ASRock P55 Deluxe Lynnfield Motherboard - Power Usage and Heat Tests

With Lynnfield out, the question of which motherboard you should use for your new 1156 CPU comes to mind. The ASRock P55 Deluxe could be the answer.

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 new 2-chip solution offered by the Lynnfield and P55 show off their energy savings here. Even overclocked we see a more power efficient platform than the X58 which typically pulls about 174 Watts from the wall with a Core i7 975 onboard.

 

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.

Again we see the smaller size of the P55 chipset coming into play. The heat here was very low compared to other chipsets/motherboards. Considering the stock heat of the X58 Northbridge at 44c, the P55 does a very impressive job here.
