🧭 Quick Start

1. Power off the PSU and disconnect it from the PC.

2. Plug the 20/24-pin ATX connector into the tester (and optionally CPU/GPU/SATA leads).

3. Turn on the PSU.

4. Listen & read:

   • Short “Du-Du” beep, no flashing → rails are within range.

   • Continuous long beep or flashing value/PG → missing or out-of-range rail; PSU likely faulty.

5. Power off and unplug before changing connectors.

🧠 Tips for Accurate Results

• Test one PSU at a time in a stable AC outlet.

• If a rail is borderline, retest with fewer leads connected.

• PG (Power-Good) should appear quickly (typ. 100–500 ms). Very slow/unstable PG can indicate PSU issues.

• This tool checks voltage presence & PG—it doesn’t load-test at full wattage.
