Koutech2-Port SuperSpeed USB 3.0 PCI Express Controller Card (2xExt) with Regular and Low Profile Brackets and 15-pin SATA power connector

Using the included driver, this product works perfectly providing super-speed USB 3.0 to an older Dell computer (Windows 7) with PCI Express slots. I took a star away because it's a maze of directories to find the driver to install; the included paper printout indicates what driver to use. The CD contains drivers for a wide range of products.As a product, it's well made, reliable, and works great so far!

I was skeptical about using add-on 3.0 usb cards. I have purchased two different vendors' cards and can now say this one by Koutech is great. It has worked constantly for me. The other one I purchased does not always get read by the computer at startup, but this one does and never fails. Works flawlessly. I bought two of them. They work in all PCIe slots.

worked instantly when installed, exactly as described. would recommend this card to anyone wanting to upgrade an older PC that has only USB 2.0 to the faster USB 3.0

I wanted to get another PEU436 4 port like I have in a Win7 64 box, but ... this 2 port PEU230 is the one they recommend for Win2003 server.Zero issues, just installed the latest drivers from their site and I was up without a reboot.

Easy to install and works great
