GIGABYTE EP43-DS3R Motherboard - Power Usage and Heat Tests

Today GIGABYTE has its EP43 board on the chopping block, based on Intel's new mid-range chipset.

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.

Power wise the EP45 and EP43 boards are pretty well close spec'ed; the extra power rails on the P45 board help it to get a bit better efficiency under load conditions when compared to the EP43.

 

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.

Due to a lack of heatpipe cooling on the EP43 board, it heats the components up a bit more. And with no cooling at all on the Mosfets we see that they heat up even more. Clearly the heatpipes on GIGABYTEs other boards do a good job.
