Whether you’re conducting pre-build checks or troubleshooting existing setups, the Dr. Power III offers straightforward voltage and PG value detection. To initiate testing, simply connect the power supply and the Dr. Power III using cables, press the check button, and the test will commence. The Dr. Power III supports various connectors, including the latest 12+4pin, 24pin, PCIe 6/8pin, SATA, CPU 4/8pin, and peripheral connectors. It is compatible with all contemporary ATX PSUs.

The Dr. Power III goes above and beyond by meticulously detecting the SENSE0/SENSE1 sideband signals of the latest PCIe 12+4pin connector, allowing it to distinguish power levels of 150 W, 300 W, 450 W, and 600 W. The output voltages are displayed in real-time on an LCD screen, ensuring that users can easily read and interpret the information.

This versatile device also incorporates a built-in diagnostic system that detects issues such as low-voltage, high-voltage, no-voltage, and PG alarm systems. In case of any faults, users are immediately alerted through a red LCD backlight and a “beep” sound. On the other hand, if the test proceeds smoothly without any issues, the LCD backlight remains white, providing users with instant feedback.

The Dr. Power III offers both manual and automatic testing modes, allowing users to choose the approach that suits their needs best. Additionally, Thermaltake provides a 3-year warranty for the Dr. Power III, ensuring reliability and peace of mind for users over an extended period.

In summary, the Dr. Power III simplifies the process of diagnosing power supply issues with its support for the latest connectors, real-time LCD display for immediate feedback, and user-friendly design. It is the perfect tool for testing high-end power supplies.
