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 RIIIG does well on power consumption. At least it does at idle and at stock speeds. When you ask it to perform and push the CPU then, it demands quite a bit more power from the wall.
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.
Here we see the consequences of not having more room to play with. The NB on the RIIIG gets hot, very hot, and it takes a while to cool down after it gets up there. Perhaps getting a hold of one of the old ASUS add-on fans from the socket 775 days would help here.
