Are SATA hard drives powered directly from the power supply?

Question

I am building a computer system and am new to SATA technology. I am purchasing my first SATA hard drive.

The motherboard comes with the SATA data cable. What I want to know is if the power supply plugs directly into the SATA drive or does it need a special cable with a molex on one end?

On my hard drive wires, there are 2 different power cables besides the standard molex connectors. Would those be SATA power cables? They are black connectors and very thin.

Answer 1

The SATA drives do connect directly to the power supply just as the PATA drives do. The connectors are different though. They are flatter and instead of 4 pins, they have 15 tiny contact points.

If your power supply does not have the SATA connectors, you can get an adapter that changes the 4-pin to the 15-pin.

Answer 2

Internal SATA drives will be powered through the power supply of the computer just as ATA drives were. However, SATA drives have a different power plug than ATA does. But... Some SATA drives will come with both the new SATA power plug and the old AT style Power plug (the larger four-pin white plug on the power supply), and you can choose which one to use. The new SATA power plug on your powersupply will be flat, wide, and black. 15 pins. The below link shows some pictures of the power plug that would be used. It's not impossible to have a motherboard with the SATA power coming out of it, but I've personnally never seen it and it's highly improbable.

Answer 3

The SATA drives do get their power directly from the power supply. They use a flat, black, 15 pin connector, so it sounds like you might have the correct connector on your supply. If not, there are adaptors available.

Answer 4

it would act precisely the comparable as in case you had a real SATA connector. i actually offered an IDE to SATA adapter because of the fact my motherboard in basic terms had one IDE slot and that i necessary that for my dvd- rom drives.

Answer 5

Use only SATA Cables!

To place Active@ KillDisk Pro onto a floppy disk type the following at the command prompt:
COPY G:\KILLDISK.EXE A:
COPY G:\DOS4GW.EXE A:
The above assumes that the G:\ drive is the bootable CD-ROM drive and the A:\ drive is the floppy disk drive.
DOS4GW.EXE is a required file for Active@ KillDisk, Active@ UNERASER and Active@ Disk Image.
