How do I externally power a SATA drive?

Specs: Microsoft Windows XP Professional, 1.8 GHz / 503 MB
I have recently purchased the Sony Optiarc AD-7240S optical disk drive. It is an internal drive, but I want to make it external, without paying for an external enclosure as they're too expensive. I already have a SATA Data to USB converter, but now I need a SATA Power cable/adapter. What am I looking for? Will I need something like:

"SATA Power to Mains Adapter"?
"SATA Power to USB Adapter"?

What exactly do I need?
What voltage will the drive require to function?

Thanks in advance for any help.

SATA power connectors provide three different voltages (3.3, 5, and 12v). USB will not provide enough amperage for a 3.5" drive, so you would need to power it from a power brick or an old computer power supply. I don't think I've ever seen a power brick for SATA, but I've seen a couple for Molex like this:

An adapter may be able to convert the connector to SATA if your drive doesn't have dual connectors. Many manufacturers don't actually use the 3.3v lines in their drives anyway, but you may want to check if your particular drive does or not.

If you want an external, return the internal drive & exchange it for one. Otherwise, buy a 5.25" external case to mount your internal drive. If you do it your way, it's not gonna be very portable because of all the cables, adapters & power supply you'll have to carry around with you.

Or how about just installing the drive in the PC?
