Thermaltake Toughpower 1350W Power Supply Review

Testing:

Efficiency and Power Factor:

The Thermaltake Toughpower 1350W is certified 80 Plus Silver which requires 85%, 88% and 85% efficiency at 20%, 50% and 100% DC loading with a power factor of 0.9 or greater at 50% DC loading. Power factor levels are rarely a problem, as is the case here, and the Thermaltake Toughpower 1350W gets closer than most to the efficiency requirements, 88%, 87% and 84%, following the OCC power supply testing methodology.

Lower power factor levels and better efficiency from a 230VAC supply but still very good.

Once again an excellent set of results from the Thermaltake Toughpower 1350W but what about electrical noise on the rails? Let's move on and take a look.

AC Ripple On DC Outputs:

I have consistently found the AC ripple levels on the DC rails to be more or less equal with an 110VAC or 230VAC mains supply. The results given below are for 230VAC only but I will continue to check the levels at 110VAC during testing and publish them below if there are any significant differences.

AC ripple/noise on the +3V3 rail at 230VAC

Oscilloscope settings: Amplitude = 5mv/div, Timebase = 5mS/div

AC ripple/noise on the +5V0 rail at 230VAC

Oscilloscope settings: Amplitude = 5mv/div, Timebase = 5mS/div

AC ripple/noise on the +12V rail at 230VAC

Oscilloscope settings: Amplitude = 5mv/div, Timebase = 5mS/div

AC ripple/noise on the -12V rail at 230VAC

Oscilloscope settings: Amplitude = 5mv/div, Timebase = 5mS/div

AC ripple/noise on the +5VSB rail at 230VAC

Oscilloscope settings: Amplitude = 5mv/div, Timebase = 5mS/div

The Thermaltake Toughpower 1350W produced a satisfactory set of results in this section with the noise levels on all the DC rails well inside the limits set down by the ATX12V specification.
