Conclusion
The Dr. Power II PSU tester is a pretty simple and easy to use device. The unit is well made and doesn’t feel cheap in any way. It’s certainly a huge improvement from the original Dr. Power PSU tester. The tester can be found online for around $40-$50, which is a pretty hefty price for a PSU tester, especially considering most others can be found under $30 without much effort.
If you’re looking for a PSU tester and like Thermaltake products, then this would be a great purchase for you. It has a 3 year warranty, but I would think it should last you longer than that, which may make it a worthy investment. ThinkComputers would like to award the Thermaltake Dr. Power II Power Supply Tester a 9 out of 10 score.

Pros:
- Well built
- Easy to use
- Large LCD screen
- Built-in alarm system
Cons:
- Expensive
