The wattage of an RGBW (Red, Green, Blue, White) LED strip can vary depending on its length, brightness, and the efficiency of the LEDs. However, a typical RGBW LED strip might consume around 4-6 watts per meter when all LEDs are at full brightness. Keep in mind that this is just a general estimate and the actual wattage can vary. It's always a good idea to check the specifications provided by the manufacturer for the exact wattage of the LED strip you're using.
