Thermaltake announced the Dr. Power III Pro tester, a $49.99 device for diagnosing modern ATX 3.1 power supplies. First shown at 2026 CES, it checks voltages and stability across connectors like the 600W-capable 12V-2x6 and 24-pin ATX. The tester uses an LED display and buzzer to flag issues, helping users identify faulty PSUs.

ATX 3.1’s 16-pin PCIe connector poses challenges for testing, but the Dr. Power III Pro supports 6+2-pin configurations. It also checks 4+4-pin EPS, SATA, and 4-pin Molex connections. This ensures compatibility with high-end components like graphics cards and CPUs, critical as power demands rise.

The tester’s compact design makes it ideal for builders and technicians. With a July 9 release date, it arrives as PC hardware trends shift toward higher efficiency standards. For $49.99, it offers a cost-effective alternative to lab-grade equipment, democratizing diagnostics for hobbyists.

Dr. Power III Pro bridges a gap in consumer-grade tools, empowering users to maintain system reliability without specialized expertise. As ATX 3.1 adoption grows, such devices will become essential for troubleshooting modern setups.
