    I'll be replacing my 5870 with a 650 Ti Boost soon so I'll have a free 6-pin cable doing nothing. Is it possible to power a 2.5 drive and 3.5 drive in the optical bay using the 6-pin and an internal Sata PCI-e card?

    The 6 pin PCIe connector only supplies 12 volts. Drive power connectors supply both 12 volt and 5 volt.

    I thought the 6 pin cables deliver 75W.

    12 volts at 6.25 amps = 75 watts...
