Skylake-X and Threadripper CPUs, and GTX 1080 Ti and Vega GPUs have one thing in common: they consume a lot of power. If you want to build a high-end system, you have to choose a fitting power supply. We tested 39 models that can supply 700 or up to and including 850 watts.

During the last couple of years we have gotten used to processors offering improved performance as well as lower power consumption with every new generation. However, this trend seems to have come to and end for now. The brand new Intel Skylake-X processors consume (in part due to the increase in core count) a lot of energy, which can also be said about AMD's Ryzen Threadripper. While the Nvidia 10-series GPUs consume less energy than the models in the 9-series, the 1080 Ti (thanks to its enormous amount of transistors) still consumes more power than every other common Nvidia GPU of the last couple of years.
