The Thermaltake Toughpower GF A3 1050W is an ATX v3.0 and PCIe 5.o compatible unit, thanks to its 12VHPWR connector that can deliver up to 600W to the GPU. With only 140mm depth, it has a minimal footprint, which along with the fully modular cable design, will be an asset during installation.
The Thermaltake Toughpower GF A3 1050W will be included in my best ATX v3.0 & PCIe 5.0 PSU picks article.
After the flagship GF A3 unit, with its 1200W max power, I thought I’d look at the 1050W model. The entire GF A3 line is made by HKC, an OEM that Thermaltake has mainly used so far. I am not sure if TT will continue the GF3 models, which are made by CWT and High Power or will replace them with the GF3 A3 ones, but for the moment, both are available, with the latter having slightly lower prices.
The Toughpower GF A3 1050W is Platinum certified by Cybenetics in efficiency, while in noise, it has a Cybenetics A- badge (25-30 dB[A]). It uses a 120mm sleeve bearing fan, while the 1200W model uses a fluid dynamic bearing fan. I am not sure why TT used different fans in these two models, but I don’t approve of the drop in the fan’s quality. There is a semi-passive operation available, which can be switched off if you want the fan to be in operation constantly, and the provided warranty is ten years long, so TT is confident of the PSU’s reliability through time.
