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 power consumption for the 870A is not bad at all. At stock speeds it pulled between 130 and 131 watts from the wall, while under load it topped out around 297.
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 was a little bit more of a concern as the heatsink for the Northbridge had to cover the Fuzion chip as well. This pushed the temps up quite a bit (about 4.5C hotter than the 890FX Northbridge on its own).
Although we have not covered the Fuzion aspect of the 870A Fuzion yet, we now have a very good idea of how this motherboard performs at a very basic level. The strengths and weaknesses are visible. We know that HDD performance is a little behind the current SB850 and that stock memory performance is right behind the current 890FX.
