Thermaltake Dr. Power III ATX Power Supply Tester/Support up to ATX12V v3.1 with PCIe 12+4pin Connector/Voltage Output for +12V, +5V, +3.3V, and +5Vsb, AC-069-OO1NAN-A1

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.

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.

The best PX power supply tester that I have ever seen or used. It’s easy to use and has been a great help to verify that a power supply is in perfect condition and to identify a problem with a defective power supply. This is great for using to build a new PC to make sure I’m starting with a good PSU.

Works like a dream. Easy to use.

One of the best power testers I’ve ever used if you want a repair shop this is a great item to have in your shop the day I bought it I needed to use it to test the power supply

Tester is very good, but i wish they lable the plugs better. You habe to really look hard to read the black on black lettering Other then that, its a good psu tester

Seemed to work fine

I had a cheaper tester that looked like something out of the 60s. It would tell you about your power rails, but it required a book to understand. This thing is clear as a bell. As you can see in the pictures, you can clearly make out power levels for the 5V, 12V, 3.3V, 5VSB, and PG. The book for the tester also lists the appropriate ranges for a PSU, so you can quickly tell if your power supply is good or not. Worth every penny.
