Product Reviews
Rated 4.3 out of 5 by 4reviewers.
Rated 4 out of 5 by It does require the "optional" SATA power connector. Tried the card in two different systems. Drivers installed and all showed well. But, nothing would respond when plugged in. Not a flash drive, keyboard, or disk drive. After plugging in the SATA power connection and rebooting, everything worked as expected. Nice and fast. May 16, 2015
Rated 5 out of 5 by Not bootable I wanted to boot from this card. I have to give it 5 stars because it does everything that StarTech claims. I always want to do something different. April 2, 2014
Rated 4 out of 5 by Power connection not optional Documentation states power connection is optional. My experience with two of these in three separate computers indicates that the power connection is required, even in one with a 750w supply. I could not get any USB devices to work unless the power connection was in place. After doing that everything worked fine. February 25, 2014
Rated 4 out of 5 by Fast, but needs lots a big power supply Have a PC service shop and installed a half dozen of these.  On the machines that had a 400W power supply, USB sticks worked, but USB2.0 and 3.0 docking stations did not.  Once upgraded to a 500W power supply, a single USB dock would work on one port but could not run two docks.  Once finally upgrading the PSU on each machine to 600W, both USB ports worked at the same time with USB2.0 and 3.0 docking stations.  These are definitely power hungry.
