FebSmart2X 10Gbps Max Speed USB-C Ports PCIE USB 3.1 GEN 2 Expansion Card for Windows, MAC OS and Linux PCs, Built in FebSmart Self-Powered Technology, No Need Additional Power Supply (FS-C2-Pro)

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!

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.

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.

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.
