ATX 20/24-Pin Power Adapter Board – LED Voltage Display Module
ATX 20/24-Pin Power Adapter Board – LED Voltage Display Module
ATX 20/24-Pin Power Adapter Board with Adjustable Voltage & LED Digital Display
Transform any standard ATX computer power supply into a versatile, multi-output bench power station. The diymore ATX 20/24-Pin Power Adapter Board features a real-time LED digital voltage display, high-current terminals, and a wide array of output interfaces — making it the ideal power module for electronics prototyping, device charging, and DIY lab setups. Made in Mainland China.
Key Features
- Universal ATX Compatibility: Works with all standard 20-pin and 24-pin ATX computer power supplies — no modifications needed.
- Multiple Voltage Outputs: Simultaneously delivers +12V, -12V, +5V, 5VSB, and 3.3V across clearly labeled terminals for maximum flexibility.
- LED Digital Voltage Display: On-board real-time voltage monitoring so you always know your exact output at a glance.
- Toggle Switch Control: Convenient on/off toggle switch for quick, reliable power management.
- Microcontroller-Ready IO Port: Built-in XH2.54-2P terminal header allows external 5V microcontroller or switch control of ATX power on/off — perfect for custom enclosures and automation projects.
- High-Current Terminals: Engineered with robust, high-current terminal blocks to ensure secure, reliable connections — no loose wiring.

3 USB Charging Outputs:
- 2× Standard USB ports: DC 5V, up to 2.1A each
- 1× Fast-Charge USB port: 5V–12V auto-adjusted, 2A (supports multiple fast-charge protocols)
- USB Type-C Output: Supports PD 2.0 / PD 3.0 protocols; outputs 5V or 9V at 2A — charge modern smartphones and tablets at full speed.
- DC Female Connector: Functions as both input (DC 12V–24V) and output (12V), enabling use as a standalone power supply without an ATX source.
- Low Power Consumption: Efficient design minimizes standby draw.

Frequently Asked Questions
Q: Is this ATX power adapter board compatible with both 20-pin and 24-pin power supplies?
A: Yes! The adapter board is fully compatible with all standard 20-pin and 24-pin ATX computer power supplies, making it versatile for a wide range of desktop PSU brands and models.
Q: Can I use the DC female connector as an input if I don't have an ATX power supply?
A: Absolutely. The DC female connector supports input voltages from DC 12V to 24V, allowing you to use the board as a standalone multi-output power module without an ATX PSU. In output mode, it delivers 12V DC.
Q: Does the Type-C port support fast charging for modern smartphones and tablets?
A: Yes. The Type-C interface supports PD 2.0 and PD 3.0 protocols, delivering 5V or 9V at up to 2A — compatible with fast charging on most modern USB-C smartphones and tablets (requires a PD-compatible cable and device).
Q: What does the XH2.54-2P terminal on the board do?
A: This reserved terminal allows you to connect the ATX power supply's on/off control to a microcontroller IO port (5V logic) or an external switch. It's especially useful for custom enclosure builds or automated setups where remote power control is needed.
Q: What is the difference between Kit I and Kit II (Set Two)?
A: Kit I includes the adapter board only. Kit II (Set Two) bundles the adapter board with a clear acrylic protective shell and mounting accessories, offering better physical protection and a cleaner look for your workbench setup.
