Power Supply Bridge Barrow GJQD-24 V2 24-pin ATX connector adapter for PSU testing

Barrow GJQD-24 V2 is a 24-pin ATX bridge adapter designed to simplify power supply testing and troubleshooting. The adapter connects directly to standard 24-pin PC power supplies to allow bench testing, voltage measurements, and powering components without a motherboard. Its compact form factor and clear pin mapping make it suitable for fast diagnostic checks, routine maintenance, and safe bench use.

Advantages

The adapter provides a reliable direct connection for 24-pin ATX power supplies, enabling quick start-up and stable signal reference for voltage measurement. Its compact design reduces cable clutter on the bench and allows easy insertion and removal of the PSU connector. The device helps isolate PSU faults by powering the supply independently from the system, reducing the time needed to identify defective units.

Suitable for

• Bench testing of ATX power supplies
• Measuring +12V, +5V, +3.3V and standby rails with a multimeter
• Powering fans, pumps or other components temporarily without a motherboard
• Troubleshooting PC boot and power-related issues

Key specifications

• Connector type: 24-pin ATX male/female adapter compatible with standard ATX PSU connectors
• Function: Manual bridge/adapter for PSU activation and testing
• Form factor: Compact, bench-friendly adapter suitable for temporary connections
• Compatibility: Works with standard ATX power supplies designed for desktop computers
• Safety: Provides defined pin access for safe voltage measurement and identification of rails

How to use

Connect the adapter to the 24-pin ATX connector of the power supply while the PSU is powered off. Ensure all peripheral cables are disconnected from the PSU and the workspace is free from conductive debris. After connecting, switch on the power supply via its main switch or built-in power control. Use a multimeter or test equipment to probe the adapter’s accessible pins to measure voltages and verify rails. When testing is complete, switch the PSU off before disconnecting the adapter.

Recommendations

For safe and accurate testing, disconnect all system loads and peripheral devices before using the bridge adapter. Use insulated multimeter probes, observe correct polarity when measuring, and avoid touching exposed contacts while the PSU is powered. Use the adapter only for diagnostic and temporary powering tasks; do not use it as a permanent wiring solution.
