Update on this issue, the initial card I bought needed an internal SATA power, which I could not get on a R720 appliance but I was able to get another PCIe card that does not require internal SATA power and that worked well.
I want to install a PCI-E card with USB 3.1 for my Dell R720 server and I need SATA power for the card to work. I would like to know if this adapter can be connected to the onboard 8-PIN GPU power connector. I will really be glad to get a response about this.
