Power consumption was measured after 5 minutes of load under three scenario: Furmark, Unigine Heaven and desktop idle in sequential order with 2 minutes of downtime in between each test. The measurement was taking using an Energenie ENER007 power meter and measured for the whole system at the power supply, excluding the monitor.
While Furmark and desktop idle provide stable and consistent power read-outs, Unigine Heaven does not so the power reading is taken as the peak value that occurs in Scene 2 of 26.
Power consumption was a little lower than anticipated. Perhaps MSI has implemented more efficient VRMs than on its Gaming X or the lower VRM operating temperatures allow things to run more efficiently. Either way power consumption is absolutely fine for the performance on offer.
