The test system:
|CPU||Athlon XP 1900@2000+ (12*139MHz)|
|Memory||512MB DDR 166@172MHz (344MHz)|
|Video Card||Radeon 9000Pro|
|Harddisk||Seagate Barracuda V 60GB|
The benchmarks were made by using the system above. Voltage measurements were made by motherboard sensors and a multimeter for more accurate test results. The load tests were made by running 3dmark 2003 several times one after another.
The idle voltages are very stable. The +12V rail waves a bit, but clearly inside the parameters. The +3,3V and +5V rails are exemplary. Only a slight irregularity on those too.
The load measurements have nothing different to offer. The lines are waving a little, but moreover inside the parameters.
|5 V Idle||5.03 - 5.04 V|
|5 V Load||5.03 - 5.04 V|
|12 V Idle||12.35 - 12.36 V|
|12 V Load||12.36 - 12.44 V|
Again the idle +12V and +5V lines wave only a hundreth. The stress measurements shows that +12V rail waves a little more but +5V acts like idle voltages.
During the tests Silverstone SST-ST30NF was as quiet as 0dB power source can be. But what about the case and the power source temperatures? The temperature LED indicator didn't turn red, not even a single time. It was quite warm all the time, but not enough to actually burn the skin. The power source was installed in a case equipped with two case fans. During the tests the case temperature rose about 2 degrees compared to a power supply equipped with a fan. That is why using a case fan with SST-ST30NF is more than recommendable to keep the case temperatures check.
