This 5V 10A Switching Power Supply delivers up to 50W of stable DC power, making it ideal for driving LED strips, motors, CNC projects, and other power-hungry 5V devices. It accepts both 110V and 220V AC input, so it works worldwide with the appropriate mains cable.
The output connects via a standard 2.1mm DC barrel jack, and a green LED indicator confirms the supply is active. Compared to modifying an ATX power supply, this dedicated unit is smaller, quieter, and ready to use out of the box.
Key Features
- Output – 5V DC at up to 10A (50W)
- Input – 110V or 220V AC (universal)
- Connector – 2.1mm DC barrel jack output
- LED Indicator – Green power status LED
- Compact Design – Smaller and quieter than an ATX supply
Ideal For
- Powering 5V addressable LED strips (WS2812B, NeoPixel, etc.)
- CNC machines and multi-motor projects
- Large microcontroller or Raspberry Pi installations
- Any project requiring a dedicated high-current 5V supply
Package Contents
- 1× 5V 10A Switching Power Supply
- 1× US mains cable
Jargon buster
Plain-language definitions for the technical terms used above.
- DC barrel jack
- A round power connector commonly used for low-voltage DC power supplies, often described by its outer and inner diameters such as 5.5 x 2.1 mm. Matching the barrel size and polarity is important so the plug physically fits and powers the device correctly.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- NeoPixel
- A type of addressable LED system where colour data is sent along a single digital data line from one LED or controller to the next. Compatibility matters because the timing and signal format must match for the lights or driver board to respond correctly.
