+12V Rail Tests

We measure voltage output at 22.5W, 50W and 100W load levels, and then at load levels in 100W increments up to the maximum rated wattage. This generates a lot of results, so we have left some out and, for ease of comparison, we have split the load levels into three categories: low (<200W), medium (300W, 500W, 700W) and high (900W, 1,100W, 1,200W and 1,300W if applicable). Higher loads are more likely to highlight any instabilities. Any output that falls outside of Intel's specifications is considered a fail and highlighted in red.
