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)

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!

Easy installation and setup.

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).

Being vertical, these USB ports have some problems with the computer chassis because they collide against the metal of the chassis atx and you have to break the metal of the chassis so that the cable ports that you are going to connect can fit.

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).

Did NOT work on my PC with current version (24H2) Windows 11. Tried card in all four available PCIe slots, to no avail. Will be ordering a different brand that uses a different driver.

I used this to connect my backup drive to my old computer. It was exactly what I needed. Works great.

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.
