The Powerbird was initially released in a 900 and 1100 model but a lesser wattage 800 watt unit soon followed. Each of the power supplies sports a maximum 87% efficient rating and six 12 volt rails. From all the numbers and specifications I am throwing your way you can see these power supplies mean business. So much business that HP selected the 1100watt, which we are reviewing today, to use in the Blackbird gaming system. We will now take the Powerbird for a spin to see if it is right for your high performance rig.
