GIGABYTE P55A-UD7 (P55 Express) Motherboard - Power Usage and Heat Tests

We take a close look at the UD7 flavour of GIGABYTE's P55 motherboard to see if the 24 phase power really makes a difference.

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 GIGABYTE P55A-UD7 is a power thirsty board. We found that even at stock speeds it pulls a (comparatively) large amount of power from the wall. At load things were not any better.

 

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.

On the heat side of things the P55A-UD7 again was hotter than the rest at idle. However, when we pushed the board the temperatures certainly did not go up as much as on other boards we have tested. This is a good indication that the cooling on the P55A-UD7 can handle the extra heat generated when made to work hard.
