Stress Testing and Power Consumption
Stress Test — Putting It All Together

Another test we added to the motherboard suite this time around was the stress test.  In this we take all the on-board components and make them all work together just to see if they play nicely. 

In our case here this meant running WMP10 on an HD video, having PCMark05 run some hard drive tests, running HDTach on the external USB hard drive, playing a large WAV file and running the network bandwidth test, all at the same time.  The tests were looped for an hour and we listened for sound ‘jumps’ or video stutters or anything similar.

There were absolutely zero hiccups on the Alienware Aurora 7500 system; and we expected this from a professionally build and designed PC that comes with a warranty. 

Power Consumption

In many cases, looking at the power consumption of motherboards and chipsets can seem a little over dramatic.  After all, when your GPU eats up a couple hundred watts on its own, whats a few more for a chipset?  Regardless, we felt the need to use our power meter to test for power consumption at the wall. 

Idle power was taken at the Windows desktop while load results were taken from a dual-threaded CineBench run.

Because the DIY system didn’t include two hard drives, fans, LEDs and used a different graphics card, its power usage was going to obviously be lower.  That being said, the Aurora 7500 actually used suprisingly little power under idle and load with all the features and extras included with the unit.
