FebSmart 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)

Extra USB Ports Without the Hassle I installed this FebSmart PCIe 4-port USB 3.0 expansion card on a mid-tower Windows 10 desktop that was running low on available ports, and it worked right out of the box. Windows recognized the card instantly without needing extra drivers, and I appreciated that it doesn’t require a separate power connection. The self-powered design is a big plus because I didn’t have to mess with extra cables or worry about overloading the PSU. Performance is as expected for USB 3.0—transfer speeds are solid and stable, and all four ports can be used simultaneously without slowdown. I tested with external SSDs, flash drives, and even a USB headset, and everything connected seamlessly. The card sits securely in the PCIe slot and feels well-built, with no loose or flimsy components. One thing to note is that while this card does fine with most devices, really power-hungry peripherals (like certain external hard drives) may still prefer a powered hub for guaranteed stability. Also, keep in mind it occupies a PCIe slot, so plan accordingly if you’re short on expansion room. Bottom line: A reliable and hassle-free way to add fast USB 3.0 connectivity to an older or port-limited desktop PC, with the added convenience of not needing an extra power supply connection.

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).

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).

The item arrived as described in a well packaged box. Installation went fine and Windows 10 immediately recognized the chipset and downloaded the latest Microsoft approved drivers. I have 3 devices, all USB 3, attached to this board. I/O to and from the devices connected to this board, to other devices NOT connected to this board is very fast >200mb/sec. However, any transfers between devices connected to this board slows down to USB 2 speeds around 55mb/sec. Not sure why this is happening. I will contact tech support after more testing.

Very good product at a decent price.

Inserted the new 4 port USB in my Dell 7010 business desktop CPU and it worked instantly with 4 USB devices ported. Product power supply failed on two ports just out of guarantee. Bad product as far as 5V power port/s

The card operated well for slightly less than 5 months then abruptly failed. Good performance but very disappointed with the reliability.

Works great, looks nice. Placed in a desktop system that needed some upgrades and it works well. I am glad they included the small and big size outer cover that goes onto the back of the computer. I needed the smaller one for sure and I was happy to see the smaller one in the box. Product did not come in a messed up box so that is a big plus. Easy to install and for the price that I bought it with, it was worth it. Now my mom can enjoy a nicely renovated desktop system that has USB 3.0 slots for maximum speed in her USB's that she uses.
