Because it is designed for the +3.3V and +5V rails, this highly effective DC-DC board aids in more accurate voltage regulation and improves system compatibility for components of the next generation. It is built to function without difficulty at temperatures as high as 40°C and altitudes as high as 5000m while delivering constant, reliable power production. To comply with worldwide ErP Lot 6 criteria and reduce total energy consumption, it was also designed to be extremely power-efficient when in power sleep mode. Direct power connections in a dark color help components blend. The DeepCool PK550D 550 Watt 80 PLUS Bronze Power Supply comes with a 05-year warranty.
