    I purchased a Seagate 2TB drive Barracuda LP HD ST32000542AS for my Home Theatre PC.
    I am out of SATA power plugs, but have several 4 pin molex. I was looking at monoprice.com at this adapter: http://www.monoprice.com/products/p...=10226&cs_id=1022604&p_id=5185&seq=1&format=2

    In the fine print, it says to make sure your hard drive doesnt require the 3.3V supplied on the orange wire. I looked at the spec sheets for this drive, and while it listed the pinouts of the power plug including the orange wire, it didnt state whether it was nessessary. Seagate has not answered an email request as of yet. Does anyone on here know the answer?

    Only +12 and +5 VDC required for desktop models.

    +3.3VDC is reserved for future small factor (think for notebook) models.

    If you need total evidence - newegg has a picture of it, where the two rails and both current printed.

    Already ordered it. (Im fast). Im sure it will work given your explanation. If not, hopefully it will work on one of the two WD20EADS or the 500GB Samsung already in there.

    I'm assuring you - it will works.

    I'll bet $100 against anyone who will say NO. ;)

    I've got 6 internal hard drives in the machine I'm typing on; but only had 4 SATA power plugs. I used the single version of these converters to accomidate the power requirement for the other 2 drives. They work just fine without any modification/rewiring at all....
