Thermaltake Toughpower GF3 Snow 1200 Watt ATX 3.0 Power Supply Review

Efficiency

Straight away, the results are looking very good, with the 80 Plus Gold rating calling for 90/92/89% and this unit scoring around 92.5/93/90% putting it safely within the expected target.

PFC is great too, with it hitting a good 0.97 and above from 40% load and above, and only getting better as the overall load increases.

Voltage Regulation

This is some of the most consistent voltage regulation I’ve seen in recent years too, well within the 3% target we like to see, but keep in mind the 12V rail is so powerful (100A) that we have to split the load of three simulated 12v rails.
