I want to correct a review from reviewer Little Dragon on 9/8/2008. He incorrectly stated "...this connector will change your standard female Molex power cable connector to the required male SATA power cable ..."
Monoprice's description correctly states that the cable ends are Molex male and 15-pin female (not 15-pin male). I confirmed with Tech Support.
Others have pointed out that the range of power and power management is limited due to going from four pins to 15 pins. I was upgrading my old computer, and had molex power connectors. I put in a new Mother Board, AMD-A8 processor, SATA hard drive, and a SATA SSD drive (wonderful addition), and a SATA DVD drive. This allowed me to reuse my old case/power supply. It has been over two months with no problems.
