Power Supply Tester Thermaltake Dr. Power III

The Thermaltake Dr. Power III is a compact universal ATX power supply tester engineered to support all modern ATX power supplies up to ATX12V v3.1. It includes the PCIe 12+4pin connector and detects SENSE0/SENSE1 sideband signals. An integrated LCD shows real-time voltages for +12V, +5V, +3.3V and +5Vsb and displays test results clearly. The tester is sized for convenient handling and is suitable for technicians and enthusiasts checking PSU health.

Advantages

The device provides real-time voltage readouts on an LCD, automatic and manual testing modes, and precise detection of PCIe 12+4pin SENSE0/SENSE1 signals to identify supported power levels (150W, 300W, 450W, 600W). A built-in diagnostic system alerts to low-voltage, high-voltage, no-voltage and PG faults; the LCD backlight remains white when no faults are detected and turns red with an audible beep when a fault is present. The tester is compatible with current ATX12V v3.1 power supplies and is backed by a 3-year warranty.

Suitable for (tasks / use cases)

• Checking and diagnosing desktop ATX power supplies
• Verifying PCIe 12+4pin connector power levels for modern graphics cards
• Routine maintenance and troubleshooting for PC builders and repair technicians
• Quick PSU checks during system upgrades or component swaps

How to use

Connect the Thermaltake Dr. Power III to the power supply using the appropriate ATX and PCIe connectors. Power on the PSU and select either automatic or manual testing mode. Read the live voltage values on the LCD for +12V, +5V, +3.3V and +5Vsb. Observe the diagnostic indicators: a white backlight indicates no detected faults, while a red backlight and beep indicate a detected issue. Use the displayed information to determine whether the PSU requires further testing or replacement.

Recommendations

For safe and accurate testing, ensure the power supply is disconnected from other system components before testing. Use the manual mode when you need to inspect specific rails or when testing non-standard configurations. Store the tester in a dry environment and follow the 3-year warranty terms for any service or replacement needs.
