myVolts ATX 24/20 Pin Breakout Board with USB 5V Port and Acrylic Base

SKU CH-JABP-WRXFQ

ATX breakout board converts a 24-pin supply into 3.3V, 5V, 12V and -12V terminals plus a USB 5V port with power switch and indicator LEDs

  • TypeAT
  • Converts ATX supply into bench power
  • Supports 20, 20+4 and 24 pin connectors
  • Terminal blocks output 3.3V, 5V, 12V and -12V
  • Built-in power switch with standby and power-on LEDs
  • Compact 100 by 60 by 16 mm acrylic base

Benchtop Power for Embedded Projects

This breakout board converts a standard ATX power supply into a bench-top source for embedded electronics development. It accepts 20, 20+4 or 24 pin ATX connectors and provides terminal blocks for 3.3V, 5V, 12V and -12V rails. An on-board power switch and indicator LEDs give direct control over the output. The acrylic base keeps the module stable on a workbench.

Replaces Loose Wiring and Adapters

The board removes the need for custom harnesses or paper-clip jumpers when powering prototype hardware. It is worth the switch when a project needs reliable access to multiple ATX voltages at once. Builders who only need a single fixed rail or who prefer a dedicated laboratory supply will not benefit from this approach.

Fits Into a Prototype Workflow

The module measures 100 by 60 by 16 millimetres and mounts on its acrylic base. It connects to the ATX supply via the standard 24 pin connector and breaks out power through screw terminals. A USB 5V port and three 2.54 millimetre two-pin cables are included for convenient low-voltage distribution. No additional mounting hardware is required.

Questions sur cet article

What clearance does the 100 mm by 60 mm acrylic base need on a bench?

The board measures 100 mm long, 60 mm wide and 16 mm high, so allow at least that footprint plus room for the ATX cable and terminal-block wiring.

Which step do users skip when connecting a 20+4 pin ATX supply to the 24 pin on-board connector?

Fully seat the 24-pin plug until the latch clicks, then use the on-board power switch to turn the supply on; the stand-by and power-on LEDs confirm it is live.

When should the 2.54 mm 2-pin cables supplied with the board be replaced?

Replace them if the insulation cracks, pins loosen or you need longer leads for a different bench layout.
