NVIDIA nForce 730i / GeForce 9300 Chipset Review - Power Usage and Heat Tests

NVIDIA has some of the best IGP based chipsets out. Today the newest member of the family arrives on the 730i mGPU.

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).

 

There are a few important notes to remember though; while our maximum power is taken in 3DMark06 at the same exact point, we have seen in particular tests the power being drawn as much as 10% more. We test at the exact same stage every time; therefore tests should be very consistent and accurate.

 

The other thing to remember is that our test system is bare minimum - only a 7,200RPM SATA-II single hard drive is used without CD-ROM or many cooling fans.

 

So while the system might draw 400 watts in our test system, placing it into your own PC with a number of other items, the draw is going to be higher.

In our power usage tests we see that the 9300 GPU is able to keep the power down over the previous generation. With a die shrink we get more a power conscious setup. It even managed to keep up with the G45 based system. The 7150, despite being cut down, uses quite a bit of power.

 

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.

Here we see that all three setups are pretty identical in terms of heat generation.
