molex for IDE devices and sata power connector for SATA devices
the optical drive will connect to the power supply with a connector called molex connecter it is a 4 prong connector
There are two kinds in common use:Molex - an older standard, but still commonSATA - Serial ATA, a newer standardSee the related links for pictures.
a sata power connector is normally used for powering sata dvd drives as well as sata hard drives and ssd drives
The power connectors used by both 5.25-inch and 3.5-inch floppy drives are 4-pin connectors. The larger connector--used by 5.25-inch drives--is called a Molex or peripheral cable. This type of cable is also used by IDE/ATA hard drives and optical drives. The smaller 4-pin cable used by 3.5-inch floppy drives is generally called a floppy power cable.
A Molex power connector is a 4-pin power connector found in most computer power supplies. It is used to provide power to large internal drives like hard drives and CD/DVD drives. They are slowly being replaced by SATA power connectors, which are easier to install can cannot be inserted incorrectly. They should not be confused with a Berg connector which is much smaller and is used to power floppy drives. The molex connector is used for IDE drives
A Berg connector is used for providing power to floppy drives and sometimes other peripherals.
A "Berg" connector.
SCSI Harddrive:80-pin Connector The SCA interface was designed to provide a standard connection for systems using hot swappable drives. SCA interface drives connect to a SCSI backplane that provides power, configuration settings such as SCSI ID, and termination of the SCSI bus.
This is commonly referred to as a "Berg connector", after it's original manufacturer, the Berg Electronics Corporation.
The atx 12 connector is one of the motherboard power connectors and used for 12 volt power connect for cpu voltage regulator.
