Just curious-looking at your basic powered mixers for roughly the same money you can get a Peavey, Yamaha,or Behringer-but the Peavey and Yamaha's show roughly half the output power as the Behringers. What gives? Seems like the Behringers are overpowered for where his mixers are typically used anyway?
Back when I was engineering manager or product manager over powered mixers I could give you an answer from personal inspection. These days I do not have first hand experience with these models, nor do I really care.
I hope that the new Behringer is not inflating their wattage if they want to be taken seriously, and I do not expect that they are.
The obvious thing is to check the spec sheet and look for any fine print. Power amp companies have not been free to make up their own power metrics for years***. UL and agency testers will test the products based on their reported power output. Since the safety agencies do not read magazine ads, it is often important to look at power numbers and speaker load minimums, screened on to the back of the unit. These will be real numbers.
Perhaps the Behringer does have twice the power of the Peavey and Yamaha. They are a low cost manufacturer, and there is a new trend in the industry for low cost power amps that should evolve down into powered heads. I don't expect Behringer to be half the manufacturing cost of Yamaha or Peavey, but power amplifier cost is not linear, i.e. bigger amps are cheaper per watt than small amps.
When trying to compete against well established players you need to come up with a merchantable difference to win that contest. You can offer the same for significantly less cost, or more for the same cost. If the amp power is the most important feature to you, the Behringer sounds like your mixer. Good luck.

*** there is an unwritten specification covering amplifier duty cycle, or how long it can play how loud without shutting down. Again I do not know if all three have similar long term duty cycle. Some of the new amp technologies are more efficient so should do better at this metric. While old school amp technology is time proven reliable by many users over several decades.
