Idle voltages were measured by powering the system at the default speeds, and voltages with no applications were running for at least 30 minutes.
The load condition was established by running loops of the SM graphics test from 3DMark06 at 1600x1200 resolution with enabled 8x AA and 16x AF and Orthos (4 cores) at the same time for 24 hours. All voltage rails were measured using a digital multimeter by tapping into various connectors.
In addition to these stressful applications running, the loaded system was overclocked and overvolted to add more demand to the CPU and graphics card.
The CUQ-1200B has excellent voltage regulation. Voltage fluctuations were minimal and stayed well within ATX standards. Its 135mm and 80mm fans kept power supply quiet and cool.
