Choosing the Right Monitor Power Cord

Monitor power cords are not interchangeable. The plug that enters the monitor is an IEC connector, and the inlet type decides which cord fits. Desktops and many monitors use the IEC 60320 C13 connector, some monitors and laptop bricks use the C5 cloverleaf, and slim power supplies use the C7 figure-8 inlet. This guide explains each type and how to specify a safe replacement.

Quick Answer / Summary

Check the inlet on the device, not the wall plug. Desktop monitors most often use an IEC 60320 C13 cord, while the C5 cloverleaf suits many laptop bricks and some monitors, and the C7 figure-8 inlet fits slim power supplies. Match the cord gauge to the device current draw, keep the length reasonable, and prefer cords with a UL listing for safety.

The IEC 60320 C13 Cord

The C13 connector has three rectangular pins in a block with a notch, and it plugs into the C14 inlet found on most desktops and many monitors. This is the familiar three-conductor cord used with power distribution units and desktop towers.

Because the C13 is common, a spare is easy to find. Buy one that matches the current rating stamped on the device and the certification marks printed on the jacket.

Gauge and Current Rating

Cord gauge describes how much current the conductors carry safely. Thicker conductors, given as a lower gauge number, carry more current. Always match or exceed the rating of the device rather than using a lighter cord from a different appliance.

The C5 Cloverleaf Cord

The C5 connector is a three-pin plug whose pins form a small triangle inside a shield, so it is often called a cloverleaf. Many laptop power bricks and some monitors use the matching C6 inlet.

The C5 shape makes the plug orientation obvious and keeps the cord seated under light tension. Keep a spare in the bag when you travel with a brick that uses this inlet.

C5 Versus C13

Both are three-conductor cords, but the connectors differ in shape and cannot be forced together. Identify the inlet by drawing its outline on paper, then compare it with the cord you plan to order.

The C7 Figure-8 Cord

The C7 connector has two round pins in a figure-8 outline and uses only two conductors, so it carries no separate ground. Slim power supplies and some monitors use the matching C8 inlet.

Because there is no ground pin, use a C7 cord only on a device designed for it. Never modify a grounded cord to fit a two-pin inlet.

Specifying a Safe Replacement

Note the inlet type, the voltage and current rating, and the cord length you need. Then choose a cord with the correct gauge and a recognized certification mark such as a UL listing. Avoid cords that feel warm in use, and replace any cord with cracked or frayed insulation.

For a fleet, standardize on one cord type where possible, and label spares by inlet so a technician grabs the right part quickly.

Wall Plugs and Regional Variation

The wall end of a monitor cord depends on the country, not the monitor. The same C13 appliance end can come with a US, UK, or EU wall plug. Order by both ends: inlet type and wall plug type.

Never cut a molded wall plug to rewire a cord. A molded plug keeps its strain relief and its certification, and a field repair removes both.

Frequently Asked Questions

What power cord does a monitor use?

Most desktop monitors use an IEC 60320 C13 cord. Some monitors and laptop bricks use a C5 cloverleaf, and slim power supplies use a C7 figure-8 cord.

Are C13 and C5 cords interchangeable?

No. Both are three-conductor cords, but the connector shapes differ, so a C13 cord will not fit a C6 inlet and a C5 cord will not fit a C14 inlet.

Is a figure-8 cord grounded?

No. A C7 figure-8 cord uses two conductors and carries no ground, so use it only on devices designed for a two-pin inlet.

How do I choose the right cord gauge?

Match the gauge to the device current draw and never go lighter. A lower gauge number means thicker conductors that carry more current safely.
