PCIE 4-Ports Superspeed 5Gbps USB 3.0 Expansion Card for Windows 11, 10, 8.x, 7, Vista, XP Desktop PCs, Built in FebSmart Self-Powered Technology, No Need Additional Power Supply (FS-U4L-Pro)

I have a full size tower, but I really like that the FS-U4 can be used in a mini-tower PC. I am not using this for a power source; I have a powered USB hard drive attached. It installed flawlessly in the case, and Windows 10 recognized it at boot with no extra help. Data coming from a USB 2.0 hard drive via the mainboard port to the USB 3.0 hard drive is about 32MB/s (~320Mb/s) ... which is a lot faster than when the same USB 3.0 hard drive was connected to the USB 2.0 port. It can write about 131MB/s coming from the SATA C: hard drive to the USB 3.0 hard drive. The only complaint I could have, is that I wish it came with a 'Y-splitter' power cable. I have a 750W power supply, but the power connectors are limited.----------2019/03/20----------Bummer. Microsoft just upgraded me to Win 10 Version 10.0.18356 Build 18356 last week, and this is no longer working. I have uninstalled and re-installed vendor and Microsoft drivers, but cannot get to work any more. The USB xHCI Compliant Host Controller just shows a little yellow triangle in Device Manager, and the Reneasys driver only sticks around until reboot, then it gets replaced with the xHCI one. The explanation is very helpful: This device cannot start (Code 10).

Great picture, thanks, I know. The card being reviewed is the bottom card, and you can see blue light coming from the open two ports; the other two are in use. The card does not cause the blue light, but I grabbed some fancy CPU cooler to keep my CPU from melting. The card is small, plugged into an open PCI-E port, and comes with two back panel plates, one for a tighter chassis design and the other for a traditional full-sized case. It plugged in, and it just worked on my Windows 10 older AMD computer (like 10ish years old). I have used hard drives via the card's USB 3 and had no issues. While I doubt my system can push the card to the max, the motherboard only had 2 USB 3 ports, and I needed more. For the $20, this is a cheap upgrade.

Easy installation and setup.

If your case's PCI slot cutouts are slightly narrower than usual, you'll have a very hard time using this card. Apparently the Fractal Meshify C has slightly narrower PCI slot cutouts, and I can only fit USB connectors through them by inserting them at an angle and then twisting into place. Obviously, this is not good for the USB cables, and removing them once inserted is even harder.Once a USB cable is wrangled and shoved into the port, the card works great!I did not intend to return the product because it does technically work, but note that the product description states the seller won't accept returns once you open the packaging anyway unless it's defective. Make sure your case's PCI slot cutouts are wide enough to fit a USB connector through before you order.

Pleasantly surprised! I have a low profile budget office PC and needed usb 3.0 ports. This is a great solution the ports are snug because the area is super narrow, I mean super narrow.m, but now I have 4 great high speed ports!

Installed the card and downloaded the latest drivers for window 10. It ran fine when using 2 of the 4 usb ports. But if I use 3 or more they randomly drop the external harddrives I have attached. I have used those external harddrive on another pc no issues. But when just using 2 usb the speeds are excellent. So extremely disappointed that I can only use two of the 4 available since I need 4.

I'd read that W10 would detect the hardware and auto install the drivers for it. Not so in my case. I think it depends on how old your machine is and what hardware you have. My machine is a good 10 years old, but it has an early iteration of an i7, with added memory to at least give me 8GB there. But it did turn out to have a working PCIe card slot, and this fit perfectly. Not my main machine but a side project to see how I can keep it running at a fairly high level. A couple notes: it showed up in Device Manager as an unknown device, and not under USB controllers. I tried installing the drivers straight from W10 but no dice. So I installed the drivers from the little cd included with purchase. It required a restart after that before finally detecting the brand name under USB controllers in Device Manager. So...you might need to ignore the troubleshooting tips in the included pamphlet instructions like I did...as it called for reseating the card after failure to detect as intended. In the end: seat the PCIe on your motherboard, then install the drivers off the cd, then reboot, then check and make sure it took in Device Manager (if your system doesn't detect it right away and install drivers from DM).

This worked fine in a Win 10 PC for about three years and then just failed. So, three years is sufficient given its price. But having to pull it out is a pain. If I would make the decision again I would use a multi port dongle and plug it into one USB port on the mother board for use with low demand devices (keyboard, mouse, cam).
