What You Need to Know About Computer Power Cables and Adapters

 

You've probably seen a computer with a bunch of computer power cables hanging from it. They might look like ordinary cords, but they're actually a necessity. They're essentially wires wrapped in plastic that connect to a power source and then supply power to the motherboard and other components. Some of these cables also have power switches on the back. You can flip them off to stop the power flow. A computer without any computer power cables is almost useless.

Depending on the intended application, computer power cables can be made of different materials. Some cables are made from aluminum conductors while others use stranded copper or solid conductors. A cable may also be made with an uninsulated conductor that serves as a circuit neutral or earth connection. Another difference between a power cable and a ribbon one is the number of conductors used. A ribbon power cable can have anywhere from four to 12 wires. It can also be a ribbon or a twisted pair. Each has its own benefits, and they all have a variety of features.

The connectors used on Computer power cables are categorized into different types. Some cables are universal and compatible with most models. Others are designed for specific devices. Some computer power cables are made for a specific region, while others are meant for use worldwide. To use an IEC power cord, you should first understand the standard power cords used on your country. These will have different voltage ratings, so you should know which type you need. Those that work with European outlets should use an IEC C13 cable, which is the most common.

Another way to determine what type of computer power cable you need is to identify the type of hard drive. A SATA cable fits inside a SATA hard drive and will power two devices at once. A PATA power cable has only four or six pins, while a SATA cable has eight pins. A PATA power cable supports two devices. Some of these cables may combine with an IDE/PATA DVD-R drive.

If you're a regular gadget buyer, you'll likely collect a bunch of micro-USB cables. Because these can be interchanged, you may not need separate cables. Buying the cheapest one is tempting, but don't do it. They might be tangled and a tripping hazard. You should only buy the cable that meets your needs. When buying micro-USB power cables, don't be tempted to buy one that's too cheap.

The four-pin floppy drive power cable was first introduced when computers started using 3.5-inch floppy drives. These days, they serve as auxiliary power cables for video cards and other computer peripherals. These cables are made of 20 AWG wire with tiny connectors and are therefore only useful for low-current purposes. It's also limited to connecting peripherals such as speakers and add-on fans. The four-pin floppy power cable is a very simple cable, and is still used for a small number of devices.
