We do not currently sell any USB 3.1 Type-C cards that use a Renesas chipset. Nick, StarTech.com Support **Q: Does this work on pcie 2.0 x16 slot supporing max x2 speed ?** A: It's pcie x4 so putting it in a x16 slot will work, it will scale down. You just can't put it in one that is a x1 slot, it has to be x4 or higher. **Q: Lets say I run one device on a given channel, does that device have the full 10Gbps bandwidth or is it limited to 5?** A: The PEXUSB314A2V has two dedicated channels split to two ports each. If you plug in a single device on one of the channels it should get the full 10Gbps.

PCI-e 4x provides good read-write speed considering the board is PCI-3 Gen 2. Not quite the speeds of native USB 3. I'm certain it would be much faster with PCI-e Gen 3 board, but a definite improvement on an older motherboard.An important feature for me was that it allowed me to utilize the front panel USB 3.1 ports on my case. The front panel cables / plug fit right in on the card without a hitch. Installation is a snap.The card will install in an 8X or 4X slot.The type C connector on the back is a nice touch. For me it was all about being able to use my front panel ports. That kind of stuff drives me crazy. It's a good value with all the features you want. I think it's one of the better cards out there.Windows 10 picked it up on reboot and loaded the appropriate drivers. No issues at all. ### ⭐⭐⭐⭐⭐ Works with PCI-e version 2.0 hosts. *by A***. on January 12, 2020* I installed into a Dell Optiplex 990 running Win7 32 bit. The Dell had a free PCI-e 4x slot, which this peripheral requires. This model of Optiplex has PCI-e V2.0 on the motherboard, which can get you 5GB performance on each port.As others have noted, the "ASMEDIA" designation emblazoned right on the processing chip is very difficult to read, but I got a magnifying glass, confirmed it, and so just went ahead and downloaded the Win7 installer package offered at the StarTech website. Didn't use the CD at all.Note that the downloaded ASMEDIA driver from the StarTech website will not run SETUP without the hardware being detected. You may be used to installing software drivers before you install corresponding hardware, but that's not the case here.My model: PEXUSB312A2So far, so good, but today's my first day with it. It seems to have solved the problem I specifically bought it to solve: sluggish USB 2.0 being the bottleneck on my Samsung FIT 128GB USB 3.1 device, which I was trying to use as the hard disk cache location for my web browser.I'm getting great read speeds now. Writes, not so much, but that seems to be a problem with the Samsung. I may yet graduate to an all-around speedier device, to get the most out of my $35 investment in the card. I just went ahead and applied (optional) SATA power up front, because if it does turn out to be necessary, crawling under the desk and getting that all done is just too much trouble.Beware of "bulky" USB devices which physically spread out. Although the spacing of the two ports looks pretty reasonable on this StarTech card, I could not fit a Samsung FIT and a Corsair Voyager GTX (256GB) at the same time.(The Voyager is a fat little device.) ### ⭐⭐⭐⭐ Works best when correct Drivers installed. *by M***N on February 5, 2019* I purchased this item as a way to future proof my PC and expand the USB Ports. I had a USB TYPE C Gen 2 dock that was designed for 10gbs to connect to this item. Installation of this card was easy and I installed the ASMedia Drivers from the StarTech website as instructed. The card showed up in the device manager and everything seemed to be ok. However when I did a CrystalDisk check, the results were not what I expected. I could not get more than 300mbs read/write out of a 512gb SSD installed in the dock. I have a trick up my sleeve to find out what is wrong. I have another PC that has a Windows Mixed Reality Headset installed on it. There is a test that you download from Microsoft that will check everything on your PC needed to run WMR, including the usb ports. I ran the test and sure enough the test said there was a issue with ASMedia drivers and the solution was to replace them with Microsoft Drivers. I did that and ran the CrystalDisk scan and it nearly doubled to 550 mbs. I ran the WMR test again and it checked good. If you want to find out on how to do this,run the WMR test and follow the instructions on what to do when it shows USB port failures. All I can say is that after I did this everything is working as it should and I have not had any issues since. ## Frequently Bought Together - StarTech.com 2 Port USB 3.1 (10Gbps) Card - USB-A 1x External 1x Internal - PCIe USB 3.1 Card with Type-A - PCI Express (PEXUSB311EI) - StarTech.com Shielded External eSATA Cable - eSATA cable - Serial ATA 150 - eSATA (M) to eSATA (M) (3 ft) - black (ESATA3) - Cable Matters 2-Pack 6 Gbps Shielded eSATA Cable 6 Feet --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/31721688-startech-com-2-port-usb-3-1-10gbps-card-usb](https://www.desertcart.sg/products/31721688-startech-com-2-port-usb-3-1-10gbps-card-usb) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-05-25*
