No, I was not referring to what load in Wattage the Power Supply could, draw from the wall. Many Power supplies can output more than their rated wattage, some substantially more. My comment was referring to operation towards peak EFFICIENCY (wattage) - and that peak
efficiency of many Power Supplies occurs around 50% loading.
Many apologies if my comment was misconstrued.
Having viewed the linked reviews, I note from the graph/s that PEAK efficiency occurs somewhere around 45 %, straight lines to around 55% -at which it delivered 85% efficiency - and then falls away to an eventual 82% efficiency at maximum output. While I concede that the drop from maximum efficiency is only 3% at maximum output, and substantially better than many, the PS components are still becoming more highly stressed as loading is increased . Especially, with the fitment of less than optimal Teapo 85 degree capacitor/s to the unit in question. I prefer to have my PC operate somewhere within PEAK output. While more expensive to purchase the initial Power Supply, it should hopefully be rewarded in more stable voltage/s, ripple, minimal heat, less hardware failures and cheaper power bills.
