Overview
ChiconyPower's CRPS and M-CRPS families are the workhorse power supplies behind mainstream server, storage and networking platforms: a 1U rack-mount enclosure measuring 73.5 x 40 x 185 mm that is narrower and shorter than the previous generation, freeing system space for compute and airflow. The range runs from 550 W to 2400 W on a common Common Redundant Power Supply footprint adopted by cloud customers and OEMs.
Every unit is digitally controlled over an integral I2C interface using the standard PMBus protocol, which is what allows a host BMC to read telemetry, set throttling and manage cold redundancy across hot-plug N+1 or N+N configurations. Efficiency sits at 94% Platinum today, with Titanium designs ready for development to meet ErP Lot 9.0 requirements.
The efficiency and peak-power behaviour comes from Chicony's Ultra Power Block technology, a high-density packaging scheme that integrates the secondary synchronous-rectification MOSFET, output choke and capacitors. Combined with a common hardware and firmware module concept, it keeps part count and production lead time down - useful when a platform needs 1300 W, 1600 W, 2000 W and 2400 W variants on the same chassis and connector.
Key Benefits
One footprint, six power levels: 550 W through 2400 W on a standard CRPS 1U envelope. Fully digital management: PMBus/I2C control enables telemetry, throttling and cold redundancy. Density and light-load quality: Ultra Power Block packaging improves peak power and iTHD at light load - where AI servers actually spend most of their time.
Applications
Rack servers and GPU server chassis, storage arrays, networking and switch platforms, cloud and OEM N+1 redundant power, industrial computing systems requiring hot-plug PMBus supplies, 48 V rack power shelves.
