Power Supply Diagnostic Tester

The myVolts power supply tester provides a quick functional check for ATX, BTX and ITX units. It is designed for the ambitious hobby user and for trade specialists who need to verify a supply before installation. The device plugs directly into the 20 or 24 pin main connector and auxiliary power headers. An LCD shows the status of each voltage rail during the test.

Build Quality And Connector Coverage

The tester body is made from plastic and electronics in a black finish measuring 12 x 6.5 x 1.5 cm. It includes jacks for floppy, HDD, CDROM, SATA, 4 pin P4, 8 pin dual CPU and 6 pin PCI Express connectors. This range lets you check every major power cable from a single unit without swapping adapters. The robust construction suits repeated bench use.

Upgrade From Basic Paperclip Tests

This tester replaces the unreliable paperclip method and simple LED checkers that only confirm the supply turns on. It measures +12V, -12V, +5V, -5V, +3.3V, +5V standby and the power good signal, sounding a long buzzer when any rail is missing or out of range. The jump is worth it when you need to confirm every voltage before fitting a supply to a build.

Questions about this item

Does the tester read +12V, -12V, +5V, -5V, +3.3V, +5V SB and PG on a 20/24-pin ATX connector?

Yes, the LCD shows the status of +12V, -12V, +5V, -5V, +3.3V, +5V standby and PG when a 20/24-pin ATX connector is plugged in.

What space is needed to fit the 12 x 6.5 x 1.5 cm tester in a tool kit or on a bench?

The unit measures about 12 cm long, 6.5 cm wide and 1.5 cm thick, so it fits in a small tray or pocket.

How do I connect the 24-pin, P4, P6 and P8 cables and what step is often missed?

Plug each cable into its matching jack on the tester, then switch on the PSU; the step often missed is powering the supply after all connectors are seated.
