    I have a Thermaltake Black Widow 850W modular power supply in my current computer. I have been looking for hours trying to find the right product for my question.

    http://www.newegg.com/Product/Product.aspx?Item=N82E16817153106

    My PSU uses 8-pin PCI-e power to power all connected devices (ex. 8-pin PCI-e connection at the PSU to a cable with SATA connectors for hard drives, etc).

    My question is: are there cables somewhere that are PCI-e (6 pin or 8-pin) to cables with SATA connectors on the other end to power HDD?

    All I can find are cables that are SATA to PCI-e (the cable that is connected to the PSU is SATA and transfers the power to a device using a PCI-e like a GPU)

    The specs for your pw supply show 7 sata pw connectors. Why not simply use those?

    I don't need one cable with 4 or 5 sata connectors on there when I only need 2. I would like psu->pcie connector->1 or 2 sata power connectors->my 1 or 2 hard drives... Hope that makes sense

    Well it now makes sense however I have never seen what you are asking about. Just use the sata connector and tie up the unused ones; store the tied up connectors in an unused 5 1/4" bay.

    There's actually technical reasons why such cables don't exist. PCI-Express connectors only carry 12 volt, no 3.3 or 5 volt that a SATA power connector has. Plus graphics card draw huge amounts of power and they are best not shared with other devices on the same cable.
