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 P7P55 WS SuperComputer is very power efficient at stock speeds. This is thanks to the EPU-6 software and the ASUS EPU hardware. Of course, once we overclock the CPU all bets are off and the power usage picks up quickly.
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.
Heat generation was another matter. The P7P55 WS SuperComputer can put off a good deal of heat. This means that to keep this cool inside a case you had better make sure you have good ventilation and air flow (we told you all the fan headers would come in handy).
