Since power consumption is a big deal these days, we ran some simple power consumption tests on our test beds. The systems ran with identical power supplies, Solid-Sate Drives, Memory kits and motherboards from the same company. To measure idle usage, we ran the system at idle for one hour on the desktop with no screen saver and took the measurement. For load measurements, we fired up the AIDA64 system stability test.
The overclocked performance of the Intel Core i7 3770k has clearly been better than at default speeds. Though when overclocked the Intel Core i7 3770k power consumption increases substantially. At idle the default settings draw only 81 Watts at idle, overclocked to 4.7GHz the idle power consumption increases to 118 Watts which is a 45.7% jump. Once we loaded up the Intel Core i7 3770k with the AIDA64 System Stability test the system power consumption jumped from 142 Watts up to 221 Watts! That’s an increase of 55.6%. If you’re overclocking you will lose efficiency, but gain overall system performance.
