One pin from each of the three voltages is also used for hotplugging. The supply pins are ganged together because the small pins by themselves cannot supply sufficient current for some devices. Pin 11 is used in newer drives for staggered spinup. Each pin should be able to provide 1.5 A. Each voltage is supplied by three pins ganged together, while ground is provided by five pins. The seemingly large number of pins are used to supply three different voltages: 3.3 V, 5 V, and 12 V. However, it should be fine to quote it and link, or rework / interpret the data into the page.Ĭopied from the Cables and Connectors section of I dont know how to handle any legal aspects of copying from wikipedia, if that would require to release this page as gnu-FDL, etc. The wikipedia article for sata includes information about the data and power pinouts, clarifying some things here. These are usually Y-adapters that have the four-pin drive connector on the other end Pins 1, 2, and 3 are optional as well, as evidenced by some adapter cables that connect the drives to older PSUs.
