PCIE 3.0 X4 Interface to 2X USB 3.1 GEN2 10Gbps Ports Expansion Card,2X 10Gbps USB-C Ports
FebSmart FS-C2-Pro is a PCI Express 3.0 X4 interface to 2X 10Gbps USB 3.1 GEN2 Type C ports expansion card. It will provide 2X USB 3.1 GEN2 Type C 10Gbps ports on Desktop PCs for USB-C devices large data transfer and live data storage. It was built in FebSmart Self-Powered Technology, users no need to plug any additional power supply form PCs PSU, but each USB 3.1 GEN2 port get 5V/3A (5V/6A in total) max power supply. Allow all connected high-power consumption USB 3.1GEN2 devices get a superspeed 10Gbps (16Gbps in total) max speed. It is a cost-affective way add 2X 10Gbps USB-C ports on Desktop PCs, Working Stations, and MAC Pros for high power consumption USB 3.1 GEN2 Type C peripheral devices connection, which including NVME SSD enclosures, SATA SSD/HDD enclosures, VR-Systems, 10Gbps USB hubs and 4K USB-C video adapter. The 2X added on 10Gbps USB-C ports will not occupy mother board USB Main Lan speed, just an extra bandwidth by PCI Express X4 on Desktop PCs.
What is the FebSmart Self-Powered Technology?
FebSmart Self-Powered Technology is a new solution to add more power supply on USB 3.1 GEN2 expansion cards. The old version PCI Express USB card need to plug a power cable from the desktop PCs power supply unit. Even added-on additional power, USB ports still lack power when running few high power-consuming devices simultaneously, such as USB MVME SSD enclosures. PCI Express slot can provide 75W max power almost 12V/6.25A. FebSmart add on 2X voltage transformer on 2X USB USB 3.1 GEN2 port, and pick up 12/2.5A transfer to 5V/6A 30W. Then distribute current to each port 5V/3A max power for USB 3.1 GEN2 devices. To protect users USB 3.1 GEN2 devices, FebSmart designed 2X electric safty fuse, 2X voltage stable capacitance and 2X voltage stable inductance. Do not worry data loss or burn USB devices now. Add superspeed plus 10Gbps USB 3.1 GEN2 host controller card on Desktop PCs. Choose More Stable, Fast and Safe data connection with FebSmart.

Achieving 10 Gbps Data Rates in USB 3.1 GEN2 Using Multiple INs and Hub Payload Buffering
What is USB 3.1 GEN2 Multiple-INs?
Now USB 3.1 can handle multiple device data transfer simultaneously, without waiting the first device accomplish it's task, NOT like USB3.0/2.0 does. USB 3.1 device may receive a second ACK TP for a different endpoint before it has a chance to respond to the first ACK TP. A more complex USB 3.1 device would take advantage of the multiple INs by servicing the requests separately, possibly returning data to each one, reducing the likelihood that Not Ready would need to be used.
How is Multiple-INs improving USB bandwidth?
When USB 3.0 Host Controller works with the external USB HUB is a “cut-through” model, upstream port and downstream ports on the hub were all operating at the same speed. When put in one USB 2.0 Hub all speed will down. Then USB 3.0 Host Cotroller can not run full speed. When USB 3.1 GEN2 Host Controller works with USB 3.1, 3.0 Hubs "Cut-through" will not work, with the new "store and forward” service, USB 3.1 hubs take a much more active role in making sure that the flow of data is smooth and the user’s experienced performance is not interrupted.

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 purchased an Oculus Quest 2 and found that I didn’t have a USB-C connection on my PC. I looked at various options, but settled upon this card. Wow. Talk about fast install into my PCIE-16 slot and quick driver recognition! I literally turned on the PC after install, and it found the drivers immediately. I use the Oculus Link (Oculus USB-C cord) and it works like a charm. Highly recommend this product!

UPDATE: after getting a second card and USB hub I ran into read errors. Even hooked straight to the card with a USB Samsung t5 drive I got random read errors. Attached it's one photo showing the readout in Linux and the next showing a successful run with the onboard USB. AVOID THIS CARD!Fast card and 5gbps devices actually ran at the full possible 625MBps compared to 450ish with a 3.0 controller. USB-c to a adapters will not work so if you have USB-a devices you will need a usb-c hub that has usb-a ports on it. Knocked a star as the half height adapter didn't fit right in my system. Tested though before returning.

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.

I just needed an extra PCI slot on my X570 motherboard and it was plug and play. The instructions stated that it was best to use an 8x slot. I was worried about blocking fans and used a 4x port. It works fine for the USB-C devices I'm using.

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.

Remove side cover, loosen PCI-e securing plate, plug in FebSmart USB 3 PCI-e card, reinstall securing plate and side cover, turn on computer and boot into either MacOs or Windows and enjoy USB 3 speeds for file transfers.It’s that easy!

I wasn't quite sure how to rate this. The product installs easily and both USB ports work. However, the port on the left (facing the rear computer) has good, consistent performance but the port on the right has poor, inconsistent performance. (I am keeping the product because I only need one good port.) To illustrate this point, I ran a disk performance program and attached the results. (Remember that the USB on the right varies dramatically in performance from run to run but is always much poorer in performance than the USB on the left.) You might want to keep this in mind, if you need two high performance USB ports.
