there should be a label on the backplate showing the max. power consumption from the electrical outlet. That is important because users likely have many devices connected to the same residential circuit (sometimes shared by multiple rooms), which should not be overloaded (not everyone has a separate 20A line for the AVR).\n\nI agree. As I said, there is no power labelling standard which all vendors would agree to adhere to. Therefore, the industry seems reluctant to act as one on this simple issue and currently does not give monkeys for consumers. One brand tells you 500W, another one tells you 730W, and both numbers are derived from different calculations. \n\nThis is not imaginable in PC power supply industry. There is clear labelling of output power, broken down to minute details for each power rail and socket, plus label for power efficiency standard. There is greater degree of scrutiny of power supplies as stand-alone component and product.\n\n\nIf food industry can agree on labels (when governments force them to...), you can clearly see why AV industry does not have labels or cannot agree how to certificate HDMI 2.1 boards. It's absolutely bizarre what they are allowed to do without minimal self-regulation and standardization. Gene discussed power issue in one of his videos.
