Review: Surprising and helpful - This actually surprised me. Had a PSU I needed to test and couldn't believe this was on offer from Thermaltake no less. And at a very reasonable price. The readouts have been accurate and the fact that it includes full ATX 3.0 functionality with a 12VHPWR port is big win for this. Overall exceeding all expectations and well worth the price.

### ⭐⭐⭐⭐⭐ A top tier PSU tester!
*by G***G on December 13, 2025*

The best PX power supply tester that I have ever seen or used.

This is great for using to build a new PC to make sure I’m starting with a good PSU.

### ⭐⭐⭐⭐⭐ Excellent power supply tester with latest compatability
*by W***G on July 31, 2024*

Instead of risking my computer with an old Corsair AX750 that had been collecting dust and spider webs for five years, I decided to invest in a Thermaltake Dr. Power III. And boy, am I glad I did! It failed the PG test spectacularly - displaying an “F,” the backlight turned red, PG kept flashing, and beeping loudly. Next, I used the Dr. Power III to test a brand new FSP Hydro PTM X Pro 1200W ATX 3.0 PSU. I plugged in everything: CPU, PCI-E, SATA, Molex, and even the 12VHPWR. They all tested good! The Dr. Power III uses the ATX 24-pin as its power source and displays all connections and their respective voltages on the screen. Testing is a breeze - just press the button to cycle through the tests or hold it for five seconds for auto-testing. During the tests do not disconnect or turn off the PSU as it can cause damage. The build quality of the Thermaltake Dr. Power III is superior to those cheap PSU testers. It’s lightweight and capable of testing the latest ATX 3.1 PSUs. However, it does feel a bit cheap due to its plastic construction and is more expensive. Despite that, I highly recommend the Thermaltake Dr. Power III if you have an ATX 3.0 or higher PSU and/or have multiple PSUs to test. It’s a reliable and efficient tool that makes PSU testing straightforward and hassle-free.
