A DVD-drive inside my computer is connected via a SATA "combo" (power+data) connector. I want to attach an SSD to a SATA PCIe card (7-pin connector I assume) but need to power the drive as well. Since there are no unused power connectors inside the computer I'm thinking I can "tap" power from the DVD-drive, and feed that into the SSD. I imagine there must be some sort of adapter connector/cable which plugs into the DVD-drive, extracting power from it while still keeping the existing power/data connection to the DVD-drive. I thought I found it here: Camera Canon EOS 20D Focal Length 60mm Aperture f/5 Exposure 1/160s ISO 100 Camera Canon EOS 20D Focal Length 60mm Aperture f/5 Exposure 1/160s ISO 100 ..... but it looks like the rightmost drive relies on a 7-pin data connector rather than a 7+15 pin "combo" connector which I have connected to the DVD-drive. Are there any suitable adapters/cables for this available?
