Compact PSU Tester

The myVolts ATX power supply tester connects to a 20 or 24 pin connector and reads 3.3V, +5V, +12V, -12V and +5VSB rails plus the PG signal on its LCD. It is built for technicians and builders who need a quick pass-or-fail check on ATX, BTX, ITX or TFX units without a multimeter.

Silent Passive Operation

The aluminium alloy body dissipates heat without a fan so the tester adds no noise to the bench. Power is drawn directly from the supply under test, so there is no separate adapter or battery to manage during a session.

Bench Ready Connections

The unit accepts 20 pin, 24 pin, 4 pin, 8 pin, 6 pin PCIe, SATA, floppy and Xeco plugs so one tool covers every output. Only the main ATX connector drives the LCD readout; peripheral sockets show status through LED indicators.

Questions about this item

How do I install the myVolts ATX power supply tester and what step do people often miss?

Plug the 20 or 24 pin ATX connector into the tester; the LCD only activates when that main connector is seated — auxiliary SATA, P4, P6 or P8 plugs only light LEDs and will not show voltages on screen.

What maintenance or replacement will the myVolts tester need over time?

The aluminium alloy body has no user-serviceable parts; if the internal buzzer or LCD fails the whole unit must be replaced, as no calibration or component swap is supported.

What limit appears first when the myVolts tester runs continuously under load?

Extended use can overheat the compact aluminium housing because there is no active cooling; allow cool-down periods during long test sessions to avoid thermal shutdown.
