The entire wattage is guaranteed to be output at an ambient temperature of 50°C, and the 80 PLUS Bronze certification ensures that up to 85% energy efficiency is maintained in real-world load conditions, keeping heat down and reducing the amount of power the system draws. Protection of the internal computer components comes partially from the 0.99 Active Power Factor Correction, which feeds a consistent and clean amount of power, and protection against current, voltage and power fluctuations are all built in.
