PC 4pin Molex Peripheral Connector to SATA (Serial ATA) Power Adapter Cable

The 6-inch Serial ATA Power Adapter Cable lets you connect your serial ATA device to the standard 5.25" 4-pin molex power connector. The cable consists of one 12V, one 5V, and two grounding connections. Connectors: 15-pin Serial ATA Power to 4-pin internal power Connects any Serial ATA drive to a standard internal power connector About Serial ATA Lower Voltage - Parallel ATA is based on TTL signaling, requiring integrated circuits to tolerate input signals as high as 5 volts. Soon, integrated circuits manufactured on the leading manufacturing processes will not be able to efficiently support 5 volt signaling voltages. With the upcoming fine lithographies, it will not be practical to support 5 volt signaling tolerance. Serial ATA manages this by reducing signaling voltages to approximately 250 millivolts (0.25 volt).   Pin Efficiency - Currently, the parallel ATA interface has 26 signal pins going into the interface chip. Serial ATA uses only 4 signal pins, improving the pin effi
