Fervit 20/24 Pin ATX Benchtop Breakout Adapter 4 Channel 3.3V 5V 12V -12V 5A Fuse Green

SKU CH-PS2Q-CXSP6

Turns a PC power supply into a benchtop unit with 3.3V, 5V, 12V and -12V outputs, each fused at 5 A and accessed via binding posts

  • Turns an ATX supply into a four-channel benchtop unit
  • Delivers 3.3 V, 5 V, 12 V and -12 V for embedded work
  • Each channel protected by a replaceable 5 A fuse
  • Binding-post grounds give quick, secure connections
  • Built-in power switch and indicator simplify bench testing

Benchtop ATX Breakout Adapter

The Fervit 20/24 pin ATX breakout adapter converts a standard computer power supply into a benchtop unit for embedded electronics development. It exposes four regulated voltage rails through binding posts with integrated ground connections. A built‑in power switch and indicator LED provide direct control during prototyping. Plastic spacers on the PCB help prevent accidental short circuits on the workbench.

4 Channel Voltage Outputs

The adapter delivers 3.3V, 5V, 12V and -12V channels from the ATX source, matching the typical rails required by microcontroller boards, sensors and analogue circuits. Each channel is protected by a replaceable 5A fuse, so a fault on one rail does not disable the others. The on‑board 24 pin connector accepts both 20 and 24 pin ATX plugs for broad PSU compatibility.

Sustained Load Behaviour

Under continuous draw the replaceable 5A fuses on every channel limit current to protect the host power supply and the adapter PCB. The binding‑post terminals maintain a secure connection during long test sessions without the vibration‑induced loosening common with spring clips. The plastic spacer design keeps the board elevated, improving airflow and reducing thermal stress during extended operation.

Questions about this item

What voltages can I draw from the 20/24 pin ATX breakout for my bench projects?

The adapter provides four regulated outputs — 3.3V, 5V, 12V and -12V — each with its own binding post and shared ground posts for easy wiring.

How does the on-board 24-pin ATX connector limit the power I can pull from each rail?

Each channel is protected by a replaceable 5A fuse, so continuous draw per rail is capped at 5 amps before the fuse opens.

What physical spacing does the board use to prevent shorts when mounted on a bench?

The PCB includes built-in plastic spacers that raise the board off the work surface, keeping solder joints and traces clear of conductive debris.
