Thermaltake Toughpower GF1 1000W TT Premium Edition PSU Review 1

A common question in the PC world is, what is the most important component in a computer? Gamers tend to say GPU, and workstation users might throw down on CPU or maybe even memory or storage. While those are all certainly important to user experience, nothing ruins it quite like a failed power supply. It’s even worse if it takes some or all of your components down the hole with it. Thermaltake won’t let that happen with its Toughpower GF1 series power supplies. We’ll be taking a look at the massive 1000W Toughpower GF1 but it also comes in 1200W and smaller 650W, 750W, and 850W flavors to cover about any build. Thermaltake forgoes RGB bling and focuses on performance on longevity with ultra-low ripple and 100% Japanese capacitors, and build quality worthy of a 10-year warranty.


PC Test Bench would like to thank Thermaltake for sending over the Toughpower GF1 1000W TT Premium Edition for us to check out!
