Recognizing the need for a wide range of power supplies, Cooler Master has expanded the Real Power Pro family to include six different units from 550W all the way up until 1250W. The Real Power Pro 850W is the second unit in the Real Power Pro family we have had the opportunity to review, and we are incredibly pleased with its performance. If these two units say anything about the Real Power Pro family, we could not possibly be any happier.
