Running Overclocked:
Testing the power supply is a tedious task. Like cooling products, the "proper" testing method is long and strenuous. It involves high end equipment and testing materials that we simply cannot get our hands on. A simple proper testing method would be to test the wattage draw from the AC outlet, voltage rail fluctuations, wattage fluctuations under high operating temperatures, power efficiency, and the power supply's reaction to low input voltage. But because this site is dedicated more to overclocking, we'll check for voltage fluctuations in an overclocked environment. After all, that is what overclockers generally care about.
Results:
To test the
power supply, a digital multimeter was used. For idle voltage readings, the
system was left on the desktop not running any programs. For full load, the
system ran 2 instances of CPU Burn-in, Prime95 torture test for maximum power
consumption, PCMark2004 hard drive benchmark, and the Nature test in
3DMark2001SE. CPU Burn-in is a good program to maximize the CPU load. The
Liberty 500W did not even break a sweat!
