ATX 3.1 power-supply tester

The Thermaltake Dr. Power III Pro checks ATX power supplies up to the ATX12V v3.1 specification. It reads voltage on the +12V, +5V, +3.3V and +5Vsb rails and measures the PG signal in milliseconds. A colour LCD shows real-time data and turns red with an audible beep when a fault is detected. The unit fits technicians, builders and repair professionals who need quick diagnostics.

Connector coverage for modern builds

The tester includes a 24-pin main-board socket, a 12V-2X6 connector, 4+4-pin EPS, 6+2-pin PCIe, SATA and Molex headers. It detects SENSE0 and SENSE1 sideband signals on the 12+4-pin connector and identifies GPU power levels of 150W, 300W, 450W and 600W. This lets a builder verify a PSU before installing it in a case without needing a full system.

Hand-held thermals and power draw

The compact black enclosure measures 74.8 x 135.8 x 24.4 mm and draws power directly from the supply under test. No battery or external adapter is required so the tool adds no heat or noise of its own. The colour display remains readable during extended test sessions while the audible alert sounds only when a rail falls out of specification.
