Review: 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. Review: Product works as expected; the quality in the design and performance is great, and it works with current technology. ## Features - Universal ATX Power Supply Tester Supports Up To ATX12V v3.1. - Real-Time Voltage LCD Display - Precision in PCIe 12+4pin Connector Detection - Built-In Diagnostic System for Proactive Maintenance ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CZ2YF2FR | | ASIN | B0CZ2YF2FR | | Best Sellers Rank | #53,234 in Computers ( See Top 100 in Computers ) #372 in Computer Power Supplies | | Brand Name | Thermaltake | | Color | Black | | Customer Reviews | 4.7 4.7 out of 5 stars (143) | | Customer reviews | 4.7 4.7 out of 5 stars (143) | | Date First Available | 12 July 2024 | | Item Dimensions | 13.5 x 7.4 x 2.4 centimeters | | Item Weight | 0.33 Pounds | | Item model number | AC-069-OO1NAN-A1 | | Manufacturer | Thermaltake | | Manufacturer | Thermaltake | | Maximum Operating Voltage | 12 Volts | | Measurement Type | Voltmeter | | Minimum Operating Voltage | 12 Volts | | Model | AC-069-OO1NAN-A1 | | Power Source | Corded Electric | | Product Dimensions | 13.46 x 7.42 x 2.41 cm; 149.69 g | | Specification Met | CE, FCC, RoHS, UL | | Style Name | Modern | | UPC | 841163093788 | | Upper Temperature Rating | 50 Degrees Celsius | ## Product Details - **Brand:** Thermaltake - **Colour:** Black - **Item weight:** 150 g - **Power source:** Corded Electric - **Style:** Modern ## Images ![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 - Image 1](https://m.media-amazon.com/images/I/71X83t8+xiL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by W***G on 31 July 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.
