Advertisements So I shucked an easystore 8tb from best buy for the WD Red and had planned on using the power from the included usb3 interface card to power the drive with a sata extension power cable. It appears the interface card does not supply power without the serial cable connected also? Anyone familiar enough with circuitry to come up with solution to trick interface into supplying power? I pulled older interface card from WD ext drive and it does supply power without the serial data cable attached. Thanks for any suggestions.
