Value and Conclusion

  • The Thermaltake Toughpower GF1 ARGB 850 W retails for $179.99 in the US and €159.90 (incl. 20% VAT) in Europe.
  • Delivered full power at 47 °C
  • High overall performance
  • Satisfactory transient response at +12V
  • Good ripple suppression (without using in-cable caps)
  • Good build quality
  • Full protection features set
  • Lots of connectors (including 2x EPS & 6x PCIe)
  • Adequate distance between peripheral connectors
  • RGB lighting (controllable manually and through software)
  • 10-year warranty
  • High price (because of the tariffs) and limited availability in the US
  • Not all that quiet (LAMBDA-S++, 34.63 dB[A] overall noise output)
The Thermaltake Toughpower GF1 ARGB 850 W is an interesting product, not so much because of its plethora of RGB lighting modes, but mostly because of its good performance that is on par with other popular choices in this wattage category, including the Corsair RM850 and RM850x models and the Seasonic Focus Plus Gold unit of similar capacity. The main disadvantage of Thermaltake's offering seems to be its limited availability and increased price in the US because of Trump's tariffs, which affect all products manufactured in China. Large manufacturers are already searching for alternative options, and according to my sources, CWT, the OEM of this Thermaltake product, already has a factory in Vietnam which it will apparantly fully utilize in the near future.

The area where the Toughpower GF1 could be improved is noise output, which is high despite the semi-passive operation. Apparently, the fan profile is more aggressive than necessary, especially with loads above 575 W. Since this is an efficient power supply, CWT could make the fan profile looser without compromising the unit's reliability over the long term. I know that most brands try to stay on the safe side. However, while a warranty of seven or ten years is very long, such long warranty periods are unrealistic for products like power supplies where power input quality plays a crucial role. Don't expect your PSU to live that long if you are in an area with an unstable mains grid and don't protect it with a decent UPS, or at the very least a good power conditioner. Every PC in my lab (and not only) is connected to a branded UPS, and I have not had a PSU failure for many years even though the power quality in my area is mediocre.

Hopefully, Thermaltake will find a way to bring this model to the US market at a competitive price. As I was informed, it won't be available through normal retail channels, at least at first, so the only way to get one is through Thermaltake's eshop, where it was out of stock when this review was being put together.
