Review on 🔌 FebSmart USB 3.0 PCI Express Expansion Card for Windows Server, XP, Vista, 7, 8, 8.1, 10 PCs - 2 Ports, Super Fast 5Gbps, Build-in Self-Powered Technology - No Additional Power Supply Required (FS-U2-Pro) by Tim Ram

I installed this on an older server to support an external USB 3.0 enclosure for backup and it just works. There were no drivers to install (Windows Server 2016) and it showed up with no problems. So far, so good. Unlike many USB 3.0 cards that have an additional power connector, this one doesn't. Which is great for me since the server I'm using doesn't have standard power cords anyway. But just be aware of that beforehand. Don't plan on using them for high-end devices - only for low-power devices (USB 2.0 limits) or devices that have their own power supply, like a larger external enclosure. It comes with a floor to ceiling mount that you can swap out for what I did. Easy replacement of the pre-installed full-height bracket.
