ASUS Crosshair IV Formula (AMD 890FX) Motherboard - Power Usage and Heat Tests

AMD has dropped a 6 Core CPU on the consumer and ASUS has a board with performance and features to match.

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 from the AMD based Crosshair IV Formula was a bit more than we expected. We had thought that with AMD's claims of better power and money savings we would see this setup trounce the Intel boards/CPUs. However, this is not always the case.

 

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 same story was repeated with heat generation. The AMD based Crosshair was a little hotter than the competition in many cases.
