Thermaltake Toughpower PF1 650W Power Supply Review

Efficiency

Coming as an 80-Plus Platinum rated power supply, the Thermaltake Toughpower PF1 certainly sets the bar pretty high. This is, in fact, the 2nd highest efficiency rating possible and one significant step up from the far more generic ‘Gold’ standard. So, with this in mind, how well does it meet that remit?

Well, the short answer is fantastically! – Based on the results provided in our testing, the Thermaltake Toughpower PF1 doesn’t just easily attain its Platinum efficiency rating, but in many respects, it borders on the absolutely top-spec ‘Titanium’ level. The efficiency performance seen in this PSU is nothing short of remarkable!

PFC (Power Factor Correction)

Although starting fairly low, as is both perfectly common and normal for the vast majority of power supply models, once you ask the Thermaltake Toughpower PF1 to start working a little bit harder, the results very quickly ramp up to some highly impressive levels. Admittedly, the PFC results seen here are not quite as high as we’ve seen on other Thermaltake PSU products, achieving a maximum score of 0.97, however, this is more than respectable!

Voltage Regulation

Regardless of the load output, the Thermaltake Toughpower PF1 provided excellent voltage regulation testing results. A factor clearly demonstrated in the fact that the overall average deviancy across all the rails is amazingly low. These are, without a doubt, some of the tightest results we’ve seen for quite some time and clearly indicates that this is a quality PSU design.
