Drive Power Connectors: Molex, Berg, SATA



There are drive pwr connectors and Mobo power connectors in a PC.

Drive power conns are stdized in size, shape, placement and the voltage carried through their wires.
  • Peripheral conns, (Molex typically conn HDDs and CD/DVDs to the PS (see left).
  • Floppy conns (BERG, mini-Molex) conn are smaller
  • Serial ATA (the new version of IDE) are the third kind. (See right).
These connectors are "keyed" - they can be inserted into drives in only one orientation. This ensures that you connect right power inputs to the correct point on the device.
