    I've seen these adapters that let you power a SATA drive from a standard 4 pin power connector used on IDE drives. But the power connector for SATA drives has a 3.3v lead and the 4 pin plug only supplies 5 and 12. How can those adapters work then? Its just a cable.

    SATA drives have two connectors, one that uses the MB power, the other that uses your regular power. The regular power connectors/SATA cables are bigger than the SATA cables. I'm guessing it's simply to reduced the load on the MB.

    OMFG where do you get your information? Because it's so wrong it's comical! Name a consumer desktop board that can support a SATA drive's power requirements? NONE!

    So do SATA drives require 3.3v power or not? The new SATA power connector supplies it but obviously an adapter getting power from an older connector is not going to supply it. Would an adapter work on some drives and not others or is the 3.3v there for future use?

    Yes you're right, I was thinking of something else.

    Now please stop being such an asshole to everyone.
