Intel Core i7 4770K “Haswell” Processor Review

Power Consumption

To test power consumption, we monitor the overall power of the system through a plug-in electricity usage monitor at an idle and load state. This allows us to show the fluctuation between how much power draw the system takes at idle and at load. By monitoring the overall usage of the whole system, it gives an easy comparison if you wish to do the same yourself as opposed to buying very expensive individual testing equipment.

Our power consumption results showed something very strange – that the i7 4770K actually uses more power than the i7 3770K. We can only really put this down to the motherboard we are using which must consume a lot more power than previous motherboards we have tested with on different platforms. Either way we should of seen CPU power consumption drop by around 5-20%.
