Thermaltake Toughpower iRGB PLUS 850W Gold Performance

The basic goal of any power supply is to provide clean and consistent power to your components, which the Thermaltake Toughpower iRGB PLUS 850W Gold excels at. Its single +12V rail architecture guarantees that power-hungry components like GPUs and CPUs receive stable voltage. The PSU consistently produced steady voltages during testing, even under severe loads, which is critical for system stability and durability.

The Gold accreditation indicates that this power supply is very efficient. In practice, this leads to cheaper power expenditures and decreased heat output. Under ordinary loads, the 90% efficiency is outstanding, implying that less energy is lost as heat. Because of the reduced heat generation, the fan will be quieter during regular operation.

During low to moderate loads, the Smart Zero Fan function performs an outstanding job of keeping the PSU quiet. The fan only activates when necessary, and even then, owing to the 140mm fan design, it is relatively quiet. Even under stress, we found that noise levels were considerably below acceptable standards throughout our tests.
