What is FebSmart Self-Powered Technology?
FebSmart Self-Powered Technology is a new solution to add more power supply on USB 3.0 expansion cards. The old version PCI Express USB 3.0 cards need to plug power cables from Desktop PC’s power supply unit. Even added on additional power, sometime it still lacks power when running few high power-consuming devices simultaneously such as USB HDD/SSD enclosures and USB NVME enclosures. PCI Express slot can provide 75W max power almost 12V/6.25A for PCIE devices. FebSmart add 4X voltage transformer on USB 3.0 card will pick up 12V/3.5A power and convert to 5V/8A 40W. Each USB 3.0 port will get 5V/2A 10W max power supply for USB 3.0 devices. Most of the high-power consumption devices just need 4~8W which means this USB 3.0 expansion card can light up 4X high power-consumption devices simultaneously. FebSmart built 4X electronic safty fuse, 4X voltage stable inductance and 4X voltage stable capacitors on the board, will protect users’ data and USB 3.0 devices. Never burn USB 3.0 device and never lost data. Add 4-Ports superspeed 5Gbps max USB 3.0 expansion card on Desktop PCs. Enjoy more stable, superspeed and safe USB 3.0 connection with FebSmart.

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

I ordered this product for my recording studio. Easy to install, it works just fine. I would recommend it to anyone.

I needed more USB connections for external devices on an older computer. This provided that and drivers installed without problems. I did run into an issue where many weeks later I received a USB error, making me a bit worried if this will last and/or is reliable for external drive usage, but no drive errors have occurred to date that i know of.

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.

This card would constantly fail to start in one older high end pc. I put it aside but I recently built a new high end audio/video workstation and decided to try this card again.After extensive testing, using a USB 3.1 samsung flash drive with over 20 GB of data on it and writing to a 2 TB NVME M.2 with over 1.8 TB of space and setting the card properties for best performance, I was getting up to 280 MB/Sec speeds. That was fantastic and close to the max specified speed of the flash drive itself. However, it would continually fail - never could move more than 16 GB of data without stopping and showing an 'Out of Memory' error. With 64 GB system memory and 60 of it available, seems like a driver or card issue.I did the same test with the 3.0 ports directly on the motherboard back plane, same flash drive and test and never had any issue with it completing.I then upped the the amount of data on flash drive and had the same results.Basically, I give this card a one star because what's the point in a 3.0 usb interface if it can't transfer large amounts of data consistently? Isn't that the point of buying it in the first place?Looking at the other reviews, it appears some others have recognized the same problem.

Worked perfectly. It did not appear to work on my Matisse USB chipset, but this seems to be a limitation of the Kinect SDK rather than the device. Once I bought a Renesis based USB AiC, the adapter worked just fine

Really, really easy install: Open the case (after disconnecting power, of course), snap in the card, close the case, turn on the power. Windows 11 found it immediately, and the first-time startup might have taken 10 or 15 seconds longer than usual, but that's it. If you need a few more USB 3.0 ports, this is a killer deal.

My order item is a defective Product. it caused all my USB drivers overheated and damage. Moreover, The seller did not want to try to offer any support and resolve the issues. Stay away from this product.

Great price, works. Windows 7 didn't automatically install the driver, but once I figured out which of the 2 folders on the DVD had the right driver (don't use the Atheros driver), it installed fine.

works great with my USB 3.0 4 bay harddrive dock and universal media server sharing files with my Nvidia shield TV 2019 pro

Good for sff cases, but the USB ports are the same width as the slots, so they rub. Also, it would be good to have a 19 pin connector for internal expansion.

I had some issues getting this to work with my Mac - it's advertised as not for Mac, but it DID show up in my system info just fine...so not sure what the issue was, it worked...but didn't - their customer service was very generous though and helped me with a refund as-is. Although this product didn't work for my purposes, I would absolutely deal with the merchant again because of the painless experience!!
