myVolts ATX Power Supply Tester

The myVolts ATX Power Supply Tester is a diagnostic tool for checking computer power units. It connects directly to 24-pin and 20-pin motherboard connectors as well as peripheral leads. LED indicators show the presence of voltage on each rail. The unit is built from ABS plastic and requires no external power source.

Technicians and builders verifying PSU health

This tester suits anyone who needs to confirm that a power supply delivers correct voltages before installing it in a system. It is not for users who want to measure exact voltage values or ripple under load. Buyers needing automated logging or software reporting should look at a different class of instrument.

Tests 24 20 12 3.3 SATA rails

The single specification that decides fit is the range of connectors and voltage rails covered. The device checks the main 24-pin and 20-pin ATX connectors plus P4, P6, P8, floppy and SATA power leads. It verifies the 12 V, 5 V, 3.3 V, -12 V, -5 V and 5 VSB rails plus the Power Good signal. If your power supply uses only these standard connectors, this tester will confirm basic function.

Questions about this item

Which main power connectors does the tester accept for the 24-pin and 20-pin ATX plugs?

The unit provides a combined 24P (20P) socket that fits both the 24-pin and 20-pin ATX power connectors from the supply under test.

What is the correct sequence for checking the SATA power output after testing the main ATX connector?

After the main ATX test, disconnect any HDD or P4 connectors, then insert the SATA power plug into the tester's SATA socket and verify the +12 V, +3.3 V and +5 V indicators light up.

Are there any user-replaceable parts or calibration requirements for this tester over time?

The tester has no user-replaceable components and requires no periodic calibration; it is a passive LED indicator device with no internal batteries or firmware.
