But in the future, 3.3 volt drives may become common so you need to be careful when using SATA power cables which don't implement 3.3 volts. That may be because there are too many people using adapters so the drive makers don't want the headaches which come with using 3.3 volts. Currently, SATA drives rarely use 3.3 volts. (84) Nippon Labs SATA to Molex Power Adapter SATA-FM SATA 15 Pin male to Molex 4 pin female adaptor Cable for SATA I and SATA II Hard Drive Model SATA-FM, 7 Inches. Find Computer Products, Electromechanical, Electronic Design, Electronic Kits & Projects and more at. These are usually Y-adapters that have the four-pin drive connector on the other end. 3 pin molex connector available at Jameco Electronics. Pins 1, 2, and 3 are optional as well, as evidenced by some adapter cables that connect the drives to older PSUs. 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) Molex connector 2 pins 2,54mm crimp connector (Arduino, PCB), male to female connector. PCI Express Adapter Video Card Power Cord 4 Pin Molex IDE to 8 Pin PCI Express Power Cable. The same physical connections are used on 3.5-inch and 2.5-inch notebook hard disks. 4 pin Molex Female Socket Connector Auto Wiring Harness Cable OEM ODM. The name comes from the Molex Connector Company, which pioneered the two-piece electrical connectors that became standard in computers and other electronics. One pin from each of the three voltages is also used for hotplugging. Molex Connector: A Molex connector is a common type of connector used to power internal computer components. 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). The SATA standard specifies a power connector sharply differing from those used by PATA drives and many other computer components. Molex 67581-0000 used for cable connector and Molex 67582-0000 used for terminals connector.
