First, you may have to buy Molex adapter (most new motherboards don't have it). Second, DO NOT use the CD that comes with the product. Go here: [...] and download the latest driver for "VL800 & VL801 USB 3.0 Host Controller" Shutdown the PC, install the card and start up. Please run "SETUP.exe" from the drivers you just downloaded before. Installation is completed. You may start using your USB 3.0 ports now.
One other thing to note - even though manual says the power is optional to attach to this card, however the card will NOT work until you attach the power cable. (the card will be recognized, however, any devices connected to usb 3.0 port will not be recognized, if the power cable is not attached).
For the external hard drive connected to these USB 3.0 ports -- the throughput I'm seeing is about 125/80 MB/s (read/write). No disconnects or any issues with using these ports at all.
Hardware - excellent; Syba customer service - nothing after two days.
After trying three different brands, Syba was the one that finally worked on my 2012 H61 chipset-based PC under Windows 10 but it was trial and error and took several steps: 1. First, I updated the BIOS in my older PC 2. After installing the card and drivers, the Device Manager showed that "the card did not start" 3. Then, I entered BIOS and disabled the onboard USB, thinking that it may help. Rebooted and the card was "working normally" in Device Manger. However, the USB 3.0 ports didn't work. 4. Finally, I attached the power cable to the PCIe card, renabled onboard USB and rebooted. That was the solution; the USB 3.0 ports need the extra power; all the 8 onboard USB 2.0 ports also work.
Windows 10 had no problem finding drivers but I also did an "update driver" with the latest Renasas (ex-NEC) drivers from their site. The lesson is that...
I installed two different boards each with two USB 3.0 ports; neither card worked reliability (even after upgrading the firmware). Each card had a NEC/Renesas controller on it. In desperation I bought this card. This Syba four port card worked perfectly right from the gitgo. It has a VIA controller on it. Fast, simple install. Reliable operation. Full USB 3.0 speed. Four ports. Excellent.
