24-Pin ATX Power Supply Jumper Tool

This jumper tool powers on ATX power supplies without a motherboard connection, making it essential for testing PSUs before installation, running bench setups, or powering standalone 12V devices. Simply plug the 24-pin connector into your power supply and switch it on—the jumper bridges the PS_ON signal to ground, exactly as a motherboard would.

Works with both 20-pin and 24-pin ATX power supplies. Built with proper 18 AWG wire to ensure reliable contact with the crimp pins. Common applications include testing new or suspect power supplies, powering GPU test benches, running 12V appliances like car audio equipment, or keeping a secondary PSU active in dual-PSU mining or workstation configurations.
