20/24 Pin PSU Tester for Desktop Builders

This tool checks ATX power supplies by lighting LEDs for the 12 V, 5 V and 3.3 V rails. It connects to the main 20/24 pin connector and to SATA power plugs. The device is new and intended for quick go/no-go verification before a system is assembled.

Voltage Rail Indication Only

The tester shows whether each rail is present but does not measure exact voltage values or load capacity. Builders who need precise readings or ripple analysis will require a multimeter or an oscilloscope instead.
