case with USB 3.1 connector ; Bundling in USB 3.1 with up to 10 GBit / s . The compact adapter can be inserted directly and requires no additional attachments.

USB 3.1 Front Panel Socket to USB 3.0 20Pin Header Male Extension Adapter for Motherboard ,This compact adapter adds one USB 3.1 Type-C internal 20-pin connector to your PC's existing motherboard by converting an unused 19-pin Type-A motherboard header to the newer standard. This allows PC owners to take advantage of new high-end PC cases that feature an external USB 3.1/3.2 Type-C port. Here are some of the CP14's key features:


Easy to Install


  1. Match up triangular arrows on the 20-pin 3.1 A-key female socket of the adapter card and the male interface of the cable extension mount and insert.
  2. Line up the socket key and insert the USB 3.0 IDC female side of the adapter into the male 20-pin USB 3.0 IDC motherboard header (be careful not to bend the header pins).


 Customer Feedback

1.This is the adapter you need for new cases and older motherboards.

 The description's not very clear here.

This adapter accepts the new "USB-C 3.2 front panel" connector, and converts it to the old USB 3.0 header style. This is useful for using an older motherboard (or one without a USB 3.2 header) in a newer case, such as a Fractal Define R6.

It appears to be a similar design to the Lian-Li PW-INC1TR, with the distinct advantage that you can actually buy it.

2.Brilliant Design & Function

 I NEED this for motherboards that don't have the new USB 3.2 (Gen 2) 20-pin, A-Key connector - which is the female end pictured in the description. *Matched with front panel Type-C connector on 5.25 slot panel*
>Design - (5 stars) for innovation and function; running full speed from ASUS Mark 2 X299 board - connected to a Samsung T5 portable drive. Nice upgrade for future USB Type-C. Low profile design fits perfect - better than the ole bulky cable that it replaced - no interference.
>Function - (5 Stars) I'm getting max speeds from this connector (dependent on Motherboard design). My board will get up to 5Gbp on the front panel which is 625 MB/s max - plenty for a portable drive (IMO)
>Price & Availability - (5 Stars) when they're in stock. Note the manufacturer - you will sell out of these faster than Amazon can refresh this page...

3.Get That extra USB Type C 10 Mbps Port On Your Maximus IX Hero mobo

This is the perfect cable to add an additional USB Type C 3.1 Gen2 port to my ASUS Maximus IX Hero motherboard. The cable plugs in perfectly with the USB3.1_E1 connector on the motherboard. I tested it with my USB-C 3.1 gen2/SATA dock and a SATA drive and it delivered the maximum transfer rate.
Workmanship on the cable was top notch.
My only request would be to place the Type C connector on a front panel plate.

4.Essential for adding front-panel USB-C support when your motherboard lacks the connector!

I recently built two new Windows 10 systems with MSI MPG Gaming Edge motherboards. While the motherboards do offer front-panel support for USB 3.2, the connectors on the board are only USB Type-A. This poses a problem if you buy a case with USB Type-C front-panel support, like our Phanteks P600S cases. To connect the USB-C front panel connector cable to the motherboard in this scenario, you need to use a motherboard adapter, like this one from Silverstone. It plugs into the USB 3.1 or 3.2 Type-A connector on the motherboard, so that you can then connect the USB Type-C cable coming front the front of the case to the motherboard. This gives you working front-panel USB-C on the case, even though the motherboard doesn't offer direct support.

I found installing this adapter to be a bit of a chore. The adapter changes the angle at which the front-panel cable connects to the motherboard, which may create some cabling challenges, depending on your case, front panel cables and whether the length of your graphics card requires that the cable run behind it. The adapter also fits very snugly into the USB Type-A connector on the motherboard, so it must be installed onto the motherboard first. You can't just install the cable into the adapter and then pop into place on the board. At least, it didn't work for me with my setup.
