In Win Commander II 1200W Power Supply Review

In Win, the company that brought you many different types of cases in the past is now upgrading one of its power supply series into the 80PLUS age. The Commander II series of power supplies, the successor to the original Commander, are available in three different models: 750W, 850W and the 1200W, which we have to review today. All three models are 80PLUS Bronze certified, have an army green color scheme and a silent 135mm fan in them.
