When you're managing IT infrastructure—whether it’s computers, servers, monitors, printers, scanners or A/V equipment—having the right power cords available is essential to ensuring reliability and minimizing downtime. Whether you're outfitting a new workstation or replacing a lost or damaged cord, the right choice can offer benefits beyond simple replacement, such as improved durability, ideal length or better electrical performance. 

It’s easy to get overwhelmed by all the specs. While factors like cord length, jacket material, plug orientation (straight or angled) and gender are usually straightforward, others require closer attention. To make confident purchasing decisions, focus on four critical areas: configuration, plug type, power draw and wire gauge. 

Configuration 

A cord’s configuration refers to the plug and connector combination on each end, and with over 80 standardized configurations out there, choosing the right one ensures compatibility with both your power source and your device. 

One of the most widely used is the 5-15 to C13 configuration, featuring a standard NEMA 5-15 plug on one end and an IEC C13 connector on the other—perfect for most computers, monitors and A/V equipment. In data centers, the C14 to C13 configuration is popular because it allows power to flow between two IEC components, such as from a server’s auxiliary port to a monitor. 

Some devices use more specialized cords, like Mini DisplayPort, commonly found in compact or portable electronics. You’ll also see the 5-15 to 5-15 cord, which functions as a traditional extension cord and is widely used in office environments and for small appliances. For setups that involve Chinese outlets, the GB2099 to C13 cable allows connection to electronics that use a standard IEC C13 input. 

Plug Type 

The plug type determines compatibility with wall outlets, especially important for international deployments. Globally, there are 15 recognized plug types, labeled from Type A through M, and understanding where each is used can ensure smooth operation abroad. 

For instance, Type I plugs are standard in Australia, New Zealand and parts of China. They pair well with C13 connectors for powering PCs and monitors. Across much of Europe, the Type F (Schuko) plug is prevalent, and it’s often used with C5 connectors for laptop power adapters. In the UK and Ireland, Type G (Schuko) reigns, with its distinctive rectangular pin configuration, but it also appears in various other countries that follow British standards. 

Power Draw 

Power draw refers to the amount of electrical current a cord can safely carry, measured in amps. Using a cord with the correct amp rating isn’t just a technical detail—it’s a safety concern. Too low a rating can cause overheating or damage to your equipment. 

For smaller electronics, a 2.5-amp cord is typically sufficient—ideal for laptop chargers and lightweight consumer gear. Most mid-range office equipment like monitors and printers will require a 10-amp cord. Higher-draw systems, including desktops and rack-mounted components, generally need 15-amp cords, while the most power-hungry applications—such as servers and laboratory equipment—call for 20-amp rated cables. 

Wire Gauge 

The wire gauge, or AWG (American Wire Gauge), determines the thickness of the internal copper conductors. A lower AWG number means a thicker wire, capable of handling more current over longer distances with less electrical resistance. Choosing the right gauge depends on your device’s power needs, the cable’s length and how flexible or rugged the cord needs to be. 

For heavy-duty or long-distance applications, 12 AWG cords are your best bet—they offer durability and top-end performance. 14 AWG cords are a dependable choice for general-purpose use with most office and networking gear. For lighter loads and greater flexibility, 18 AWG cords work well, especially in tight spaces or when mobility is a priority. 

Summary 

Keeping a supply of replacement power cords on hand is one of the easiest ways to reduce downtime and avoid compatibility headaches. It also gives you the opportunity to upgrade to higher-performing cables that better suit your setup’s power, length and environmental demands. With a solid understanding of configuration, plug type, power draw and wire gauge, you’ll be better equipped to make smart, informed purchases that keep your devices safe and running smoothly.
