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).






Using only the IGP the 890GPA-UD3H is pretty good on power draw even with the Phenom II X6 1090T. This will be of interest to many business and mainstream users. For the gamer or enthusiast, well, things are a little different. Adding in a high-powered GPU is going to increase the power draw (especially under load).


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.






Heat generation was not bad at all. In fact, through all three of our test runs the Northbridge kept fairly cool. It would seem that the cooling that we had our doubts about does actually work well.
