What kind of power connector does a floppy drive use?

Floppy drives utilize a mini-molex power connector, which is a smaller version of the standard Molex connector typically used for powering larger peripherals like hard drives and optical drives. The mini-molex connector is designed specifically for the lower power requirements of floppy drives while maintaining compatibility with older power supply units that were commonly used in computers prior to the widespread adoption of other connectors.

Other types of connectors mentioned, such as the standard ATX power connector, are larger and designed for more modern power distribution in contemporary systems. The PCI power connector is intended for powering PCIe cards, and the SATA power connector is designed for newer drives like SSDs and SATA hard drives. These connectors do not match the specifications or size of the mini-molex used in floppy drives. Thus, the mini-molex is the correct choice for providing the necessary power to a floppy drive.
