I get super flexibility from this product. Its length is enough for me to pull my PC a little further away from my desk for the most comfortable sitting position.

For build quality, C2G has paid great attention to the maximum durability of the product by altogether casting this heavy-duty 18 gauge wire. I use it for more than 6 hours of daily work, and it only gets warm at the end of the cord.

Buying Guides

Computer power cord

You’re probably very familiar with the residential electrical wiring model. However, there are a few critical factors for you to consider below.

Types of cords

There are many types of computer power cords available in the market today. Some of the most popular versions include:

  • SATA power cable: This IDE standard connects the motherboard to devices such as hard drives and optical drives. This type provides fast and very efficient data transfer performance.
  • Display power cable: It is ideal for network output display purposes. Standard monitor power cables include DVI, VGA, and HDMI.
  • Rugged drive power cable: Not all power cables are compatible and work well with different hard drives. The ideal hard drive cable is essential, so you must double-check your hard drive type to make the best decision.

Wire gauge matters

Considering wire gauge matters is a prerequisite for choosing and adequately using computer power cords. As a rule, when used on equipment with high energy consumption, light or medium models present a potential fire hazard.

Power cords’ components

The wire core and the protective cover of the power cable are the two main components of power cords. Continue reading to understand more about them.

I believe using aluminum power cable instead of copper cable is a smart investment for power transmission efficiency and durability.

As for the outer sheath, in addition to the aesthetic and scientific design, ensure the version you choose is durable enough to protect the inner cable core.


Does it matter what power cord I use for my PC?

Products from different brands and brands often have separate ways of connecting. So, it is better to use the cable that came with the power supply.

Are all power cords for computers the same?

Yes. Due to differences in plug configurations worldwide, computer power cords are not the same.

What is the standard computer power cord?

The standard computer power cord on the market today is C13/C14.

Are thicker power cords better?

The short answer is yes. A thick power cord is better if you need to transmit a lot of power over long distances.

Which is better: a ten gauge or 12 gauge extension cord?

Their thickness is the most obvious difference between 10-gauge and 12-gauge extension cords. The thicker the wire, the lower its gauge.

Many studies show that low-power devices work well with 12-gauge extension cords. 10-gauge is generally suitable for devices that require a low gauge.


In short, the best power cords come in many different types and sizes, each with advantages and adaptations to its intended use.

If you love the convenience and have a high requirement for a long power cord, the Amazon Basics Cord is the ideal choice. Besides, don’t ignore Cable Matters if you want ultimate safety.
