Rated 5 out of 5 by from Good card, good support.. Good company, I had issues getting the high power 3amp charge current from the card, but it turned out that the USB-C cables I had bought (not cheap) were a scam and only supported USB 2.0 speeds, and higher power was not being negotiated. I got another cable, and managed to get at least USB 3.0's 900ma, with the computer showing a USB 3.2 device connected, but still didnt get 3 amps.. I suspect that the issue is still negotation in windows, as in BIOS I was able to draw over 10 amps from the card with no problem!. Sadly it still locked at 900ma after entering windows, but I cant fault the card for that. Im sure its negotation between the USB device, and the windows locking the power at 900ma.. Anyway. Good company, would buy again. Not sure if this could be resolved with different drivers considering it works in BIOS!?

Rated 5 out of 5 by from Easy Install. Works perfectly...! I just installed this and it was easy. I used the provided low-profile bracket after removing the Full-Height Bracket. Then I connected the 15 pin SATA Power Connector to it so I would have extra power to charge connected devices. But that is not necessary if you want to use the port for data only. Now I have 2 additional USB 3.1 Type C Ports and I can connect any USP C port device to it.

Rated 5 out of 5 by from Worked fine in HewlettPackard Z2 G9 workstation... ... after updating the firmware using an older desktop PC. After the first install in a very recent HP Z2 G9 workstation, the card was not recognized by the Windows 11 Device Manager. So I used another older desktop PC to update the card firmware succesfully [interestingly, the card did not work correctly anymore in this older desktop PC after the firmware update...]. Reinstalled the updated card into the Z2 G9 machine and everything worked flawlessly (without any additional driver install)! So be aware of this possible quirk with latest generation PC's. Paul
