Can You Power a Monitor without a Power Cord?

When setting up your computer, there are many things to consider, from the PCU to the monitor. You also need many cables to connect the various components – but can you power a monitor without a power cord?

It’s only possible to power a monitor with a power cord. Although the connective ports and cables carry voltage, the monitor requires sufficient power from its cable to turn on its backlight and provide the picture on the screen.

Read on to find out why a power cord is necessary for your computer monitor and what you need to know if you’re planning to build your computer system.

What is a Monitor Power Cord?

Sometimes referred to as a mains or flex cable, a power cord is a primary cable that connects your computer’s monitor to a power source. All hardware comes with a power cord, including printers and other PC components.

Helpfully, most monitors come with a functioning power cord, meaning it’s easy to connect your device to power, and you don’t necessarily need to worry about ordering the most appropriate cable for your device.

Some people assume that a monitor only requires a data cable (the cable that connects the monitor to the PC), but the reality is that a power cord is essential, as we explain below.

What Cables Does a Monitor Need?

Every PC monitor requires at least two cables: a power cable and a data cable. As the name suggests, the power cable connects the monitor to a power outlet and enables you to turn on your monitor.

Are Monitor Power Cords Universal?

When looking for the best way to connect your monitor to a power source, the good news is that monitor power cables are universal, meaning you can easily pick up a monitor power cord online that will be a perfect fit for your device.

Therefore, you risk damaging your computer’s screen if you connect your monitor with the wrong power adaptor.

Power adaptors connect laptop computers to power, so you must be careful when ordering a replacement adaptor for your device. You should always check the voltage and outputs before ordering the most suitable adaptor for your computer.

Where to Find a Replacement Power Cord?

Because monitor power cords are universal, you won’t have issues finding a replacement cable for your device. A quick Google search will reveal a whole host of options, and you can order from an online store you’re comfortable with.

As with many tech items, Amazon is a great place to start, but you can also look at specialist computer stores and platforms if you prefer.
