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).




The P55A and P55 boards from GIGABYTE use the same amount of power. There is no real increase in power between the two boards, or any reduction in the newer board.


Heat Generation


As a new measure, we are now monitoring the heat generation from the key components on the motherboards, 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 is almost identical between the two GIGABYTE boards also, since they use the same Mosfets and heatsink design to cool the board and components.

    Thanks for letting us comment. We would just like to clarify that it is possible to run SATA 3 and USB 3.0 while running CrossFireX and SLI on the GIGABYTE GA-P55A-UD6. If two graphics cards are plugged in, the BIOS will automatically default to runnin
