SKU CH-BPA7-XY961

A 24-pin ATX bridging plug that lets a power supply run independently of a motherboard for system or water-cooling loop testing

  • Product typeAT
  • Powers a PSU without a motherboard using the 24-pin bridging plug
  • Tests power supplies on the bench before system assembly
  • Verifies water-cooling loops safely with the PSU running independently
  • Simplifies PSU fault-finding by isolating it from other components
  • Compact AT-type connector fits standard 24-pin sockets for quick checks

ATX PSU Bridging Plug for Bench Testing

This 24 pin ATX bridging connector lets you start a power supply without a motherboard attached. It is built for technicians and hobbyists who need to verify PSU output or circulate coolant in a custom loop before the rest of the system is assembled. The plug bridges the required pins so the unit powers on immediately when the mains switch is flipped. No additional wiring or adapters are required.

Suited for PSU and Loop Validation.

The connector is intended for temporary bench use such as checking voltages, running a pump during leak testing, or powering fans while routing cables. It is not designed to stay inside a closed case as a permanent replacement for the motherboard connection. Builders who need a long-term 24 pin extension or a right-angle adapter for tight clearance should look at a different product.

24 Pin ATX Form Factor Determines Compatibility

The plug matches the standard 24 pin ATX header found on most modern desktop power supplies. If your PSU uses a different pin arrangement the connector will not seat correctly and cannot bridge the power-on signal. Always confirm the header layout on your unit before purchasing.

Questions about this item

What does the 24-pin ATX connector actually do when I plug it into my power supply?

It bridges the required pins so the PSU turns on without a motherboard attached, letting you verify voltages or run pumps and fans.

Does this plug follow the standard ATX pin-out, or is it a proprietary layout?

It uses the regular 24-pin ATX pin-out, so it fits any standard desktop power supply.

Will the connector physically fit inside a cramped test bench or tight case cutout?

The plug has the same dimensions as a normal 24-pin cable end, so it occupies no more space than a motherboard socket would.
