  • Good product
  • Worked well, the included driver doesn't support Windows 10 as would be expected, so if you purchase download the one from there website.

  • 0 ports on the front of my PC and works great.
  • Hooked it up to the Anker product that has to USB 3.0 ports on the front of my PC and works great.
  • 2015-10-02

  • Upgrade to high speed USB ports
  • Great way to add 4 USB 3.0 high speed ports. Works well so far.
  • 2015-10-01

  • Installed easily on a windows 10 machine
  • Installed easily on a windows 10 machine. Included drivers worked. It is helpful that it has the internal 20pin USB 3.0 port that I could connect to a built in front USB 3.0 port on my case. Very satisfied.

  • like a moron
  • I use Win7 x64 because Windows 8 and Windows 10 are...well.....(expletive deleted). Windows 7 device manager showed a yellow explanation mark and I had tossed the CD, because, like a moron, I figured Windows Update would locate a driver. It didn't. Fortunately, I went to Ankers site (I love Anker products) and the driver was right there. Here is the link if it helps anyone. can't get my USB keyboard to work in legacy mode but a keyboard doesn't need USB 3.0 anyway. I'm sure this just a BIOS setting, likely I have legacy USB 3.0 support disabled in the BIOS.Lastly, the front panel header cable for the USB 3.0 slots I have on my case is really flaky. This is NOT the problem with the card - it's my CoolerMaster case. The header cable does not securely grab the pins. Once I had the header cable working properly, I used a little electrical tape to hold the cable in place. That was actually the reason I bought this card - I busted the motherboard pins for the front panel USB header cable because the cable is crap.Anyway, bottom line....installed the card in a proper PCI-E slot, installed the drivers that I downloaded from Anker and life is good again.

Customer FAQ

Q1.  The device connected via the PCI-E card keeps disconnecting from the computer or restarting while transferring data. Why is this?
This is probably being caused by insufficient power supply. The PCI-E interface provides some power, but the main source is the 4-pin DC connector. Ensure the 4-pin connector has been securely inserted into its socket on the motherboard.
Q2.  Why am I receiving a “Code 10” error?
"In simple words, a Code 10 error is a very generic message indicating some kind of unspecified driver or hardware problem. Please try the chipset maker's newest driver, which you can download at: For more troubleshooting tips, you are welcome to have a look at this page:"
Q3.  I’m getting a driver conflict/error/failure message. What should I do? Where can i get the updated driver?
In addition to installing the driver on the CD you can also download it via our website. You can even download the chipset maker's newest driver from:
Q4.  Which types of computer frames are compatible with the PCI-E card?
The PCI-E card is compatible with all standard computer frames. For Mini frames, the Low Profile Bracket is needed to insert the card into the computer’s internal PCI-E port. Please note that the Low Profile Bracket is not included.
Q5.  What are the different interface types for PCI-E cards?
The interface types for PCI-E cards include: PCI-E X1/X2/X4/X8/X16. The most prevalent types are PCI-E X1 and X16, which are supported by our products. Remember to only connect to PCI-E slots when the computer is powered off.
Q6.  How do I install the PCI-E card?
There are 3 steps needed to install the PCI-E card:
    a. Be sure your computer has been powered off, then open the computer case.
    b. Insert the PCI-E card firmly into one of the available PCI-E X1 / X16 interfaces, then connect the 4-pin DC power cable to its corresponding connector on the motherboard.
    c. Turn on the computer and install the driver.
Q7.  Why is the transfer rate so much slower than the 5Gbps promoted?
The USB 3.0 transfer rate is 5Gbps and has a theoretical transfer speed of 500MB/s which is about 8 times faster than the USB 2.0 transfer rate of 480Mb/s with theoretical transfer speed of 60MB/s There are numerous variables that will affect USB transfer rate including data source and destination and file type. With all reasonable usage environments taken into account USB 3.0 can achieve average transfer speeds about 3 times faster than that of USB 2.0.
Q8.  What is the USB 3.0 20-pin interface?
The 20-pin interface is the standard USB 3.0 pin interface, usually located on the computer’s motherboard. This 20-pin interface can be converted into 2 USB 3.0 female ports via the USB 3.0 adapter cable.

Does not work with Windows 10

How soon can you release a driver for Windows 10?  This should have been anticipated before the official release of Windows 10.  I can't find a reason why Anker wasn't able to get a Windows 10 beta to start working on a compatible driver.

We are very sorry for all the trouble that this might have caused. Unfortunately, we do not receive a pre-version of a system before it is being released. Windows will have done some last minute changes as well.

We are currently testing our products with Win 10 and will be finishing our tests this week. If you are experiencing a specific problem, please contact our friendly service team and they will try to find a solution for you:

Again, apologies for this incident.

Give them time. The technical, developer, test, etc... editions have all been changing up to the very last day. So in some cases being "prepared" wasn't an option.

What I wanted to know was, which two pins on the 4 pin socket take the plus and minus 5Vs.

if you are using with your desktop you can use 5 port from the power supply or 20 port to use with the USB PCI Express card

If you mean the male molex connection the 2 center pins are ground connections while the right pin is a 5v positive and the left pin is a 12v positive.

Hello team. I have just fitted a USB 3 E card. Because my Acer EL1850 PC is fairly new, I presumed it would have a 5V 4 pin plug to spare. Silly me!

I do have an external 5V DC power source I'd like to connect. Would you please give me the 4 pin details of the 4 pin socket on the card so I can plug in correctly.

there is 20 pin and 4 pin in power supply if you have power supply with 20 pin or 4 pin connector use those

You will need a normal peripheral 4 pin power connector for PC.

Front panel card reader

I have a Lian Li card reader CR-26U3 which plugs into the 20pin port of this unit. The USB port on the reader works fine but none of the SD or MS slots come alive when I insert a memory card.

Lian Li told me their device doesn't need any specific drivers and I have updated my Anker PCI-E device drivers to 4.90 from this web site.

Anker sells though their storefront at Amazon and also through their storefront at eBay. You may find that because of the way Amazon operates that some products have wider distribution worldwide at the eBay store.
