This reminds me of when I was guiding a friend on how to install a video card over the phone... and I talked him through the whole process of opening the weird gateway or HP case, finding the AGP slot and putting the card in. When he put the card in he said 'wait, it all just shut off??'

He had the computer on the whole god damn time and fried it. Lucky it was a POS anyway.

This is the required cable - one of the ones that came with my Seasonic PSU. One end goes to the PSU and the other end connects to the SATA power connector.

The cable is about 2 feet long. I*t also has an intermediate SATA connector so it can serve two SATA devices.

To the best of my knowledge, those molex to SATA adapters only pass 5v to the drives, which is fine for a HDD. The 3.3volt lines are excluded. 3.3 volts may be needed to run some SSDs but not a lot hard disk drives (HDD) use 3.3v.

This is a little incomplete, so let me elaborate:

Molex carries 5V and 12V on the red and yellow wires respectively. SATA power cables carry 3.3V, 5V, and 12V on the orange, red, and yellow wires respectively. Googer is correct in saying that Molex to SATA adapted cable will only have power on the 5V and 12V. This is fine though because desktop HDDs use the 5V for their electronics and the 12V for their motors.
