ATX Power Supply Tester 20 24 Pin

This new myVolts tester checks ATX, BTX, ITX and TFX power supplies. It connects to the main ATX connector and reads 3.3V, +5V, +12V, -12V and +5VSB rails plus the Power Good signal. An LCD shows each voltage and PG value while a buzzer warns when any reading falls outside the normal range.

For DIY builders and repair technicians

Suits anyone who needs a quick go/no-go verdict on a desktop PSU before fitting it to a motherboard. Not for users who require load testing under real current draw, automated logging, or validation of server-grade redundant units.

Voltage rails measured 3.3 5 12 -12 5VSB PG

The single specification that decides fit is the set of rails the device can read. This unit reports 3.3V, +5V, +12V, -12V, +5VSB and PG. If your workflow demands additional rails such as -5V or separate +12V1 and +12V2 monitoring, this tester will not meet that need.
