We were very impressed by the new Thermaltake TR2 700 W, as in the past the TR2 series used to be a very entry-level power supply series, with low-efficiency units. The TR2 700 W proved to be a flawless unit, with high efficiency between 82.6% and 87.4%, voltages closer to their nominal values all the time (3% regulation), and very low noise and ripple levels.
The only negative aspect of the TR2 700 W is the relatively reduced number of SATA power connectors (seven), but since it is targeted to the mainstream market, this should not be a problem.
What we can’t understand is why Thermaltake decided to use the name “TR2” for this new power supply series. As mentioned, several of the old TR2 models presented lousy performance, and many people may think that the new models have the same problem.
We believe that the price of this power supply is right. At USD 100, it faces the direct competition of the new OCZ ZT Series 650 W, which has a full modular cabling system and is also a “flawless” product. This model from Thermaltake, however, presents higher efficiency.
