Thermaltake Toughpower SFX 1000 Watt Fully Modular 80+ Platinum Power Supply Review

Efficiency

This PSU is rated for 80 Plus Platinum, and of course, it held up great throughout the testing, scoring well above 90% at all loads.

PFC (Power Factor Correction)

The PFC is excellent, and the closer to 1.0 the better, as this means less conversion and less heat generation, and as you can see, it starts of strong, but gets even better at higher loads.

Voltage Regulation

Ideally we can’t to see voltages within 3% of their targets, and this is especially true of the 12v, which actually has some of the most accurate results I’ve ever seen, hitting an average deviation of… zero!
