There are several different types of computer power cables, including AC adapters, USB, Thunderbolt, and VGA/SVGA. Each one has a specific purpose and uses. The power cable is the primary way a computer gets power. It provides power and connects important components, such as the CPU and graphics card. The different kinds of cables differ in wattage and connectors. If you have multiple devices connected to the same power source, you'll need one with different connectors.
Ribbon and twisted pair power cables are both good options if you have a simple setup. Ribbon cables contain four to twelve wires and are used most commonly to connect two network devices, while twisted pair cables consist of color-coded pairs of insulated copper wires. The wire diameters vary from 0.4 to 0.8mm and the number of wire pairs depends on which kind of cable you're looking for. It's best to get the right kind for your needs.
ATX cables supply power to the motherboard and other devices. These cables are compatible with both types. The twenty-pin connector is backward-compatible with the four-pin connector. Most 24-pin cables can be split into two twenty-pin and four-pin connectors. That way, a twenty-pin connector will work in an AGP slot. If your motherboard doesn't have the appropriate connectors, you can use a four-pin cable instead.
Medical-grade Computer power cables are also available. You can get a computer power cord that's rated for medical use, including a battery backup and surge protector. DataPro 9310 computer power cords come with an illuminated power switch and a fuse holder. If the power cable is tangled in the case, you can connect it to a power strip or surge protector, if necessary. A third option is a battery backup unit.
The Molex connector has been replaced by PCI-E and SATA cables, and has become nearly obsolete. Instead of connecting two devices to a motherboard, you'll now find SATA and PCI-E power cables. The SATA connectors are L-shaped and are used to power hard drives and other modern devices. The SATA and PATA cables are compatible with the same devices, and are interchangeable. This makes it easy to change out devices without damaging your motherboard.
Micro-USB cables are commonly interchangeable, so you won't have to worry about buying multiple versions of the same. However, long micro-USB cables can be difficult to carry and can tangle. However, a micro-USB cable with a length of three feet is ideal for charging your device while you're away from a power outlet. Ultimately, the length of the cable depends on your personal preferences and circumstances.
Computer power cables are generally two feet long, with either one of the ends extending more than a meter. If you're using a projector, monitor, or Xbox 360 console, you'll need a longer cord that fits through your video game system. If you don't have a longer cord, you can use a smaller one that is two feet long. The two-meter cable is more than enough to connect a laptop to the console.
