ASUS AT3IONT-I Deluxe (NVIDIA ION) 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).

Interestingly the AT3IONT-I Deluxe does quite well on power consumption. At idle we see if draw only 23 Watts from the wall even when overclocked. Under load our power usage is still quite low with the max draw topping out at 39 Watts.

 

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 matter altogether. The large heatsink on the board still lets the MCP7A get quite hot. Our average temperatures were around 40c; this was on an open bench with no air flow. It is possible that inside a smaller case with good air flow that your temps here will drop significantly. If not, you may need to tack on a fan for more active cooling.
