StarTech 4 Port PCIe SuperSpeed USB 3.0 Controller Card Adapter w/ UASP

I have had good experiences with previously bought serial and parallel port expansion cards with low profile brackets from Startech. But on this card it is either the wrong dimensions on the bracket or something with the hole pattern on the card. When mounted, there is a 3-4mm gap left causing me to bend the mainboard when the latch holding the card is locked. Because of this I'm not comfortable using this card. I have tested with a random ethernet card also with a low profile bracket, and this fits just fine in the same computer without bending the mainboard noticeably.

I had purchased another product which I returned due to quality control issues and I am so glad I did. I am impressed with the quality of this product and installation went as it should...

The four USB 3.O ports are aligned vertically which allows for more ports, than say one with horizontal ports.

I've been running this card well over a year and beside having to reinstall the drivers once (power failure) this card has been flawless. My machine only has USB 2.0 ports so the speed upgrade was quite dramatic, I don't think you quite get the full 5gbps as advertised but my external USB drives do outperform my internal SATA II hard drives.

This card works brilliantly for my Oculus Rift (VR). It supports windows 10, but make sure you don't install the old drivers from this website. The new ones are automatically installed by windows 10, and are (at the time of my writing) driverversion 10.0.16299.125, dated 07.12.2017. Make sure your motherboard has enough PCIe-lane bandwidth left for a for x4 card - as well as a x4 slot, of course. Some motherboards downgrade to x1-speed when other slots are taken. Doublecheck your motherboard manual! Also keep in mind to plug in power from your PSU, otherwise the card won't work as well.

Test the card on server 2016, will not accept the drivers from OS or the cd, make a firmware upgrade, the OS can now find a driver, only run USB 2.0. Try to install the drivers from cd, the system accepted the drivers, but only run usb 2.0 Have try a usb 3 pen and a usb 3 harddrive.

I have been using the USB 3.0 PCIe card adapter for about 6 months and it installed easily and has worked flawlessly. The half height card bracket came with the kit and enabled me to use it in my ASUSPro Series system unit.

I got it a year ago and it didn't work with my hp but I blame the mobo in that. It works on my main rig so it's still functional as extra USB ports.

The price was right, and it is small enough to fit in with my rather large GTX 780Ti graphics card. The Pro Flight Sim instrument panels require USB 3.0 ports; all eight work perfectly with two 4 port StarTech PCIe cards.
