![]() ![]() If you are considering introducing a different manufacturers GPU into your system, then note the difference in cable design before tearing down your unit. Other formats: Although the 8-pin format of the EPS power connector is fairly constant, the 8-pin design of the PCI cable differs between manufacturers to a large degree.The design difference is necessary due to the divergent needs of the parts. The different designs allow power to be carried and grounded along different routes. The cables are similar to EPS ones however, the top left connector of a PCIe cable is rounded off. The 8-Pin PCI Express (PCIe) power cable: This supplies power to a graphics processing unit (GPU).The top left connector has a distinct squared-off pin design that allows connection only to the appropriate parts. This cable became necessary in updated computer models to provide extra power demanded by additional parts. The motherboard already has a main power coupling with the CPU. EPS 12V 8-pin ATX: This delivers power from the CPU to the motherboard.Some have an 8-pin delivery coupling others may be 4-pin or 6+2-pin or a variation of those possibilities. Most come with an 8-pin coupler that connects to the PSU. Cables come in two principal categories and with several designs. Grounds and live power are serviced by separate wires that make up the cable. Each cable has a specific purpose and design. There are several different types of power cables inside your computer that transfer power to various parts. The power cord is specifically designed to carry power to the internal adapters in these machines. The cord offers a convenient means of drawing power from whatever location your computer is near. The IEC power cord has a male end (C14) that plugs into the wall socket and a female end (C13) that plugs into the computer. This means that the power cord is certified by the International Electrotechnical Commission to carry AC 120V power to any household device. Power cords are regulated to IEC 60320 standards. Power cable: Power cables transfer low-voltage DC power to various parts of the computer.Power supply unit: The PSU is an adapter that converts the AC 120V power found in your wall socket to low-voltage DC power.Power cord: The power cord is the wire you use to carry power from the wall socket to the power supply unit (PSU) inside your computer. 8-pin motherboard auxiliary connector Used by an older ATX power supply and motherboard and provided +3.3 volts, +5 volts, +12 volts, 12 volts, and an optional and rarely used 5 volts 20-pin P1 connector Used by ATX Version 2.Power cords and power cables transfer electricity from your wall socket throughout your computer. 20-pin P1 connector Used by an older ATX power supply and motherboard and provided +3. What carries power from the wall socket to computer parts? A connector on the motherboard used to provide additional power to the processor other than that provided by the P1 connector or the earlier 4-pin auxiliary connector. However, its advisable to have at least a basic knowledge of how power is carried via cords and cables from your home or workplace electrical system through the computer. 8 Pin 12V Power Cords and Power Cables: Whats the Difference?Ĭomputers are so common in the workplace and at home that users rely on manufacturers knowledge about using their power. ![]()
