"The Tuniq Ensemble 1200 Watt Power Supply is the single largest PSU tested to date. There's obviously an enormous amount of power produced by the unit as well as an extremely respectable power efficiency rating. When purchasing this kind of PSU, you expect stable, reliable voltages for optimal system performance and it does not fail to deliver either. Granted it's large and heavy, but again, when you need this kind of power, comfort is the last thing you should concerned about. It's the Hercules of power supplies."
