20/24 Pin ATX Power Adapter Board with Acrylic Case

Transform any standard computer ATX power supply into a versatile bench power supply board with this DC-DC adapter board. It compatible with all 20-pin and 24-pin PSUs, it outputs +12V, -12V, +5V, 5VSB, and 3.3V via high-current wiring terminals. Features a digital voltage display for real-time monitoring, toggle switch for easy operation, USB fast charging (QC2.0/QC3.0), and Type-C PD2.0/PD3.0 support. Perfect for electronics labs, DIY projects, device testing, and powering mobile devices.

How to Use with an ATX Power Supply:

• Prepare the PSU: Ensure the ATX power supply is unplugged.
• Connect 20/24-pin connector: Plug the PSU's motherboard cable into the adapter board.
• Connect peripherals (optional): Connect PSU's CPU/EPS or PCIe cables if additional power is needed (for high-current loads).
• Set toggle switch to OFF.
• Connect AC power to the PSU.
• Flip toggle switch ON – the PSU powers up, digital display illuminates.
• Connect your devices to terminals, USB ports, or Type-C port.
• Monitor voltage on the digital display.

How to Use with DC Input (No ATX PSU):

• Supply DC12V-24V to the DC mother socket (barrel jack).
• Fast charging USB and Type-C ports will function.
• Terminal outputs may not function (requires ATX PSU for -12V, 5VSB, etc. – check board design).

Safety Notes:

• Do not exceed PSU rated current – respect the power supply's specifications
• Provide adequate ventilation – ATX PSUs need airflow when under load
• Use appropriate wire gauge for terminal connections based on expected current
• Keep away from moisture – this is an indoor, dry-location board
• Add a fuse between PSU and your load for protection (recommended)
