We test power consumption at the socket with a calibrated meter under the following conditions.
1: when idle
2: running Tomb Raider at Ultra HD 4K with ‘ultimate' image quality settings.
The monitor is not factored into the power draw, just the demand via the system power supply.
Power consumption falls in line with what we would expect from a system featuring an overclocked 4790k and Fury graphics card – it demands around 350 watts under full load.
