XH-M229 ATX Desktop Power Supply Module Price in Bangladesh

The XH-M229 ATX Desktop Power Supply Module is a compact breakout and distribution board designed to make the commonly available voltage rails of a compatible desktop ATX power supply easier to access. Instead of working directly with a bundle of PC power-supply wires, the module provides organized output connections for commonly used DC voltage rails.

The board is particularly useful for electronics laboratories, repair benches, DIY electronics projects, prototyping, and testing applications where a desktop ATX power supply is available as a source of regulated DC power.

The XH-M229 typically accepts a 24-pin ATX connector and exposes multiple voltage outputs, including +3.3V, +5V, +12V and -12V. Many versions also include screw-type or binding-post output terminals, a power switch, and an LED indicator.

Overview of XH-M229 ATX Power Supply Module

A standard desktop ATX power supply can provide several useful DC voltage rails, but its original cable harness is designed primarily for computer hardware. The XH-M229 provides a convenient interface for accessing these rails in a more organized way.

The module does not function as an independent AC-to-DC power supply. Instead, it acts as an interface between a compatible ATX power supply and the user’s electronics project. The actual voltage and current capability come from the connected ATX PSU.

Depending on the board revision, the available output groups may include +3.3V, +5V, +12V, -12V and ground. The output arrangement can differ slightly between manufacturers, so the labels printed on the specific board should always be followed.

What Is an ATX Power Supply Breakout Board?

An ATX power supply breakout board is an interface PCB that converts the multi-wire output of a desktop computer PSU into easily accessible terminals.

A conventional ATX PSU already provides several regulated DC rails. A breakout board simply provides a convenient way to access those rails without having to modify or manually splice the PSU cable harness.

The XH-M229 is therefore useful as a practical bench-power interface for projects that need common PC power-supply voltages.

Technical Specifications

The commonly listed physical size is approximately 128 × 48 × 30 mm, although dimensions and terminal arrangements can vary between board revisions.

Working Principle

The XH-M229 receives power from the output connector of a compatible desktop ATX power supply. The ATX PSU provides its regulated DC rails through the main connector.

The breakout board routes the appropriate voltage rails to clearly identified output terminals. This allows the user to connect compatible electronic circuits without directly working with the original ATX cable bundle.

For example, the +5V and GND terminals can provide access to the PSU’s 5V rail, while +12V and GND provide access to the 12V rail. The +3.3V rail is also made available for circuits that require that voltage.

Some XH-M229 versions additionally expose the -12V rail. This rail is intended for applications compatible with the ATX PSU’s -12V specification and should not be treated as a high-current output. The actual current capability of every rail is determined by the connected ATX power supply rather than by the breakout PCB alone.

Applications

The XH-M229 is useful for a variety of electronics and computer-related applications, including:

• Electronics laboratory bench power
• Arduino and microcontroller projects
• Raspberry Pi-related testing
• DC motor and electronics experiments
• LED and lighting projects
• Computer repair and testing
• Electronics troubleshooting
• DIY power-supply projects
• PCB testing
• Embedded-system development
• Robotics prototyping
• Audio electronics experiments
• Educational electronics laboratories
• Component testing
• Providing multiple DC rails for prototypes

Advantages

The biggest advantage of the XH-M229 is convenience. A standard ATX PSU can provide several regulated voltage rails, but accessing those rails directly from the original wiring harness can be inconvenient during prototyping.

The XH-M229 organizes the available outputs into labeled terminals, making it easier to connect test circuits and development boards.

The onboard switch also provides convenient control of the connected ATX PSU on compatible configurations, while the LED indicator provides a quick visual indication of the module’s power state.

Because the module does not generate the primary DC rails itself, users can take advantage of an existing compatible ATX PSU without purchasing a separate multi-output bench supply.

Limitations

The XH-M229 is an interface and breakout module, not an independent AC mains power supply. It requires a compatible ATX PSU to provide the actual electrical power.

The maximum current available from each output is determined by the connected ATX power supply and its individual rail ratings. The breakout board should not be assumed to increase the PSU’s current capability.

Different XH-M229 versions can also differ in fuse arrangements, terminal styles, dimensions, and available outputs. Always check the markings on the actual module before connecting a load.

Installation and Usage Tips

Use the XH-M229 only with a compatible ATX power supply and verify the connector orientation before connecting the PSU to the board.

Check the voltage label of the desired output before connecting any electronic circuit. A circuit designed for 5V should not be connected to the 12V terminal.

Keep the load within the current capability of the corresponding ATX PSU rail. The module distributes the PSU’s available power; it does not increase the PSU’s rated output.

Before making or changing wiring, switch the system off and disconnect the appropriate power source. Avoid short circuits between output terminals or between a voltage rail and ground.

For laboratory or educational use, clearly label connected circuits and verify polarity and voltage with an appropriate meter before powering sensitive electronics.

Why Choose XH-M229 ATX Desktop Power Supply Module?

The XH-M229 is a practical choice for users who already have a compatible desktop ATX power supply and want a cleaner way to use its DC outputs for electronics projects.

Its multiple output rails, organized terminals, compact design, power switch, and indicator make it suitable for electronics benches, educational laboratories, repair work, and DIY prototyping.

Rather than modifying the original PSU wiring, users can use a dedicated breakout interface to access commonly available ATX voltage rails.
