Compact ATX power supply tester
The myVolts tester checks 20-pin and 24-pin ATX connectors plus SATA, floppy and 4, 6 and 8-pin HDD power plugs. It is built for technicians and hobbyists who need a quick go/no-go verdict before installing a unit. A row of LEDs shows the status of each rail at a glance. No software or external power is required.
Rugged ABS body with direct plug-in sockets
The black ABS housing measures roughly 2.76 by 1.97 by 0.79 inches and fits in a tool bag. Every connector faces the same side so you can plug a supply in without hunting for orientation. The sockets accept standard ATX, SATA, floppy and peripheral power plugs directly, no adapters needed. It is a passive device that draws its test current from the supply under test.
Instant rail verification with LED indicators
Seven LEDs on the right report +3.3 V, -12 V, PG, +5 VSB, +12 V, -5 V and +5 V on the main connector. Separate left-hand LEDs cover +12 V and +5 V for HDD, +12 V for P4/P6/P8, +12 V and +5 V for floppy, and +12 V, +3.3 V and +5 V for SATA. All lights lit means the rail is present; a missing light flags a fault immediately. Not suited for builders who need load testing or ripple measurement.

Questions about this item
Does the 20/24-pin ATX connector test the PG signal and all seven voltage rails?
Yes, the 20/24-pin socket checks +3.3V, -12V, PG, +5VSB, +12V, -5V and +5V; all seven LEDs must light for a healthy supply.
What are the exact dimensions of the tester so I know it fits my tool drawer?
The rugged ABS body measures approximately 2.76 by 1.97 by 0.79 inches (7 by 5 by 2 cm).
In what order do I connect the different power leads to avoid missing a rail?
Test the 24-pin first, then HDD (+12V/+5V), then P4/P6/P8 (+12V), then floppy (+12V/+5V), and finally SATA (+12V/+3.3V/+5V).
