Review: Great tool - I build PCs and help family members troubleshoot their PCs. I saw this in a video from youtube and wanted to try it out since I've experienced with a few bad PSU. Once it arrived, I used it and it actually works. The only thing I haven't experienced is using this tool on a bad PSU. This tool works, very easy to use, I'm sure it's time saving and very accurate. Small and light. The display is very easy to read. To whoever troubleshoot and build PCs for fun or a living, this is a must.
Review: Excellent power supply tester with latest compatability - 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.

### ⭐⭐⭐⭐⭐ Great PSU Tester! GreatValue for Peace of Mind!
*by J***T on June 7, 2026*

The Dr. Power III is a great tool for verifing the condition of Power Supplies. The name says ATX, but the Dr. Power III ATX Power Supply Tester can test SFX PSU's as well. It has connections for the following: 12+4 pin, 24 pin, PCI-e 6 or 8 pin, Sata, CPU 4 or 8 pin, and Peripheral (molex) connections! It is very simple to use, just plug in the connections available on the PSU, turn it on, and cycle through the readings by pushing the button. It uses the power from the PSU, so no batteries necessary! Be aware, when you turn off the PSU the tester will turn red and beep, letting you know that the power is no longer correct, and that is what it should do. Just unplug the cables and its ready for the next Test!
