Does anyone know how much W the I7-7700k uses?

Solution
"Intel Core i7-7700K vs. Core i7-6700K @ 4.5 GHz
For our performance benchmarks, we had the Core i7-7700K compete against a Core i7-6700K at the same frequency. The latter fared pretty well, but was also close to its maximum overclocking potential. We have an above-average chip, but it's far from a golden sample.
Consequently, we end up comparing a solid Skylake CPU to a bad Kaby Lake sample at the same clock rate. The result’s somewhat of a shocker: our Skylake CPU comes in just below Kaby Lake in our power consumption test, in spite of its manual overclock and a slightly higher voltage set in the BIOS.
This means that a decent retail Core i7-6700K beats a below-average retail Core i7-7700K. We already feel sorry for the online...
