ASUS Maximus III Extreme (P55 Express) Motherboard - Power Usage and Heat Tests

P55 might be old news, but ASUS has put their engineers to the task of squeezing every ounce of performance out of it with the Maximus III Extreme.

Power Consumption


We are now able to find out what kind of power is being used by our test system and the associated graphics cards installed. Keep in mind; it tests the complete system (minus LCD monitor, which is plugged directly into an AC wall socket).

The Maximus III Extreme does not come with the EPU/EPU-6 software. It is an overclocking motherboard after all and is meant to have large amounts of power pushed through it. Still, I was pleasantly surprised by the power usage even at the higher clock speeds.


Heat Generation


As a new measure, we are now monitoring the heat generation from the key components on the motherboard; this being the Northbridge, Southbridge (if it contains one) as well as the Mosfets around the CPU. The results are recorded at idle and load during the power consumption tests.

The heat generated by the components on the board was not too terribly bad. The NF200 did get a little hot, but it was nothing that a well-placed fan would not take care of. The P55 and other SB components did quite well at keeping cool even when pushed to high clock speeds and with a few extra mV.
