6) Source Connectors (ATX 20/24 Pins, ATX P4, Molex, Sata, PCI Express) - ATX Connector 20/24 Pin: It is the one that feeds the motherboard, formerly of 20 pins, the current standard provides 24 pins. It is almost always composed of a block of 20 pins, to which we can add a block of 4 pins. This in order to respect the compatibility with the old plates with 20 pin connectors. -ATX P4: "ATX P4" (or also ATX 12V), connects to the motherboard and is exclusively for the processor power, without it it is impossible to start the computer Currently most motherboards have 8 pins, due to the increase in CPU power. -Molex type connector: The most classic and even present in all computers, sometimes used directly on the motherboard, serves to connect the hard drive and all types of drives (reader, recorder). -Sata: It is present in all modern computers, it is used to power hard drives and recorders under the SATA standard. - PCI Express connector: The power of graphic cards does not stop increasing, many of them need a direct power supply of the main block (sometimes even two). This is the function of this connector. Initially of 6 pins, more and more we can find them of 8.
