ASUS P7P55D-E Pro (P55 Express) Motherboard - Power Usage and Heat Tests

We take a look at the USB 3.0/SATA 3.0 enabled P7P55D-E Pro; the baby-bother to the P7P55D-E Deluxe and Premium. Talk about sibling rivalry.

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).

Power consumption between the P55s is about equal. The ASUS P7P55 does do much better while idling at stock speeds due to the EPU-6 software and the EPU engine. However, once you start pushing it or overclock it all of that is out the window.

 

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.

As with power consumption, the ASUS P7P55D-E Pro generates a lot more heat than the ASRock. Then again, the ASUS has more under that heatsink than the ASRock does.
