Thermaltake today introduced the Dr. Power III Pro (model: AC-083-OO1NAN-A1), a handy tool to test modern ATX 3.1 power supplies. This was first showcased by Thermaltake at the 2026 CES. The tester lets you check voltages and stability of the various connectors of an ATX 3.1 PSU, including a 600 W-capable 12V-2x6 connector, a 24-pin ATX, a 6+2 pin PCIe power, a 4+4 pin EPS, SATA power, and 4-pin Molex. The tester lets you check if the various voltage domains are within safe ranges, so you know if your PSU is broken. An LED segment display puts out measurements for the various domains, while a buzzer sounds alarm if something is off-range. Available from July 9th, the Thermaltake Dr. Power III Pro tester is priced at $49.99.
