Hello. I have been planning on "upgrading" my i3 6100 for an i7 4960X + 24GB of DDR3, however, i'm not sure if my 600W PSU would handle it all. I have used a couple of PSU calculators and the general result was 420W, but i saw some i7 benchmarks and i noticed that it consumes about 300w of power in maximum load, and considering all other components, i'm not completely trusting those calculators, and would like a better answer.
