Thermaltake Toughpower GF1 850W Power Supply

In a category where the Corsair RM850x and the similar capacity Seasonic Focus Plus Gold dominate, Thermaltake offers an alternative option featuring RGB lighting, excellent performance, and quiet operation, which might not be as quiet as the RM850x, but it takes the lead from Seasonic's offering. In terms of performance, the Toughpower GF1 850W is close to the Corsair and Seasonic models mentioned above. Its primary disadvantage is the restricted availability, for the moment at least, since due to the recent tariffs, Thermaltake pulled it out from all major US online stores. Currently, you will only find it in the premium store at an eye-watering price.

Thermaltake's Toughpower GF1 ARGB line consists of three members with capacities ranging from 650W to 850W. They are based on a platform that is provided by Channel Well Technology. The fully modular cable design along with the 16.8 million-color RGB fan with the 18 LEDs are two features that most gamers will appreciate. The PSU's RGB lighting can also be synchronized with compatible mainboards from Asus, Gigabyte, MSI, and ASRock.

When it comes to performance, Thermaltake claims that it is high enough to meet the demands of enthusiast users and overclockers, and the same goes for reliability. A ten-year warranty supports all GF1 models, providing an extended peace of mind to their future owners. Finally, the RGB fan comes with a Hydraulic bearing, which, along with the appropriate fan speed profile, can easily lower the overall noise output to below 30 dB(A) levels.

We will take a look at the strongest member of the line, featuring 850W of power. The GF1 850W is strong enough to support a potent gaming system. It also sports a quiet operation since it scores a LAMBDA-A- rating in Cybernetics' scale, which translates to a lower than 30 dB(A) overall noise output.

There are plenty of connectors to deliver the unit's full power with ease. Besides a pair of EPS connectors, you also get six PCIe ones along with twelve SATA and four 4-pin Molex. The distance between the peripheral connectors is ideal at 150mm, and all cables are long enough to allow the installation in large, full-tower chassis. Finally, there are no in-line caps, which will make the cable management and routing processes much more straightforward.
