SATA Drive With Legacy Power

I'm installing a Western Digital WD740GD SATA hard drive in a PC I'm
building. For the data connection to the motherboard I'm using a SATA
cable. For the power connection do I have to use the SATA power connector
on the back of the drive or can I use the "legacy power" connector on the
drive? In other words, is it OK to mix ... SATA for data, legacy for
power?

Yes. Just don't connect both legacy _power_ connector and SATA power
connector at the same time. There should be a warning label to that
effect on the drive.
 
"Legacy power" is +12v, +5v, and ground.

"sATA power" is +12v, +5v, +3.3v, and ground.

As long as your sATA drive doesn't actually make use of the newly
available +3.3v, you should be OK.
