🧭 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 β€œDu-Du” beep, no flashing β†’ rails are within range.

    • Continuous long beep or flashing value/PG β†’ 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 & PGβ€”it doesn’t load-test at full wattage.
