ATX BTX ITX power supply tester

The myVolts power supply tester checks ATX BTX and ITX compliant units with a built-in LCD that displays voltage status. It is designed for hobbyists who want a quick functional check and for trade professionals who need a rapid diagnostic tool. The compact black plastic body measures about 12 by 6.5 by 1.5 centimetres. No external power source is required because the tester draws supply from the unit under test.

Check your power supply connectors before ordering

Verify that the power supply you intend to test provides a 20 or 24 pin ATX connector plus the necessary 4 pin P4 6 pin PCI-Express or 8 pin dual-CPU plugs. The tester also accepts floppy HDD CDROM and SATA peripheral connectors for load testing. If your power supply lacks any of these interfaces the corresponding voltage rails cannot be evaluated. Ensure the power supply is disconnected from the motherboard before plugging it into the tester.

LCD display and audible alarm simplify fault finding

The LCD shows real-time readings for plus 12V minus 12V plus 5V minus 5V plus 3.3V plus 5V standby and the 12V power good signal. A short beep at power-on indicates normal output while a continuous buzzer sounds when a voltage is missing or outside limits. The corresponding voltage value or PG indicator will also flicker on the screen. This immediate feedback lets you confirm a healthy supply or identify a failed rail without additional instruments.

Questions about this item

Does the myVolts power supply tester ship with any cables or adapters, or must they be purchased separately?

The package contains only the tester unit itself. All required connectors — 20/24-pin ATX, 4-pin P4, 8-pin dual-CPU, 6-pin PCIe, SATA, floppy and HDD/CDROM — are built into the device, so no extra cables are needed.

The description lists ATX, BTX and ITX compliance; which version should I choose for a modern ATX build?

This is a single model that covers ATX, BTX and ITX power supplies. For a current ATX system you simply plug the 24-pin and 4-pin or 8-pin CPU connectors into the matching jacks on the same unit.

What do the +12 V, +5 V and +3.3 V readings on the LCD tell me when the tester is connected to a live PSU?

The display shows real-time voltage levels for each rail. If a rail is missing or outside normal tolerance the tester sounds a continuous buzzer and the corresponding voltage value or PG indicator flashes, signalling a faulty supply.
