As the name would suggest this new design is 80 Plus Gold certified, fully modular and ships with Fractals new ‘UltraFlex' cable design.

For the purposes of this review, Fractal sent us their higher wattage 650W model. It incorporates a high grade 120mm Fluid Dynamic Bearing fan with a semi passive ZERO rpm mode in lower load situations. We know that Fractal have worked with Seasonic on the design of this product – its based on the Seasonic SGX.
