1. the ATX power connector (20pin + 4pin): 20/24 pin ATX connector used to connect the power supply unit (PSU) to the motherboard. The old version of ATX motherboard is still using the ATX 20 pin connector, if we use the latest motherboard already requires ATX 24 pin connectors. Konetktor consists of 2 parts. The first section totaled 20 pins and the second part 4 pins. If we are using a motherboard that has the mix between 20 + 4 pin connector.
2. AT power connector (12 pin): this connector is used for motherboard and Pentium II class. The connector has 12 separate wires are grouped into 2 parts. The first part is called Connectors P8 and P9 called the second part. Each connector has 6 cables. To avoid errors in the installation, we simply bring together the connectors have black cables in the middle.
3. this Connector: Molex connector used source power for the hard disk and cd drives. Sometimes some manufacturers also make fan/cooling fans, lights and other accessories using this connector. This connector has 4 different cable colours, i.e. red, Yellow and Forests. Each color has a different voltage sources.
4. Berg connector: mini size connectors of the Rows. This connector is used for special Floppy Drive or any external audio card. The colors used with rows of connectors, Yellow (+ 12V), red (+ 5V) and black (0V or Ground). Due to the use of this connector is rarely, hence each PSU only has 1 or 2 at most.
5. ATX 12V (Intel) 4 pin connector: this Connector is used mostly by the users who use artificial Intel Processor. The function of this connector is an additional manpower as a provider of 12 V for Pentium 4 CPU. So on a Pentium 4 down, this connector does not need to use. Now some AMD motherboard ATX connector also have used a 12V.
6. the 6 pin PCI-E connector: this connector is that one is indeed rare for all PCs. Usually people who use the PSU it is people who work in the field of Multimedia, especially Video. Because this connector is used only as a power Enhancer for the video card uses the PCI Express slot. If we use this type of Card Videoa, of course we must have a PSU that support for this connector.
7. SATA Power connector: this connector is the newest type of commonly used to power on the Hard Disk is SATA (serial ATA). This connector is connected through the rows of connectors (extended).
