MSI Z77A-G45 GAMING Motherboard Power Consumption
Most OEM built PC’s ship with standard or proprietary power supply and they tend not to exceed 450 watts top end. While that might be enough power for a standard PC, overclocked multi-GPU enthusiast systems can easily exceed 700 or 800 watts under load, and can go even higher with extreme cooling and high voltages.
Perhaps this is why all CPU and GPU vendors are embedding their products with power-saving features, and why motherboard vendors try to add even more. And the use of these features can make a significant difference in the power use of your system.
To test the power-saving features of the MSI Z77A-G45 GAMING motherboard, I measured the power draw of the system (with no video card, and the monitor connected to the iGPU) with all the power-saving features in the “ECO” section of ClickBIOS II enabled, and with all the power-saving features disabled.
|Windows Login||Idle at Desktop||AIDA64 Stability Test||Sleep|
|ECO enabled||32 watts||34 watts||108 watts||1 watt|
|ECO disabled||57 watts||62 watts||109 watts||1 watt|
|ECO disabled, manual OC||69 watts||71 watts||136 watts||1 watt|
Take from this what you will, but the results are clear cut enough to convince me that that it is worthwhile enabling the power saving settings available on the MSI Z77A-G45 GAMING motherboard. In the 60’s and 70’s there was a big ecology movement after oil prices had risen sharply and we collectively realised that we could not sustain our then current level of consumer lifestyles. In the ensuing years the economy changed for the better and consumption ramped up sharply. We now find ourselves consuming more than ever and we once again need to realise that natural resources can’t possibly sustain us forever. We need to demand more energy efficient products. We need to demand better built and longer lasting hardware. But most of all, we need self control and a more conscious approach towards our consumer habits.
