To test the stability I stressed all components of my system at the same time, and monitored the fluctuations of the different voltage rails.
To stress all components I used following tools:3DMark 2001 SE
Windows defragmentation tool
Now my CPU, VGA card and hard disk were under load.
In the shop, they said the PSU could be compared with a Chieftec PSU. Well, lucky me, I've got a 360Watt Chieftec PSU, lets check it out!
Check the MBM high/low file for the results:
AOpen 300 watt
What does this mean? If we look at the averages we see that the 5 V line is stable, with an average of 4.98 V. And it stays stable during the stress tests. The difference between the highest and lowest peak is only 0.03V. Negligible!
The 12 V line on the other not really bad, average of 1.82, but while stressing all components and consuming more power, the line drops to 11.73. Here the difference between highest and lowest peak is 0.2 V already. No disaster, but not perfect. :)
Chieftec 360 watt
I've thrown in this Chieftec PSU for comparison. What can we see here? While the AOpen never topped over + 5 V, the Chieftec never drops below 5 V. The 12 V line is almost the same, only the difference between lowest and highest value is bigger. But still no disaster...
So, I could say that both PSU's are an equal performer on my system. Too bad I don't have a very heavy VGA card, so that I could stress the PSU's better...
