With a USB-C monitor, you can connect your device and start working in seconds, without the need for a separate power cord.

How USB-C Monitors Receive Power

So, how do USB-C monitors receive power? The answer lies in the USB-C connector itself. USB-C is capable of delivering up to 100 watts of power, which is more than enough to power a typical monitor. When you connect a USB-C monitor to a device, the device sends power through the USB-C cable, which is then received by the monitor.

However, not all devices are capable of delivering 100 watts of power through USB-C. Some devices, such as laptops, may only be able to deliver 60 watts or less. This is where things can get a little complicated.

Power Delivery (PD) and USB-C Monitors

To ensure that USB-C monitors receive the power they need, manufacturers use a technology called Power Delivery (PD). PD is a fast-charging protocol that allows devices to negotiate the amount of power they need, up to 100 watts.

When a USB-C monitor is connected to a device, the device sends a request for power to the monitor. The monitor then responds with its power requirements, and the device adjusts its power output accordingly. This ensures that the monitor receives the power it needs to function properly.

Do USB-C Monitors Need a Power Supply?

Now that we understand how USB-C monitors receive power, let’s answer the question: do they need a power supply? The answer is not a simple yes or no.

If your device is capable of delivering enough power to your USB-C monitor, then you don’t need a separate power supply. For example, if you have a laptop that can deliver 60 watts of power through USB-C, and your monitor only requires 40 watts, then you’re good to go.

However, if your device can’t deliver enough power to your monitor, then you may need a separate power supply. This is often the case with larger monitors or those that require more power to function.

Device Power Output Monitor Power Requirements Needs Separate Power Supply?
60 watts 40 watts No
60 watts 80 watts Yes

When to Use a Separate Power Supply

So, when should you use a separate power supply with your USB-C monitor? Here are a few scenarios:

  • Your device can’t deliver enough power to your monitor.
  • You’re using a larger monitor that requires more power.
  • You’re using a monitor with high-power features, such as HDR or high refresh rates.

In these cases, a separate power supply can ensure that your monitor receives the power it needs to function properly.

Choosing the Right Power Supply

If you need a separate power supply for your USB-C monitor, it’s essential to choose the right one. Here are a few things to consider:

  • Power output: Make sure the power supply can deliver enough power to your monitor. Check the monitor’s specifications to determine its power requirements.
