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 US stores.
