Commonly referred to as internal Molex connectors on a desktop computer. It is used for peripherals that require more amperage than that provided by the data cable such as:

• Hard drives (IDE, SCSI and SATA)
• Units diskettes (3.5 'and 5.25 ")
• Optical drives (CD, DVD and Blu-Ray)
• Video cards (PCI-e plates, PCI and AGP)
• Cooling systems (air and liquid)
• Modding circuits (LEDs, light pipes, etc.)
• Naturally, there are two types of Molex connectors, a male connector and a female connector. Plugs are used to branch outlets and split them into two but most of the time are integrated into the PCB peripherals.

The electrical conductors exiting the power supply toward Molex connectors have colorsdistinguish:

Serial ATA or SATA (acronym for Serial Advanced Technology Attachment) is a data transfer interface between the motherboard and some storage devices such as hard disk, regrabadores readers and CD/DVD/BR, SSDs or other high performance devices are still being developed. SATA I Frequency: 1500 MHz Bits: 1. Bits 8 Real Speed: 150 MB/s. SATA II. Frequency: 3000 MHz Bits: 1 bits 8 Real Speed: 300 MB/s. SATA III Frequency: 6000 MHz Bits: 1. Bits 8 Real Speed: 600 MB/s eSATA. SATA type connector for connection of external peripherals.
