Power supply tester for ATX and BTX units

This digital LCD tester checks desktop and server power supplies with 20+4 pin, SATA, and 8 pin CPU connectors. It displays voltage status on the built-in screen without requiring batteries. The tool is intended for hobbyists and technicians who need a quick functional verification.

Tests standard ATX, BTX, and ITX rails only

The unit monitors +3.3V, +5V, +12V, -12V, -5V, and +5VSB lines through its fixed connectors. It cannot measure load capacity, ripple, or efficiency, and it does not support proprietary or server-specific pinouts beyond the listed interfaces. Input voltage is rated for 220v mains supply.

Plug in the 24 pin and CPU cables to begin

Operation starts by connecting the supply's 24 pin and 8 pin cables to the corresponding jacks on the tester. No software or external power is required. The main limitation is that the device only indicates presence and approximate level of each rail, not stability under load.

Questions about this item

Should I pick the 20-pin or 24-pin version for my ATX supply?

The tester uses a combined 20+4 pin connector so it fits both 20-pin and 24-pin ATX power supplies without needing a separate adapter.

What does the LCD actually show when the unit is running?

The LCD displays the voltage status for each rail including +3.3V, +5V, +12V, -12V, -5V and +5VSB so you can verify each output is within tolerance.

Does the SATA connector on the tester limit the voltages I can check?

The SATA connector is an additional test point; the unit still monitors all standard ATX rails through the 20+4 pin and 8-pin CPU connectors so no voltage reading is capped by the SATA interface.
