SATA Hard Drive & Legacy Power

[Peter]

I'm installing a Western Digital WD740GD SATA hard drive in a PC I'm
building with the P4C800E Deluxe. For the data connection I'm using a
SATA cable to one of the SATA connectors on the mobo.

The drive has two power connectors on the back edge ... SATA and "legacy."
Given that I am using SATA for data, do I have to use the SATA power
connector on the drive or can I use the legacy connector on the drive? In
other words, is it OK to mix ... SATA for data, legacy for power?

I assume this is OK but just want to make sure.

Use whichever power connector is most convenient for you -
just don't use *both* at the same time or you can damage the
drive.

I know someone with drives like that who is using the SATA
power connectors. In order to insure that he never
accidentally also uses the other power connectors on the
drives, he bought a package of molex connectors and put one
over each of the old style connectors on the drives.

If yours has a legacy plugin on the rear of the drive go ahead. When I
got my MB I recieved a molex to sata power cable, so one is as good as
trhe other.

If I remember correctly the sata power cable has 7 or 9 pins, 2-3 are
negative grounds which are connected to the 1 negative ground on the
molex connector.

Do a search on sata power connectors for more info.

Yeah, you can use the "legacy" plug, provided, you have a
conversion plug to make it SATA like! It's just a plug
difference. +5V is +5V.

My 2 cents.

Yes you may mix.
