StarTech.com 7 Port PCI Express USB 3.0 Card - Standard & Low-Profile - SATA Power - UASP Support - 1 Internal & 6 External USB 3.0 Ports (PEXUSB3S7)

OK so Startech is an unusual brand. They do not employ huge marketing department and you will not see them in every shop, because they cost rather more than typical Chinese electronic and do not appear to have catchy unique selling points - unitil you look into detail. For example, in this case we have a combination of two best of the crop USB3 chips: Renesas uDP720201 (4 channel USB3 controller for ePCI) and uDP720210 (4 channel USB3 hub). Each connector is protected by a reasonably sized capacitor. The bracket features 4 ports past the hub and 2 ports attached directly to controller. On the inside you will find another single port attached directly to controller (the last port of the controller is driving the hub, obviously). You could buy cheaper USB3 controller obviously - but it wouldn't have this many ports and also, most likely, it wouldnt have this quality of components. Of course you could instead buy another Startech controller, 4 port where each port is driven by a dedicated Renesas chip for ultimate performance - useful if you need this much bandwidth. I did not, and wanted maximum number of port instead. It works great. One point to note: due to orientation of USB3 sockets, the USB plugs will fill space of PCI bracket with very little tolerance left. Be sure to plug an USB cable/device/anything into the bracket ports before you close the chassis, otherwise you may need to re-open your computer and readjust the card later.

Pedi uno y me vino con un usb que no funcionaba,solicite un remplazo y antes de que me diese tiempo a devolverlo ya tenia el nuevo en casa.

Achetée pour augmenter le nombre de ports USB d'un PC un peu pauvre en USB, la carte fonctionne parfaitement. Je l'ai installé sous win 8 et une config I5 sur une carte mère Lenovo. Je n'ai pas essayé les drivers livrés sur le CD mais j'ai téléchargé les plus récents sur le site du constructeurs. Les 6 sorties externes fonctionnent. Je n'ai pas testé la prise interne. Livraison rapide.

I was considering 2-port cards for half the price, but 6 external ports with a SFF PC low-profile back plate? Sure, I'll try that. And I'm glad I did! It takes a bit of tweaking to position the card in such a way as to ensure all the ports are able to be plugged into, but so long as your computer's case isn't over-designed around the expansion slots, it should work. I currently have 5 devices connected with no issues! Also, if your peripherals are all self-powered (mine are), then the SATA power connection is indeed optional as I'm not using it (my SFF power supply only had two SATA power ports - one for the DVD and the other for the SSD). The speed is about 5 times faster than transferring data over the motherboard's USB 2.0 ports, and it's consistent (around 90MB/s transferring between two external HDDs), so that is fine by me. It has breathed new life into my older PC.

Installed in my Win 11 machine…flawless install, no problems at all!
