Computer PC Power Supply Tester, ATX/ITX/IDE/HDD/SATA/BYI Connectors Power Supply Tester, 1.8'' LCD Screen (Aluminum Alloy Enclosure)

Worked as expected and the screen was clear and easy to read. Reading 9n my power supply was accurate and helped em easily diagnose my issue. Not a bad price either

Excellent piece of kit. Got tired of guessing if a no-boot problem was the PSU, the case, or something else. After shorting the power switch on the mobo, this simple and cheap gadget saves me from having to swap PSUs.

A PSU tester is a useful, inexpensive “first-pass” tool. It’s great for basic checks: dead PSUs, obviously faulty units, or ensuring rails nominally output correct voltages before building a PC. Pros: Safe and easy to use Affordable & handy for basic diagnostics Cons: Only tests idle output, not under-load behavior No check for power quality

Good: Works as expected. Was able to detect a newly bought PSU’s voltage failure. Saved my time and energy. Worth the money. Bad: As the other review mentioned, the molex and sata port cutout is sharp and I had to sacrifice some drops of blood. You want to be careful or wear a glove if you need to grab it to add force. The 20/24 pin mobo plug is too tight. There is no latch as well, so you cannot plug your mobo cable firmly. It works with half-way plugged in.

Does what you need it to do for a PC power failure diagnostic. Don't replace components on your PC until you use a device like this

Works great, checked all the sketchy PSU's I bought and it told me exactly what i need to know.

This PSU tester is a fantastic tool for diagnosing power supply issues! The 24-pin connector is a snug fit, but it works perfectly once connected. The instructions included were thorough, written clearly in English, and made the process of plugging everything in straightforward. I really appreciated the beeps that let me know when it was ready for the 4p, 6p, and 8p connectors (didn’t try Molex or SATA, but I’m sure they’d work just as well). It helped me confirm a failed power supply—just keep in mind that the tester is powered by the 24-pin, so if the PSU is completely dead, the tester won’t light up. I tested it with a second PSU, and the device worked perfectly, showing accurate voltages. The only downside is that it didn’t include instructions for unplugging, but that’s minor and doesn’t affect its performance. Highly recommend this tool for anyone troubleshooting PC power issues!

This tester is largely designed for testing voltage on ports and cables, and maybe finding a bad cable end before an install. The only drawback is this unit will not test all eight pins on a PCI-E Cable. It will only test six of the pins. What ever you do, do not put these six pins in the eight pin socket on the tester. It will short out the power supply.
