What is a desktop power supply?

A desktop supply is a PSU specifically designed to be used by small items or applications, like laptops, CCTV cameras or chargers. Due to the output of the PSU itself, they wouldn't be a suitable source for high tech desktops. A PC power supply is created specifically to be used with that computer, whereas these units can be interchanged, providing the technical specifications of the appliance meet the PSU's in terms of safety and usability.

Are these units only a laptop power supply?

The main purpose of a desk supply is predominantly for laptops. However, providing the appliance or item will accept the output electrical specifications and connector type, you could use this module in any of the following applications:
• Speakers
• Chargers
• CCTV Cameras
• Lamps and Lights

Note

The power supply is supplied without a power cable, please see essential accessory for a selection of compatible leads. Please make sure the device is able to support the power from this adaptor for both operational and safety reasons.
