Operating SystemVista Ultimate 32-bit

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 for 24 hours. All voltage rails were measured using a digital multimeter by tapping into various connectors. In addition to these stressful application running, the graphics card was overclocked.

The ePOWER EP-350-CD UNI has a very good voltage regulation. Voltage fluctuations were minimal and stayed well within ATX standards. Three 40mm fans were fairly quite and kept power supply cool.
