Diagnostic tool for desktop PSU inspection

This digital LCD power supply tester is built for technicians and DIY enthusiasts who need to verify ATX and BTX units quickly. It reads core output voltages including 3.3V, 5V, 12V, -12V and 5VSB in real time. The device helps identify faulty supplies before they damage motherboards, hard drives or graphics cards. It is not for buyers who want to test server-grade redundant power modules.

Plug-and-play operation with on-screen alerts

The compact tester requires no driver, external power source or installation; simply connect each cable to its matching socket. An integrated warning function flags overvoltage, undervoltage or unstable output as soon as it occurs. The high-resolution LCD presents every reading at a glance for rapid pass-or-fail decisions. It is not for users who need logged data export or automated test scripting.

Broad connector coverage for mainstream builds

Included interfaces cover 20/24-pin mainboard, SATA, PCI-E, 4-pin CPU and floppy drive power ports. This range lets a single tool validate the complete loom of a standard desktop power supply. The lightweight integrated housing makes it practical for bench work, repair shops or on-site troubleshooting. It is not for builders who require proprietary server backplane connectors.

Questions about this item

How do I connect the 20/24 pin motherboard cable to start testing?

Align the 20 or 24 pin plug with the matching socket on the tester and press firmly until it seats; the LCD powers on automatically and shows 3.3V, 5V, 12V and other rails.

What parts of this tester wear out and need replacing?

The spring contacts inside the 20/24 pin, SATA, PCI-E and 4 pin CPU sockets can lose tension after hundreds of insertions, so the whole unit is typically replaced when readings become erratic.

How long can I leave a supply under load before the tester overheats?

The tester has no internal cooling and is designed for short diagnostic checks; extended load testing will cause its own circuitry to overheat first.
