ASUS P7F7-E WS SuperComputer (3450 Express) Motherboard - Power Usage and Heat Tests

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 draw from the P7F7-E WS is good considering we tested it with a SATA 3.0 and USB 3.0 drive attached. The idle draw here is quite good, although this could change quickly with one or two Firewire 800 drives attached.

Under load the P7F7-E starts firing on all cylinders. We still see it show good power draw as the two boards that are in the lead here do not have SATA 3.0 or USB 3.0.

 

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.

Heat is another story. It looks like the small heatsink at the end of the chain (there is an NF200 in the middle) is just not as efficient as some of the cooling on the enthusiast based products. It can keep the temps in the right envelope, but we would like to see a little better cooling.
