The Thermaltake unit achieves top performance, taking the lead from the corresponding Seasonic and Corsair offerings. It only loses to the much more expensive FSP HPT850M unit.
The graph below depicts the cooling fan's average noise over the PSU's operating range, with an ambient temperature between 30 to 32 degrees Celsius (86 to 89.6 degrees Fahrenheit).
The fan profile could be much more relaxed, given the unit's high efficiency levels.
The following graph shows the PSU's average efficiency throughout its operating range with an ambient temperature close to 30 degrees Celsius.
The overall efficiency is pretty high.
