RAYSUN Dual 2 Port USB 3.0 A Type Female to 20 Pin Box Header Female Slot Adapter Cable for USB Ports Directly to Computer Motherboard

I have a slimline HP computer, so I was limited in how I could add USB 3.0 ports to this PC. I added a  Inateck PCI-E to USB 3.0 2-Port PCI Express Card with Internal USB 3.0 20-PIN Connector , but the small format case would only accommodate a low-profile PC slot cover plate, which provided only two of the possible 4 USB 3.0 ports. The Raysun Dual Port USB 3.0 adapter allowed me to use the other two ports on the card, accessed via a 20-pin USB 3.0 hub connector. It allowed me to connect two  Cable Matters 2 Pack, SuperSpeed USB 3.0 Type A to Micro-B Cable in Black 3 Feet  to the female USB 3.0 adapter ends, then run these out of a small opening in the back of the case (secured in place with cable ties), to provide two USB 3.0 flying lead connectors that reach to the front of my PC. I can connect my external USB 3.0 hard drives via these cables, keeping the two USB 3.0 ports on the PC back panel free for other uses.The Raysun Dual Port USB 3.0 adapter that I received is well-made and appears to be high quality. Both the 20-pin USB 3.0 hub connector and the two female USB 3.0 sockets are neatly molded, with good-quality cables providing a robust connection between the two ends. It measures around 10.5 inches from end to end (including the adapter ends). This meant that it would - just - reach from the 20-pin USB connector at the back of the PCI Express card to the front of my 16" deep PC case (if I had bought it for that purpose). If I had a typical mini-tower case, this adapter would probably have needed an extension cable to reach to the front panel.When I tested the performance of the USB 3.0 connections via the adapter, using CrystalDiskMark 3.0.3 x64 under Windows 7, they were easily as good or better than the two back-panel USB 3.0 ports provided by the PCI Express card directly. I was achieving 70-80 MB/S USB3.0 Sequential Read, 1000MB, and 60-75 MB/s USB3.0 Sequential Write, 1000MB - even with 40% disk occupancy on both drives. So I am a happy bunny and confident that this adapter does its job well!

Somehow managed to short out my previous cord. I stripped part of the casing off the input socket to fit snuggly into computer. Worked great as a replacement.

I am using this with  ASUS PRIME X299-DELUXE LGA2066 DDR4 M.2 U.2 THUNDERBOLT 3 USB 3.1 X299 ATX Motherboard with Dual Gigabit LAN and 802.11AD WIFI for Intel Core X-Series Processors This is the only cable that allows me to connect the USB plugs on the motherboard to my PC case.

Not much to say when the product works like it should.Connected to the header on my motherboard for dedicated Keyboard and Mouse ports.Have had 0 issues and no complaints on the price.

it works and is simple to install but does not supply the magic that I require for 5 stars

Upgraded my HAF X front ports to USB 3.0 that wasn't available when that case was manufactured. Would buy again.
