Thermaltake Toughpower GF1 1000W TT Premium Edition PSU Review


System Config:

  • Intel Core i9-10900K
  • Asus ROG Strix Z490-I Gaming
  • Nvidia RTX 2080Ti Founders Edition
  • 64GB (2x32GB) Viper Steel 3600Mhz
  • Samsung 960 Pro 2TB


We’ll start out saying we aren’t equipped to do extremely detailed electrical analysis required to pick apart a modern power supply. It takes laboratory-grade dedicated equipment so we’ll have to make do with some less precise testing.


While we normally use a good Fluke Digital Multi-meter, we’ve found the onboard monitoring solutions in modern motherboards to be quite accurate and able to be easily logged with utilities like HWiNFO. This is especially true of higher-end enthusiast-class boards that are oriented towards overclocking. We start monitoring and run a series of benchmarks and stress tests to ramp the system up and down from idle to full load of every component.
