PCIE X4 to 2X 10Gbps Max Speed USB 3.1 GEN2 Type E Key A Ports Card, USB 3.1 GEN2 10Gbps Header for Desktop PCs Front Panel USB-C Ports, Built in Self-Powered Technology (FS-E2C-Pro)

Seems great. Easy to install. The directions were clear enough. At least with my computer, I didn't have to install any drivers - the computer just saw it. I've got it hooked up to a direct attach storage device and the performance seems good.

Solved my problem. I got a so-called Microsoft Modern Speaker, which is speaker microphone combo designed to work with Microsoft Teams (it works as a speaker/mic for anything, not just teams), but it is USB-C. I got cheapo USB-C to A converters, but the audio was unreliable. The Modern Speaker worked on my Mac with native Thunderbolt/USB-C, so I decided to try this card. It works like a charm. Now the Modern Speaker works as expected and now I can plug in my other, well, modern peripherals.I was a little concerned about buying some unknown brand that is designed and made in China (because it gets bus access to my PC and I don't trust rando devices to not contain spyware chips these days, not because of xenophobia), but I had a peak at their website, which had some pretty humorous and humanizing content on it, so I decided as long as it worked with the Microsoft-signed drivers, I'd use it. It's not a 100% guarantee, but they seemed far more legit than most of the no-name stuff on Amazon.

Only get this card if you’re OK with 5Gbps and no charge capability. It’s easy to think something works when you don’t know what to look for. For the most part, it appears to work and installation is a breeze with plug & play; however, when I tested the ports on 2 very high end machines they both only got transfer speeds of just below 5Gbps, not 10Gbps as advertised. I just don’t know how it can be legal for companies to not just be misleading but out right lie to sell a product, especially when the majority of people don’t have the equipment or knowledge even to test the product. Since I found so many reviews saying the same thing, 1 star for misleading the ignorant and straight up false advertising.

I'm using an old X99 era motherboard, so didn't have USB-C access (for data & power) and I recently bought a sound bar and a USB hub (with 3.0 jacks but powered by USB-C). I was really worried an cheap random brand might cause some kind of electrical issue and burn out my motherboard (which I don't want to lose). But it's been working flawlessly powering the sound bar (Creative GS3) and multiple USB devices.

I recently built a workstation using an older Supermicro server motherboard inside of a Fractal Meshify case which had multiple USB ports on the front. As the Supermicro was intended to be a server board, USB headers were limited a single USB 2.1. As I wanted to leverage the high speed USB-C ports on the Fractal case, as well as the other USB-A and USB-C ports, I purchased this card and am pleased to report it does just what I needed. I had to buy another adapter to use the USB 2.1 header on the USB 3.1 header port but I expected that already. The only thing I would say is be careful trying to do multiple high speed transfers at the same time as it seems to be easy enough to max out the PCIe x4 bandwidth and if you have wireless keyboard or other input devices in the same ports alongside the storage device you're transferring from, you can definitely count on the peripherals suffering and lagging.

I bought this card for a custom build (Aorus X399 Gaming 7, Threadripper 1950X, 128GB RAM) I inherited because I wanted more than a single USB-C 3.1 Gen 2 (10Gbps or 1.25GB/s). I knew the combined speed states the card can handle a combined transfer speed of 16Gbps (2.0GB/s) so to see a stable 1.71GB/s wasn’t surprising. I figured the card was utilizing all of its total available bandwidth.As surprised as I was at that I was even more surprised when it burst saturated at 4.04GB/s (32.32Gbps). The external device is a random USB4 enclosure with a WD Black SN750 NVME drive. The internal drive is a Samsung 980 Pro. Somehow this card was able to transfer and entirely saturate 4 PCIE lanes with data.This could be a fluke but so far this has been a consistent experience for me.

Speeds are fast but the power delivered through the cables is quite low. Intended to use this for oculus quest on PC but the ports couldn’t provide enough juice for sustained gaming.

I am happy. Windows 11 picked it up instantly and I now have USB3.1 second gen on my front header. It has been tested an meets with my approval. The card has two connections (not that I anticipate needing the second) but I can imagine how someone might.
