Thermaltake Toughpower PF1 650W Power Supply Review

Fan Speed
The Thermaltake Toughpower PF1 fan can operate under two different configurations. You firstly have the ‘standard’ mode which, as you can see in our results below, appears to operate on a three-tier speed system. The hybrid functionality effectively introduces a 4th-tier that doesn’t require the fan to operate until the PSU is at, roughly speaking, around 40% load. – The truth is, however, that while the Smart Zero Fan (hybrid) function is undoubtedly useful for those who value an ultra-quiet system, the fan is barely audible even in its standard mode. – It’s dealer’s choice, but with the hybrid mode on or off, the Thermaltake Toughpower PF1 is a quiet power supply!
It is, in fact, so quiet in its standard-setting that having the ‘hybrid’ mode on seems a little borderline pointless to me.
