  • Tests ATX, SATA and HDD connectors to verify power delivery

Compact ATX Power Supply Tester

The myVolts tester is a pocket-sized diagnostic tool for desktop power supplies. It plugs directly into 20-pin or 24-pin ATX connectors as well as SATA and HDD power leads. A green LED confirms when voltage rails are present. Rugged ABS plastic housing protects the internals during bench use.

Suits quick rail checks, not deep analysis

Ideal for technicians who need a fast pass-or-fail indication on +3.3 V, +5 V, +12 V, -12 V, -5 V and +5 VSB rails. Builders wanting detailed ripple, efficiency or load-regulation data should use a multimeter or programmable load instead. The unit does not store results or interface with software.

No accessories change the workflow

The package contains only the tester itself. No cables, adapters or software are bundled, so every connection must come from the power supply under test. The seven right-side LEDs and two left-side HDD LEDs give immediate visual feedback without any extra equipment.

Questions about this item

What power-supply connector must I have on my PSU to plug into the 20/24-pin socket on this tester?

Your power supply needs a standard 20-pin or 24-pin ATX main connector to mate with the tester's 20/24-pin socket.

Will the tester still light its LEDs if I connect an older PSU that lacks the -5 V rail?

The -5 V LED will stay off on such a unit; the remaining six right-side LEDs (+3.3 V, -12 V, PG, +5 VSB, +12 V, +5 V) should still illuminate if those rails are present.

After plugging in the 24-pin and SATA connectors, which LEDs confirm the tester itself is working?

All seven right-side LEDs (+3.3 V, -12 V, PG, +5 VSB, +12 V, -5 V, +5 V) plus the two left-side LEDs (+12 V, +5 V) should be lit when the PSU is powered on.
