Pin 11 can be used for activity indication and/or staggered spin-up. If pulled down at the connector (as it is on most cable-style SATA power connectors), the drive spins up as soon as power is applied. (3.3 V Power, Pre-charge prior to SATA 3.3) The same physical connections are used on 3.5-inch and 2.5-inch notebook hard disks. One pin from each of the three voltages is also used for hotplugging. This is because the small pins cannot supply sufficient current for some devices. The seemingly large number of pins are used to supply three different voltages - 3.3 V, 5 V, and 12 V.Įach voltage is supplied by three pins ganged together (and 5 pins for ground). Intelligent TurboWrite maintains long-term high performance. It is not needed, as SATA equipment can work with 5V as well, infact, there are plenty of Molex-SATA adapters, which lack the 3.3V. SATA connectors have 5 wires, because they also supply 3.3V. 24-pin Motherboard Power Connector Pinout 15-Pin SATA Power Connector Pinout ATX Power Supply. Samsung 870 EVO achieves the maximum speed of SATA interface. Step 3: Remove the SATA Power Connector From the Donor Cable. The SATA standard specifies a power connector sharply differing from those used by PATA drives and many other computer components. The motherboard fan connector is a Molex KK connector. Molex 67581-0000 used for cable connector and Molex 67582-0000 used for terminals connector.
