4 Ports USB 3.0 Super Fast 5Gbps PCI Express(PCIe) Expansion Card for Windows Server, XP,7,Vista,8,8.1,10 PCs-Build in Self-Powered Technology-No Need Additional Power Supply(FS-U4-Pro)

Although I can't boot from the server (due to the server not being able to see any usb3), it works as advertised and have several things connected to it.

the on card power supplies radiate severe noise affecting radio and TV nearby the transfer rate is fine but the power supplies had to be modified to stop RFI to TVs and radio. This card is only suitable to those who what their doing !!

Increíble. Esa tarjeta tiene el chip Renesas. Si están buscando como yo una PCIE que te permita DDA a un equipo virtual por HyperV o VMWare está es su mejor opción.

Seamless desktop upgrade. Who doesn't need more USB Ports? I added this card to a Windows 11 machine that had far too few USB ports, and the installation couldn’t have been easier. No extra power supply hookup was needed—the card truly is self-powered, and it was recognized immediately on boot. Within minutes, I had four extra USB 3.0 ports ready to use. Performance has been excellent. Transfers to external SSDs and large capacity flash drives are fast and steady, right in line with what you’d expect from 5Gbps USB 3.0. I’ve tested it with portable hard drives, webcams, printers, and even bus-powered hubs, and all ran smoothly without glitches or power drops. The ports are well-spaced, so even bulkier devices don’t block one another, which is a small but thoughtful detail. The build quality also stands out—it feels sturdy once seated in the PCIe slot, and I didn’t notice any wobble or looseness. One small tip: make sure you seat it firmly and give the drivers a minute to install automatically. For older Windows versions, you might need the included driver disc, but in my case Windows 11 handled everything itself. I also appreciate that the card runs cool; even after long file transfers, it never gave off noticeable heat. That speaks to good design and efficiency, since some cheaper cards can run hot or become unstable. Bottom line: A reliable, plug-and-play solution that expands your USB capacity with speed and stability—well worth it if your desktop is short on ports.

It didn't work in the first PCI-E slot, only charged didn't recognize phone or other device. Checked Device Manager, card was NOT in there so I tried another PCI-E slot and it registered in Device Manager and recognizes devices now. Works without drivers in Windows 10 and it works PERFECT so far. Thanks for keeping my old Pc alive and useful! Updated 9/4/21 After two months it's still working fine. I was very worried about it dying suddenly like in other reviews but only problem has been two failures that required reboot. Card stopped working while being used with no warning. No system crash, just every card on device no longer showed up. Required a reboot and worked fine after that. Updated 10/10/21 The crashes seem to be caused by multiple access demands on the USB card. If you try to play media on two drives at one time you might freeze it up requiring reboot. Otherwise everything is still okay. Updated 2/08/22 the crashes are DEFINITELY caused by multiple calls to the card causing it to overheat and crash. I was using my phone on one USB, playing music on another USB and looking around in a third USB when the crash occurred. My power supply is 800 watt, it is NOT my power supply it is the cards limited capacity to hold a current that causes a fail. An otherwise PERFECT piece of machinery that should have been shop tested more with a greater capacitor.
