CRPS defines a standardized electrical and mechanical specification of server power supply. The supply is a case enclosed design with a gold finger that connects to system backplane. Starting from 550 W to 3,000 W, the width and height of the modules are fixed, only length varies. There are a single main output and a standby output from CRPS for systems that will ensure a simplified system design with very high efficiency. PMBus is responsible for the communication between the power supply and system. With these powerful features, CRPS satisfies every server application in this industry.
