@nemobis I haven't measured it myself, but for example the CPUs range from 50-100W TDP or so, depending on CPU model. By the way I always ship with four sticks of RAM (4x4GB or 4x8GB) on these machines.
With that, and an SSD, plus intergrated graphics, I'd say it probably consumes no more than about 100-150W on the highest of workloads, probably much lower on idle. Add 50W, if you have a graphics card.
The PSU is rated 80PLUS and nominally 250W or so; therefore, I would expect lower than 200W.
