The Dr. Power III power supply tester from Thermaltake has been completely redesigned and supports all ATX power supplies available today, up to ATX12V v3.1. The device reliably detects the SENSE0/SENSE1 sideband signals of the latest PCIe 12+4 pin connector and distinguishes power levels of 150W, 300W, 450W, and 600W, ensuring compatibility with a range of PCIe Gen 5.1 graphics cards and components. The LCD display allows the user to easily and clearly read and interpret the test results. The real-time LCD monitoring shows the output voltage for +12V, +5V, +3.3V, and +5Vsb. Instant feedback facilitates the immediate assessment of the power supply performance, enabling informed decisions regarding the system’s power supply. Manual and automatic test modes are available, allowing quick diagnostics of the power supply's output status. The Dr. Power III power supply tester features a robust integrated diagnostic system that identifies issues such as under-voltage, over-voltage, missing voltage, and PG alarm systems. If no error occurs during the test, the LCD backlight remains white. Once an error is detected, the LCD backlight turns red, and a beeping sound is triggered.
