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.
