Got a new SATA drive that you need to connect to a system with an older power supply? Here's a solution.
This is an adapter is for connecting internal storage devices that require 15 pin SATA power connectors to Power supplies that only have 4 pin molex power connectors. i.e. YOUR DRIVE IS A NEWER SATA, BUT YOUR COMPUTER IS AN OLDER ONE WITH MOLEX.
Warning: Molex connector provide 12V and 5V power lines, but not 3.3V required by some SATA drives. Make sure your drive does not require a 3.3V power connection before purchasing this adapter.
