In the absence of high end load testing equipment, HTL will conduct a real world test and load the power supply using components that can often be found in a recent gaming system and try to produce a ~50% and ~100% load when under OCCT. Some components might be overclocked and additional peripherals (fans, USB accessories etc.) might be connected to achieve a ~100% load. All components are tested inside a mid-tower case and room temperature was kept at 25C for the duration of the tests. The +12V, +5V and +3.3V will be measured using a digital multimeter and the total system load will be measured in Watts using a digital power meter. For additional heavy gaming system loading scenarios, 3DMark 11 will also be used as a benchmark.
In this particular test, the idle and ~50% load OCCT testing was conducted on a dual-SLI setup with all the default motherboard power saving features enabled. For the 90% OCCT load testing, the CPU was overclocked to 4.7GHz and a third GTX 580 was added for a TRI-SLI setup. The GPUs were also overclocked and several USB accessories and additional HDDs were attached to reach as close to the maximum load as realistically possible. The 3DMark 7 load test was done on a dual-SLI GTX-580 setup with an overclocked CPU of 4.7GHz.
