Thermaltake Dr. Power III, Power Supply Tester, Black

The Thermaltake Dr. Power III (AC-069-OO1NAN-A1) is a diagnostic tool for checking the voltage output and stability of ATX power supplies. It supports units compliant with standards up to ATX12V v3.1. The tester supports modern hardware via a PCIe 12+4 pin input, which detects SENSE0 and SENSE1 sideband signals for PCIe Gen 5.1 connections. It monitors four primary voltage rails—+12V, +5V, +3.3V, and +5Vsb—simultaneously. Real-time data appears on a built-in LCD, providing immediate feedback on PSU status. The device acts as a standalone tool for troubleshooting power-related boot failures or system instability.

The unit measures 74.8 mm in width, 135.8 mm in depth, and 24.4 mm in height. Its compact size makes it suitable for bench testing or field service. Users can choose between manual and automatic testing modes. An integrated alarm sounds if the power supply output falls outside specified tolerances; this helps identify faulty units before they are connected to other components. The device includes a 3-year warranty.
