Pros: Best solution for my corsair 650d case, which had usb3.0 pass through instead of the internal 20pin usb 3.0 connection.

Cons: The first card failed to start, but after a very quick and easy email/chat with sedna, they sent another completely free which arrived in a few days.

Overall Review: I would recommend this card to anyone who needs a solution like mine. Sedna met my expectations with sending a replacement and the second card works flawlessly.
